I've got an old 1985 Capri 14.2 that my dad dismasted about 15 years ago, and it's been sitting in a lot ever since. This past easter, I went up to where it was and got all the lichens and live oak dust off of it with a power washer. It cleaned up really nice. I am planning to turn her into a Shallow water runabout type thing that I can fish out of. I still need to take the centerboard out and glass in that hole, sand and paint it, fix the cuddy hatch and lots of other things. I'm looking for the highest HP I can get on the back without breaking anything. My dad has a 6 horse Tohatsu that he uses with his Spindrift 22 and it gets him up to about 5 knots and I don't know if 6 horses is enough. I'm wanting to be able to outrun a storm that may happen to form in the bay, but as I said I don't want to break the transom off. What HP should I go with?
