Repowering 18' Potter

[JayN]

Hi Boca, if it were my boat, I would go with a motor in the 115HP range, maybe a little bigger. like up to 150HP. It's nice to have the extra power, in case you need to carry extra weight, like dive gear, big cooler, or extra people. You don't need to run WOT all the time, and when you do it should get up and go. I have a 1971 20' CC with a Mercury 225, 25" shaft, 90 gallons of fuel under deck, and I can cruise all day between 3200 and 4000 RPM's all day long depending on the load I'm carrying. Once or twice a month I go out into the Gulfstream and collect 110 gals. of salt water, so I can do a water change in my reef tank, and this is when the larger motor really preforms to its max. Good luck with whatever size motor you decide on, but I always believe, go with the biggest motor your boat can handle, you never now when you will need it.
