Need engine recommendation (Yamaha)
Greetings,
I have been lurking awhile but am new to this site. I'm thinking of upgrading my 17' Gregor (hull wt 925#) from a 40hp Nissan 2-stroke. Max mfg. hp rating is 70. The boats sports a 6hp 4-stroke kicker. Minimizing engine weight is a top consideration. Thinking of using a 70hp Yamaha 2-stroke. Any other suggestions? Any problems/reservations concerning this particular Yamaha? With a 4-stroke kicker, there seems no reason not to enjoy the superior torque of a 2-stroke. What sort of price range might I expect for selling a low-hour, 40-hp 2002 Nissan? Your thoughts appreciated... -John |

That way you don't have to fuss with oil anymore and can hook the two engines together with a T-fitting to run off the main gas tank rather than carry two gas tanks. The new kicker on my Ranger is a two stroke 40 hp ETEC which has an onboard oil tank - I wouldn't have done it unless it had a seperate oil tank - two oil tanks would have been a pain in the... At least that's the way I would go. As far as four strokes, don't know much about Nissan engines. Do know about Suzuki engines and they are reliable (their service network can be suspect though) - we have a contributor here who has bigger Squeezukis and he likes them a lot. Honda is a possibility - the Euros who run small boats love Hondas. And of course, in the opinion of some, the finest four stroke on the market is Yamaha. About the only thing I know about Nissan is getting them serviced if something goes wrong - I don't think they have a very strong dealer/service network. In that sense, Yamaha is probably your best bet - they do have a strong dealer/service network. |

The gas tank holds 16 gallons. At 4,200 RPM I use about 2 gallons per hour. I'm very happy with the motor choice. |

Any idea what the gph consumption of a 70 hp 2 stroke might be?
Unless I'm missing something, I'm not overly concerned about pairing a 2 and 4 stroke main and kicker, provided that the 2 stroke is oil injected from a reservoir under the cowling. I can use one fuel source, right? Is the fuel consumption of a 2 stroke roughly comparable to a 4 stroke? I know there are differences between carburetion and efi-- just looking for a generalization. I prefer a light engine on this light boat. Thanks, John |

4-strokes fall on their ass in this application because you have to make sure you don't just lay it or carry it in any position where the oil in the sump can run out or run back up something important like a vent and flood the ending with lube oil. We have two Evinrudes with the fuel tank mounted on them. You can close two valves, one for gas, one for the vent. As it happens, they are never tipped much, storage is upright in a beach box.

Most of what you fellows do, 24-7, is either fling juvenile insults, discuss subjects that have nothing to do with any aspect or boating, or act like idiots. Because of you and your dwarfs, I simply gave up on this place as a forum for boating discussions, and I freely admit I show up mainly to watch the aberrant behavior of you and your buddies. If all you did was "watch", a good chunk of the problem would go away. You don't "watch". You (and others) pounce upon certain individuals regardless of the subject of their posts or to whom they are addressed. The only way to restore rec.boats to something other than a personal insult free-for-all would be for everybody to retire the past, forget about old issues and conflicts, and post as if all were meeting for the first time. Problem is, it would require 100% participation and that just isn't going to happen. Eisboch tell you what, Richard, as an old Westvillian to an aging Amityite, you work assiduously on getting the seven dwarfs to behave and I'll work on the rest. how's that? No thanks. It would be like trying to solve a Catch-22. *I* can't fix it. *You* can't fix it. But if all the participants were seriously motivated and committed to reviving rec.boats to it's former glory, it can be done by simply resisting the urge to post idiotic claims/counterclaims. It can't be "my" rules .... "your" rules or anybody else's "rules". Eisboch Well, then, I go back to my original post on this to you...that as a boating newsgroup, this place is lost, and that I show up mainly to watch the aberrant behavior of the seven dwarfs and (as you mentioned) to crap on one of their heads from time to time. None of the seven, so far as I can tell, has the slightest interest in boating related subjects or, if they do, they seem incapable of making any but the most empty headed of posts (e.g., I took my kid wakeboarding yesterday, or, I took my 93 grandchildren on a cruise). So... Harry, your statement, "I show up mainly to watch aberrant behavior...", is belied by the sheer quantity of attack posts you make here. I am willing to make you a deal. I will make no posts on Chuck's Island if you make no more than one more post here, in answer to this one. Look what you'd have to gain! Deal. Not that you had anything to add, boating-wise, there or here. |
