Hello everyone. I have been an Oday 22 owner for about 8 years now. Recently she was pirated and the outboard stolen. A friend gave me a very nice Chrysler (older- '82) 35hp long shaft. I would like to ask if the motor mount could support the weight of a 150lb outboard, and what might this do on the water to have such a large engine. Typically I only use the outboard to get in and out of my canal (previously 6hp), but the last thing I want ot do is bust through the glass of the transom and take on massive water. Not to mention lose the outboard my neighbor so graciously gave me. Anyone have experience with higher HP outboards on their sailboats? Any suggests are greatly appreciated. Thanks! Fair winds, Mark

too big

That would be waaayyyyyy to big Mark. You are absolutely right about the weight on the transom, if you were to consider this you would need massive backing plates and still then I would be worry. Sailing wise 150lb at the outer end of the boat would make the boat rock alot and being on port (or starboardside) would change the characteristic of the boat from one tack to the other. In any case just because of its weight on the transom I wouldn't do it, I would even be worry to have all that weight on the transom in any kind of chop. I usually take the outboat off the transom while sailing any distance and put it down below over the keel. I think a 9.9 would be over kill on your 22' a 6hp is probably perfect. I would suggest thanking your neighbour, asking him if he would mind terribly if you used the engine as exchange for something more suitable to your boat and get yourself a new (newer) 6hp! Happy sailing, a.

Mark, IMHO a 150 lb; 35 hp motor is waaaaay too

much for your boat. Even if you use the throttle sparingly, that much weight on the stern will affect your sailing and may damage your bracket (which was most likely designed for 60-80 lb) and will be a PITA to raise from the down position. I hate that your emgine was stolen; maybe your friend would be OK with you using it to trade in for a new 5-8 hp ??? Good Luck, Clark

Bracket????

Yup,, Way to much. Is your Outboard on a bracket? It may have the max engraved on it. I am guessing but 15 HP would be push. 6-10 about where you awght to be.

sell the 35HP

The previous sailors gave you some good advice.... 35 HP is way too much for a 22'. Why not sell the 35HP and invest in a good used 8 HP motor?? It's off season and you may be able to pick up a bargain. Just my 2 cents worth...... Cheers!!

Thank you

Thank you all for your suggestions. Of course this makes sense to me as well. Tacking as well as the extra weight on the transom in a chop where my biggest concerns as well. I will take your advise and go at this problem with a new approach. Thanks! Mark

Too big

I use a 9.9hp 2-cycle motor on a Mac22, and its not too large. The weight is the same as the 8 and 15 hp motors because they are the same motor, just differently tuned. The newer 4-cycle motors might be a little heavier; I use a motormount rated at 20hp which wobbles less. A good backing plate is recommended, especially for trailering. This subject has been explored extensively in the past, the consensus has usually been for 6-8hp for coastal areas where currents and hazards are higher, and 4-6hp for lakes, etc.
