Need Info on Yamaha 8hp Outboard When It is Fully Tilted Up
I would like to know some info about Yamaha 8hp High Thrust 4-stroke
outboard motor when it is fully tilted up. I am planning to get that Yamaha motor as a kicker for trolling and backup. Unfortunately, I cannot mount it directly on the transom of my boat. The reason is that the transom only has one opening for the main motor. The boat has a container in each side of the opening. I cannot mount the motor over the container because the container is a flimsy structure. I will have to somehow mount the motor at the back of the transom. I could have installed a manual-motor-lift (such as the one from Garelick); but I am looking for the version of Yamaha 8hp outboard that has a power-trim function. This means instead of having the outboard lifting straight up and down, I will have it tilting up and down. Seem like the best way is to install a motor bracket behind the transom, mount the 8hp motor on the motor bracket, and has the 8hp motor kind of sticking out. The question is how far that I should have it sticking up. If it is not sticking out far enough, the cowl of the motor will hit the container that I mentioned above when the motor is fully tilted up. If it is sticking out to far, I am afraid that it will add too much stress on the transom. I want the motor bracket sticking out just far enough not to hit the container when the motor is fully tilted up. My questions a 1. What is the distance between the far end of the cowl and the motor mount when the motor is fully tilted up? 2. Any downside of doing this? 3. Any better idea? Thanks in advance for any info.

Jay Chan Great motor. Mine is mounted maybe 12" back on a solid to the boat bracket. You have to look at the shaft length you need. I have the extra long 25", which allows me to mount the motor bracket higher off the water, and when the motor is tilted the foot is out of the water. Your dealer should have some required measurements. |

This year I installed a Garelick lifter for my Yamaha 9.9 high thrust 4 stroke.
It is a somewhat heavy (100 lb.) engine, and thus the necessity for an assisted lifter. What I did to support the engine was buy a big piece of stainless steel plating, which I used as a backing plate for the Garelick. This distributes the load across a larger area of the transom. As far as the mounting height, if you go to the Garelick web site or one of their vendors, you will find some mounting instructions. I also was worried about the engine hitting the transom when fully tilted up. I solved this by introducting some hardwood shims between the bracket and the transom to move the engine further astern. I have the long shaft engine, so I got the Garelick with the greatest lift height (about 11 inches, I believe). You then have to position the bracket at the height on the transom which will get the prop low enough in the water for rough following sea conditions, yet high enough to lift it clear of your transom. The Garelick has 4 lockable positions for setting the height of the engine for various sea conditions. Hope this helps, Sherwin D.

Larry, I'm not disputing your word, but are you sure there would be an
oil problem? The reason I ask, is because I have a 4-cycle weed eater,a nd it doesn'tmatter how you lay it, nor what angle you run it, there hasn't had a problem with oil leaking or foaming out of where ever it can get out. Just curious.... Larry wrote: " wrote in oups.com: 2. Any downside of doing this? Yes. It's a 4-stroke with OIL in it. You must be very careful the OIL in it doesn't go where it's not supposed to go. You can only lay down a 4- stroker certain ways, and even then I'd be deathly afraid the oil would be splashing around in there where it's not supposed to go, laying down like that, while you were underway with the other motor. Too bad it's not a 2 stroker. It wouldn't matter, then, especially if you took the stupid oil injection off it and premixed its gas the way a 2- stroker is supposed to be run...dry. I like the lift idea hooked to the stern....the kind they use on the stern of outboard-powered sailboats that lifts the hole motor back then up to lock into a totally dry position above the stern while underway. The motor would be parked in its proper upright position where the OIL is not an issue. You can even work on it if it's broke, that way. Larry -- My calendar must be wrong.... In all the stores, it's ALREADY Christmas! |

Geez, you'd think it was a diesel! Love the "High Thrust". I'll bet it's as high as any 9.9hp outboard...putting out 9.9hp like it does...or is supposed to....(c; Those marketing guys invent some great stuff, don't they? I have a Yam 3, 2 stroker. You can carry it with one hand, even if the gas tank on top of it is full of premix 2-stroke gas! Funny thing is, I can't find the cooling water ****er on it. A little water comes out the pressure relief hole in the exhaust and it doesn't overheat so it must be fine. I'd still like to see water ****ing out of it, but it never has. Little thing planes a 9.6' Watertender dingy if I set in the middle seat (255 #) and leave my 2 gallon jerry can in the bow. One of the dock neighbors of Lionheart had the boat sitting in just awful conditions, flooded with rainwater, its bottom covered with beasts between his sailboat and the dock. I asked him if he'd like me to pump it out, before it sank which I found out is impossible full of water, with my rechargeable bilge pump. "You want it? It's yours. I'll bring the title from Atlanta next time I come down", he says. Never in my life have I ever turned down a free boat that was still afloat. Waste Marine sells them for $500. Another yachtie friend wanted me to come put up a motion sensor light over his garage doors. While I was on the ladder, I told him of my good fortune getting the free boat. When I was about to leave, he comes out with this hardly-used Yamaha 3 and says, "Here. It'll need a motor. My back can't stand riding in a dingy and we only used it twice. It's been taking up garage space ever since." The most I got in it was the $35 to re-register it and renew the license. My story of a "free boat" fell on deaf ears at the tax and license offices....(c; The county wants $13/year. They think its a Hatteras. My neighbors' kids think it's a Redneck Spa. They fill it with water sitting on the lawn and have more fun in it than any adult could have.... Larry -- My calendar must be wrong.... In all the stores, it's ALREADY Christmas! |

The Yamaha T8 motor is good not only because its gear ratio is supposed to be good for a kicker, but also one of their T8 model has a power trim option that is quite reasonably priced (I don't believe other small outboard has this option). Your boat must be much bigger than mine. Mine is a semi-V full 18-ft boat. I am hoping that I will only need no more than 20" shaft. I am asking this here because I want to know how long the motor bracket needs to stick out. If it will be sticking out too far, I will have to forget about this (and stick with a manually operated motor lift such as one of those from Garelick) because I really don't want to put too much stress on the transom. Therefore, this is pre-mature for me to figure out the shaft length yet; I need to figure out the motor mounting method first before figuring out the shaft length, and then I can talk to the Yamaha dealer. Thanks for the good info. Jay Chan |

I am not aware that oil from a 4-stroke motor can leak out that easily. None of the operator manual of all my 4-stroke gas-powered equipment have a warning about this. At most they ask me to turn off the fuel valve or run the motor dry before putting the motor on its side (like when I need to do an oil change on the motor). Anyway, this probably should not be a problem to me because I rarely ever tilt the motor to its highest position. Too bad it's not a 2 stroker. It wouldn't matter, then, especially if you took the stupid oil injection off it and premixed its gas the way a 2- stroker is supposed to be run...dry. I can see that a small 2-stroke is a good choice if it is being used to plane a small boat. But I will use the small outboard as a kicker and the boat will be running quite slowly. I have a feeling that I will smell the exhaust from the 2-stroke motor if the wind is blowing from behind the boat. Therefore, I will get a 4-stroke instead of a 2-stroke. I like the lift idea hooked to the stern....the kind they use on the stern of outboard-powered sailboats that lifts the hole motor back then up to lock into a totally dry position above the stern while underway. The motor would be parked in its proper upright position where the OIL is not an issue. You can even work on it if it's broke, that way. As mentioned in my post, I will get a motor that has a powered trim option. This means I really don't need the manual-motor-lifter such as those from Garelick. Garelick has a powered-motor-lifter that we can use to lift a motor straight up or down just by hitting a button; unfortunately, that powered-motor-lifter from Garelick is very expensive (as much as the price of the small outboard itself). Thanks for the suggestion though. Jay Chan |

Does yours a fully-manual-motor-lifter or a hydraulic-assisted / manually-operated motor-lifter? I see that Garelick has a hydraulic-assisted / manually-operated motor-lifter. But I am not sure how well it works considering the fact that I have a "container" (box) right in front of the kicker. If I used a manually operated motor lifter, that "container" would get in the way when I tried to lift the motor up, and I would have to bending my back in an awkward angle. That is the reason why I want the powered trim option. What I did to support the engine was buy a big piece of stainless steel plating, which I used as a backing plate for the Garelick. This distributes the load across a larger area of the transom. Thanks for the suggestion of using a SS backing plate. How thick the backing plate do you need for your 9.9hp motor? ... I also was worried about the engine hitting the transom when fully tilted up. ... I don't quite understand. Why do you need to tilt up the motor? If your motor lifter is going to lift the motor straight up and down vertically, it should not need to be tilted up, and it should never hit the transom, right? Jay Chan |

Halfmoon Bay we get the best crabbing about 8 miles from the harbor in 100-120' of water. If deeper you want a puller for the pots. Lots of 14' skiffs crab just outside the harbor. Sandy bottom and protected by Colorado Reef. |

Trailering it down is possible because it doesn't extend below the bottom enough to be a problem. It's only a 12 degree deadrise but the trailer has it sitting high enough. -rick- Thanks for explaining why you can keep the kicker down while towing. Unfortunately, I don't have this option because my boat is sitting quite close to the ground when towing. Thanks again for measuring the length for me. Jay Chan |

I learned from the guys trailering Baja, and cut a length of PVC pipe and cut an opening down the side and it snaps on to the piston rod, so the motor rides on the PVC instead of on the piston. |

I wonder more about the wear it gets on the water. I had to replace the support pin on my old Honda once. See "T8 tilted" on alt.binaries.pictures.sports.ocean |

Yes, it is working fine as long as I follow a certain way to get water into the lower unit. I have already posted a follow-up. Somehow, the only way to get the water into the lower unit (and pumped up to the telltale) is to put the lower unit into a water bucket _and_ aim a water hose directly at the top-water-inlet in the lower unit. Won't work any other way (muff attachment doesn't work for it). I don't know why it is so cranky about the way it gets water though. Jay Chan |

This is not advertising hype. The reason it is high thrust is the high gearing
ratio and large prop surface area with the proper pitch. It is otherwise known as a 'pusher', as opposed to a 'egg beater'. Sherwin D.

I'll bet it's as high as any 9.9hp outboard...putting out 9.9hp like it does...or is supposed to....(c; Those marketing guys invent some great stuff, don't they? I have a Yam 3, 2 stroker. You can carry it with one hand, even if the gas tank on top of it is full of premix 2-stroke gas! Funny thing is, I can't find the cooling water ****er on it. A little water comes out the pressure relief hole in the exhaust and it doesn't overheat so it must be fine. I'd still like to see water ****ing out of it, but it never has. Little thing planes a 9.6' Watertender dingy if I set in the middle seat (255 #) and leave my 2 gallon jerry can in the bow. One of the dock neighbors of Lionheart had the boat sitting in just awful conditions, flooded with rainwater, its bottom covered with beasts between his sailboat and the dock. I asked him if he'd like me to pump it out, before it sank which I found out is impossible full of water, with my rechargeable bilge pump. "You want it? It's yours. I'll bring the title from Atlanta next time I come down", he says. Never in my life have I ever turned down a free boat that was still afloat. Waste Marine sells them for $500. Another yachtie friend wanted me to come put up a motion sensor light over his garage doors. While I was on the ladder, I told him of my good fortune getting the free boat. When I was about to leave, he comes out with this hardly-used Yamaha 3 and says, "Here. It'll need a motor. My back can't stand riding in a dingy and we only used it twice. It's been taking up garage space ever since." The most I got in it was the $35 to re-register it and renew the license. My story of a "free boat" fell on deaf ears at the tax and license offices....(c; The county wants $13/year. They think its a Hatteras. My neighbors' kids think it's a Redneck Spa. They fill it with water sitting on the lawn and have more fun in it than any adult could have.... Larry -- My calendar must be wrong.... In all the stores, it's ALREADY Christmas! |

It was pretty hefty stuff, and required some hardened drill bits to get through it. ... I also was worried about the engine hitting the transom when fully tilted up. ... I don't quite understand. Why do you need to tilt up the motor? If your motor lifter is going to lift the motor straight up and down vertically, it should not need to be tilted up, and it should never hit the transom, right? Even with the 11 1/2 inch lift range of the Garelick, I could not position the engine to both get it low in the water for following sea conditions, and also get the prop completely out of the water . Maybe my transom is higher than yours? I also find that it is easier to do maintenance and/or repair on the engine when it is tilted up. In the up position, the shims I added keep the engine from hitting the transom when it is tilted upwards. I also have the long shaft model Yamaha, which would make a completely vertical operation harder to do. Sherwin D. Jay Chan |

Just make sure you can get the prop deep enough in the water for all weather
conditions, including big following seas where the prop could come out of the water from wave action. I would not run it extra deep for calmer sea conditions, as that would not be an efficient way to run it, in that case. Being able to raise and lower the engine prop in running conditions has certain advantages. At certain depths the prop is more subject to picking up weeds or hitting submerged rocks. Sherwin D.

Thanks for pointing out the advantage of lifting the motor up
vertically vs tilting it up. I will make sure the shaft of the kicker will be long enough to handle the situation when there is a big following sea and the main motor doesn't work that I need to rely on the kicker to bring me home.
