O'Day 28 outboard motor question

[mike c]

ahh, the question I never thought I'd ask. My OMC saildrive died last year and I put a 9.9 hp outboard on the transom to get me through. It worked, but the 9.9 barely got me moving through the water and in a chop I crawled. Also, in a following sea, mostly due to stinkpot wakes on teh stern quarter, the motor cavitated way too much for me. I want to move up to a 15 hp. My question for those of you who have an outboard on your 28 ....what type of outboard do you have and what type motormount do you have holding the motor?? I am planning on getting a new Yamaha 15 hp 2 stroke (to save weight)long shaft and a new motor mount that will lower the motor deeper intio the water.ThanksMike C.O'28 "Da Capo"

Outboard

Mike, Check the archives. Last year much talk about this. Mounts and motor. I remember Flyhop was one who did it. I know that you need one with about 15" travel and a wedge or Garelick bracket to mount it to.I will look up the numbers i used. Never had a problem with motor coming out of water. I have a Honda 9.8 and have no problem pushing boat to hull speed or over.

outboard bracket for 28

Mike I donot have 28 but I just went through doing the research for changing out the outboard my 222. Like you I was concerned about not being able to puch the boat in a current so in my case I went for the Honda 9.9 long shaft. I also whent with the Garelick 7091 motor mount which gives you 15 inches of travel vs the 7090 wich is 9 inches. That will put you r shaft in deeper so it will not be as likely to come out of the water. I hope this helps.

Outboard power

Mike - I don't have an outboard on my O27, and never want to get involved with one for aux. power after sailing on a friend's boat that was so equipped. It was an older boat, with long overhangs, so was a lot more vunerable than your O28 to having the motor cavitate when the boat was pitching or when someone went up to the bow to pick up a mooring, but the experience left me with a firm prejudice against OB power for bigger boats.That said, you'll get better results if you find an OB that was designed for an aux. power application, rather than a general purpose motor. The purpose built models have more reduction gearing and turn a larger diameter prop at lower speeds, which will provide more thrust. An additional benefit is that they have alternators ( small output, but better than nothing) That was where the old Seagull motors really shone: they had a lot of gear reduction and turned a fairly large wheel, so would move a pretty big boat with very little HP.

thanks all

Thanks for all your sugestions. I'm getting the garelick mount for my outboard. A Yamaha 15hp long shaft with electric start and gear/throttle shifter in cockpit.I am ONLY keeping the outboard for a year. Next year I am installing a new Diesel saildrive. Then I can either sell the outboard OR buy a kickass Zodiac to put it on : )
