My 1985 Mercury 75
So this week I'm going to get around to installing the aftermarket
power tilt & trim I bought over the winter. My lifting method is going to be a come along and a good, solid tree branch in the back yard. I did a bit of digging, and see that there is threaded area in the opening AROUND the bolt that holds the flywheel on. Apparently this is designed specifically for an eyebolt that you can use to lift the engine. Problem is, I can't find a part number on the Mercury parts catalog online for my particular engine, and I don't want to blindly order one off eBay. So, the question is.... Does anybody know if the lifting eyebolt threads are "universal" across model years and sizes as is suggested by the Amazon and eBay parts I've been able to find? |

I picked mine up with a sling under the power head, right around the lower cowl. I made a circle of rope smaller than the cowl and 2 ropes going up and over, creating 4 lifting points. Hook the come along to the loops created at the top. The 1989 Merc/Yamaha 75 I had used a 36mm threaded insert that doubled as a flywheel puller but I am not sure the older one was metric. I never found one for less than $100 in those days and I was not doing it. |

So I was able to find thread information for the plug that covers the flywheel nut (its missing from my motor, or else I would have just taken it to a hardware store and found what I needed). So I'm going to try this part from amazon: http://smile.amazon.com/dp/B00MPUM03S A combo flywheel puller and lifter for $40, with free same day delivery. Why not? Good use of an Amazon gift card. That looks like the one but mine was supposed to be metric since that powerhead was a Yamaha, licensed to Mercury. My 2002 Merc had lift rings on the block, as does my F70 Yamaha. (again, the same block) |

I have to help him with a pier install in exchange, but I think that's a reasonable price to pay. The only thing that went "wrong" was the new steering cable I put on last year was about 6 inches too short to reconnect, so I had to buy a 14' cable. Switched that out in about an hour the next day, and we're all good. There was great debate over whether to lower the engine a peg, since now it sits a little higher when vertical, but with the additional setback (about 7") and additional down tilt, we figured the water would be quiet enough to give me good performance. I can always lower it a notch if I don't like the way it performs this weekend. |

I can always lower it a notch if I don't like the way it performs this weekend. And the answer is... I don't like the way it performs. Oh, it gets on plain super fast, but now I have a HARD pull to the right. I know I should be able to tilt the motor back up to about vertical, but now at cruising speed, vertical brings the prop up too high and I get excessive revving. Am I right in thinking that the hard pull is because the motor is tilted in too far? Will lowering the motor a inch (or two) actually alleviate the problem by letting me tilt out farther? Thanks! |

Have you tried adjusting the trim tab? Won't the trim tab only give me neutral steering at one specific tilt and speed? You'd be surprised at how much a little tweak in the tab effects steering effort for better or worse. |

Here's a link to some info you've probably already looked at. http://www.thehulltruth.com/boating-...uld-cause.html Yes, that is one of the first threads I read. I had thought about a NFB helm when I was replacing it last year, but I'm glad I didn't. While it stay on tack if I let go of the helm, I think I'd still have the issue of it being very difficult to turn the wheel to the left. The best line I got out of that thread was: "I can't find it right now but Mercury Marine used to have words and music describing propeller torque. It was crystal clear that when the motor is trimmed down/in torque will want to make the boat turn to the right. When the prop shaft is parallel to the surface of the water the torque (effort to turn right or left) will be the same. When the motor is trimmed up/out the boat will want to turn to the left. The procedure is to find the trim setting that provides most efficient operation. Then adjust the trim tab anode, if necessary, to eliminate steering torque at that trim position. " |

Have you tried adjusting the trim tab? That might help but I suspect he's getting bow steer. He needs to lower the motor and make sure he has some bow lift and the bow wake starts about 1/3 of a boat length from the bow. Once he has that he can tweak for the performance he wants. So that being said, if I had neutral steering before I added the 7" setback from the power tilt unit, Do I need to drop the motor down 1" to make it equal with its height prior to the modification, or do I need to drop it farther? |

If I still have some pull, I'll play with the trim tab. If it pulls to the right, I need to adjust the tab counterclockwise, correct? |

Oh, it gets on plain super fast, but now I have a HARD pull to the right. I know I should be able to tilt the motor back up to about vertical, but now at cruising speed, vertical brings the prop up too high and I get excessive revving. Am I right in thinking that the hard pull is because the motor is tilted in too far? Will lowering the motor a inch (or two) actually alleviate the problem by letting me tilt out farther? Thanks! Have you tried adjusting the trim tab? That might help but I suspect he's getting bow steer. He needs to lower the motor and make sure he has some bow lift and the bow wake starts about 1/3 of a boat length from the bow. Once he has that he can tweak for the performance he wants. So that being said, if I had neutral steering before I added the 7" setback from the power tilt unit, Do I need to drop the motor down 1" to make it equal with its height prior to the modification, or do I need to drop it farther? There's no formula. It's all trial and error. Alright... Sounds like I should lower the motor so that when vertical, it is at its original depth from before I installed the power tilt. If I still have some pull, I'll play with the trim tab. If it pulls to the right, I need to adjust the tab counterclockwise, correct? I believe you are correct. -- Ban Krausescheiße-spouting narcissists...not guns! |

Look at that knot they use for nets, rig 4 up leads and make the basket a snug fit around the leg and up you go. That was going to be my next option if I couldn't locate the lifting eye. Now that I did it once, I feel more comfortable doing it without a crane. I'll use the ol' "Lower the rear of the trailer as far as it will go, hook a chain to the lifting eye, secure to a thick tree bough, remove the bolts, raise the rear of the trailer, rebolt" method to move my motor down a notch. I've got a nice maple in the back yard that should be perfect. Should go a lot faster than trailering an hour up to Manitowoc to use the overhead crane. I rigged a lifting eye over the garage door for stuff like this. It is hanging on the lower chord of the truss, right against the wall. |
