Ever thought about a propane outboard? Clean, simple, reliable. Here's a 2.5 hp @ $1k,and a 5 hp @ $1.5k. www.golehr.com.
I wonder why they did'nt make 2 stroke OBs w propane. They do'nt need chokes so starting should be easy and they are clean burning. Hmmmmmm
I'm sure there is some reason though.

The engine would need to be oil injected........like my 40 e-tech.
JD,
You mean that's the whole point of it ..... to be green?
JD, seems to me the Evinrude people claim the e-tech series has less emissions than a 4 stroke. And the small amount of oil the engine goes through is almost scary.
I like these engines but 177lbs for 15hp is sick!
Anybody know if these e-tech's are cleaner than the 4 strokes? I think it's true but only under certain conditions like at idle or at high load or whatever.
............. We would not get the E-Tech.
You obviously have some unspecified predudice against the E-Tech, but what about the additional weight of a modern four stroke outboard on your boat? Many people have reported problems when repowering a small boat with a heavier engine.
But it produces less BTU's than gasoline not great. Less power. Never really noticeable on a forift but on a high reving outboard??
...which is why there are only two brands of outboard we would ever consider buying...
I don't have a predjudice against the E-tech technology, I have a predjudice against Evinrude motors (and Johnson and Mercury). If Yamaha or Honda were using this technology and it had a proven track record we'd probably consider it if the weight advantage made a significant difference.
The 17' Arima Sea Ranger is rated for more than 100 hp. I've seen them with 115 and 120 hp motors (2-stroke) although the most common power over the years has been 70 and 90. So I think our boat would do fine with the 100 hp 4-stroke Yamaha in terms of weight. I've seen a fair number of them so it seems to be a popular engine for that boat.
We have not yet looked into what Honda has on offer in our power range.
Our current engine only has about 300 hours on it. The problems it's had have had more to do with long periods of disuse than actual motor problems. In fact the only actual motor problem we've ever had was the partial failure of the stator last year. So for now we will continue to use the 90 hp Yamaha 2-stroke.I've read several posts on the forums that cater to smaller boats where owners have replaced two stroke engines with heavier four stroke engines and are now asking how to correct weight distribution problems as a result of the replacement.
