I want to install a Yamaha 9.9 4-stroke long shaft in the motor well of my Cape Dory 25 located in Mission Bay(salt water), San Diego, CA. I have been told that it must be taken out of the water regularly in order to protect it from serious harm. This is impractical because of the motor well and engine weight (95 lbs). My old motor, a Johnson 7.5 had not been used in 5 months and froze up, no starting, no gear shift lever motion in addition to lots of barnacles. The boat had previously been in Lake Tahoe(fresh water) and these problems never occurred. Help??

Re: CD25 outboard motor
You can buy a spray-on anti-fouling mixture at any marine store. That should do more than enough to protect your engine.

Re: CD25 outboard motor
Anti-fouling paint will only help the exterior. The water pump and water inlet passages will continue to be the target of corrosion and marine growth. The only answer I've found in more than 20 years is removing the engine from the well whenever possible, particularly if the boat will be unused for several days. Might I also suggest that this will be much easier with a smaller, lighter engine. A 50 lb., four stroke, 5 hp engine is actually much more suited to a CD25 than anything larger. Also, you'll find with the smaller engine that you'll store it in a seat locker when sailing offshore long distances. The boat sails much, much better without the weight and drag of the engine.Jules Minsky wrote: I want to install a Yamaha 9.9 4-stroke long shaft in the motor well of my Cape Dory 25 located in Mission Bay(salt water), San Diego, CA.

Hi Jules,
I remember pitch poling a Hobie Cat in Mission Bay about ten years ago. I clearly remember flying through the air as the mast hit the water ahead of the hulls! That bay is a really pretty spot that I never got back to (as I promised myself). Is that rental place still there with Hobies & Prindles etc? Doesn't matter; I think I am still banned!
I think a 9.9 is too big for a CD-25. Mine had one (a two cycle) and it was too much motor. The four cycle will be even heavier. In any case I wouldn't buy a 25". I think a 15" or 20" would be fine, depending on whether or not I lower the bracket. These boats sit low in the aft end anyway.
I would suggest a five or eight horse. I have a two cycle eight now, and it moves the boat just fine with a sail prop. If I were to repower now I think I would go with a four cycle five horse motor with a 15" shaft. The four cycles give much better fuel efficiency, thereby increasing range under power. They are also much quieter - I can't use the VHF with my two cycle running, and that is a real pain when calling in for a mooring. That is a valid safety concern. Remember - the CD-27 came with a seven horse diesel, and that boat weighs nearly twice as much as a CD-25 (7500lb v. 4000lb). The CD-27 has adequate power.
If you do get a four cycle, be careful how you store it. I like to keep my motor in the locker, but a four cycle is very position sensitive. The oil leaks out of the pan if it is laid on the side. Still, I think a bracket could be made to hold a small four cycle upright enough to keep in the locker. What ever you end up with, be sure it has a sail prop on it, not a speed prop. This thrust is what allows the smaller motors to work well with these boats. A speed prop will just cause cavitation, no matter how much power you feed into it. The sail prop is designed for our low speeds, and gives a good push.
I have a discussion on the motor issue and how I resolved it on my boat's web site. Take a look at:

Good Luck,

Re: Been There!!
Don't know about other 4 strokes but my 8hp Honda is designed to lay on its side (the side designated by Honda) not the opposite one. Says so right on the engine. (Ditto for my 2hp Honda dinghy motor.) My 8 hp has plenty of power. Seems just about right keeping in mind you might someday want to fight against a strong tidal flow or river current. If this is not in your future a 5 would most likly be fine. (Maybe even under the heretofore mentioned load. I know there is at least one CDer following this site who has a 5.)Jon wrote: Hi Jules,

I left mine in the well for three months while we were in the Keys this winter. Used the tin based spray kit sold by Tempo. This worked well to keep off the critters but the "grass" still grew wonderfully. Had to get in the dinghy twice to "mow" the engine.

Good Points
Good points Jim.
I didn't know some four-cycles could be laid on their side. I thought they all had to be laid on the clamps with the back part straight upward. The ability to lay them over makes it much easier to plan a cockpit locker storage scheme. Next time I look for a motor I will certainly take a look at the Honda four-cycles.
Thanks!
Jon
