Well I have just purchased the Avon 3.40, and now am looking for a motor to put on it.

would a 25hp Evinrude E-tec tiller be to heavy? The transom is rated at 25hp, but the E-tec is about the same weight as most 4-strokes, coming in at close to 170lbs.

Any Ideas? or should I be looking for an older 2-stroke, as those were closer to 120lbs?

Thanks!

Yes a big plus one to that comment. I had the pleasure of knowing the man and watch him and his mates leave Tayvallich on their cruises. He had the art down to a tea especially the way they use to put all their stuff in the plastic blue bins

Now that is some impressive scenery! Really looks like a great time, the kind of thing that I would love to do..

On another note, I call the U.S Coast Guard at the Apostle Islands, and they said that I should be OK in an 11' RIB with proper planing.

Also, based on my research, the transom is only rated for around 140lbs,
So maybe the 170lb E-tec would be to much for it i'd assume? I have a line on a cheap one is why I ask...

From memory the last Yamaha 25HP 2strokes were about 48kg (=106 lbs). That's quite a difference on the back of a small boat. BUT if you are going to lift it on/off is about the limit of what is at all practical anyway (without help / specialist equipment etc). Even then its a really awkward lift - poor handholds, difficult centre of gravity etc.

If you can find a late model 2-stroke in good condition it might be worth going for.

Yea, I have found a mid 90's Evinrude 2-stroke for around $800. Also know someone with a well used 2010 or so Evinrude 2-stroke for virtually nothing. The big advantage of the late 2000's engine would be fuel economy, cost and oil injection as compared to mixed.

However the difference in 40lbs is quite a bit from the older to the newer model for a smaller boat of this type..
