Re: Lightest dinghy motor available
I think it goes without saying that the design of a 2-stroke variant will almost always be lighter than the 4-stroke equivalent.
I don't have a ton of experience without outboards, but the consensus seems to be that 2-strokes are very reliable and efficient. The smaller 4-strokes seem to be evolving after some early issues with reliability, carburetor issues, etc.
Another consideration is that 2-strokes lose oil and fuel in the exhaust ending up in the water as a sheen on the surface. From what I've read many municipalities are prohibiting new sales of 2-strokes. No idea how the USCG would treat a sheen behind the dinghy but I would be concerned about a fine for the discharge.
I saw several Honda 2 or 2.3 HP 4-strokes for sale used but a universal complaint was the noise. Also got a great deal on the 2.5HP Suzuki.
