I am new to sailing and just bought a 1980 25 foot oday with an OMC sale drive. It took three days of sailing for the engine to begin to give me problems. One of the previous owners put an outboard transom mount on the boat. So I'm considering switching over to an outboard. Has anyone done this and if so what brand and size outboard you switch to?
I did this on my Cat 27. The 15 hp 2 stroke Zephyr OMC saildrive was submerged for who knows how long. I pulled it out and plugged hole with a 1/2" aluminum plate. I now have all kinds of storage where the motor was. I replaced it with an 18 hp Tohatsu. I only went with that much hp because I got such a great deal on it.
7 - 10 hp should work for you. I had a 10 hp on my Mac25 and only needed to run it 1/4 throttle most of the time. Nice to have extra hp if you are in a windy area and need to fight off head winds.
I love the Tohatsu brand an parts are easy to find on line. If you can afford it get and electric start and add remote controls.
