Re: older mercury outboards vs. older johnsons
Im 32 yo. My experience in having run (all tillers, all pull start, all 2 stroke, all pre '95, ranging 6hp to 25 hp, *all* of them were completely un-maintained, meaning we showed up in the summer, pulled them out, ran them mixed new gas with the old, stuck them on the transom, fired them up, and away we went, no servicing, no stabilizing done in the fall)
2 mercs, 6 johnsons, 3 evinrudes, and 2 yamahas at our families camp in NW ontario....hard I might add...through my teens and early 20's....is that the Yamaha ran the smoothest and was easy to pull start, and had the best throttle grip system with the cable pull. Both mercs have *always* been a pain to start but once going were fine.
The johnsons are very hard to pull start in that my mom for example did not have the strength to pull start them (whereas with the yammie she could no problem). Our 9.9 Johnson was an exception easy to pull start. They always ran, sometimes excellent sometimes just good enough to keep them trolling at low speeds albeit roughly. We were always tinkering with the carb settings, and eventually we have them all running smoothly.
Experience with the Evinrudes is same as Johnsons. Our "best running" motor is now considred to be our 89 25 hp evinrude, recently surpassing the 20 Yamaha as something has happend to it that makes it cough and sputter at trolling speed now.
We are buying one new motor right now to go with a new 16 foot Naden we bought, and I had been recommending a yamaha 4 stroke (the family wants to do the right thing eco-wise). However after seeing the lastest info on fuel efficiency, fuel emmissions, weight to power, I have changed to recommending a 2 stroke Evinrude Etec 25 short shaft electric and rope (backup) start.
So yah to sum up,
I'd take an old johnson/evinrude first, then yamaha, and i would pass on mercs. New, I would have said yamaha, but very recently I now recommend the etec.
Cheers,
Ryan.
