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 O'day? Any suggests are greatly appreciated. Thanks! Fair winds, Mark

Too much
According to the Oday literature, the maximum recommended hp for the 22 is 15. I doubt the outboard bracket on your 22 is rated hold a 35 hp engine. Not only does it weigh more than the bracket can hold, it can also generate signficantly more power than the bracket/and or the transom were designed to accomodate. 35 hp is way more power than you will ever need or use. I have an 8 hp on my Oday 23; it weighs about 1000 lbs more than your boat and the 8hp pushes the boat as fast as she will go. Unless you are battling strong tides or currents on a regular basis, I can't imagine that you will need anything bigger than a 9.9 on your 22, and a 6 hp will most likely be appropriate. I am surprised to hear that anyone ever made a 35 hp outboard in a long-shaft model; long-shafts are made specifically for sailboats, and I don't know of any sailboat that would need 35 hp that didn't have an inboard engine. IMHO, you need a new outboard engine for your boat. Check the archives here for recommendations, but I think you will find that most people are now going with four stroke engines. Even if you want to go with a two stroke, you may find it difficult to find one as the manufacturers seem to have stopped making them in the smaller models within the past year or so. If you do get a four stroke, you will probably also need a new mounting bracket. Four stroke engines weigh more than their two stroke counterparts, and also generate significantly more torque; they require mounting brackets that are specifically rated to handle the loads. If your outboard mounting bracket is even a few years old, it is likely not rated to handle a four stroke engine and you will need to replace it. Unfortunately, this may mean that you will need to modify or build a new "spacer" mounting block (that angled wedge of fiberglass between the transom and the bracket) as well; the new four stroke rated brackets are larger than the older models and might not fit on the existing spacer block. There are also some posts in the archives here about how some sailors have handled this problem. When I bought my new Nissan outboard three years ago, I went with a two stroke engine rather than a four to avoid this problem. If you can't find a two stroke engine, you may not have that choice. Good luck.

15 hp is probably too much......
.....given that when those specification were written almost all outboards were two-strokes and considerably lighter than the 4 stroke outboards available today. According to a marine surveyor who has published several articles on the internet, a properly outfitted boat will have approx. 2 horsepower for each 1000 lbs of displacement. A displacement boat will only go so fast. Once it is equipped with enough horsepower to make hull speed and a little margin for headwinds, adding horsepower increases weight, cost and fuel consumption only.

hoo wee!
My Oday 22 came with a four-stroke, 10-horse Honda. It's a great engine, but it's way too much power for the boat IMO. I never open the throttle past fast idle to get to hull speed, and it swings such a big prop that docking, even at slowest idle, is too fast. I see a lot of 6 and 7 1/2 hp motors on boats of this size; wish I had one!

Thanks!
Thanks for the advise. Of course this makes sense to me. I am also concerned asbout how the weight would effect my tacks,and in chop. I'll see if I can trade it in for something more appropriate. I appreciate ther advice. Mark

6hp vs 9.9hp
During the summer my 9.9 Johnson developed a problem. After removing it from my boat and replacing with a 6 hp Evinrude to finish out the season. I have had the opportunity to compare both. The 9.9hp is too heavy, I have trouble raising it from the water, it causes my boat to list on the mooring, on port tack, the boat is more tender. I only use half throttle, but twice the gas. The 6hp has remedied all the above problems. I run it at full throttle with the same results as the 9.9hp.

5 hp in O'Day 222
My 1986 222 came with two motors. A 5 hp Honda and a newer 5hp Nissan.. I use the Newer Nissan and get good 6 to 7 knots GPS it is adequate for Lake Erie. It cost more for me to mow my lawn than run my sailboat. Hee He. Considering my power boat can suck up 45 gals in a half a days cruise. At about half throttle I do about 5 mph but when I go WOT it is not that much more speed. As Joe mentions the boat has a hull speed and that is where everything is most efficient. I think I read hull speed on a 222 is about 6. something.
