Outboard size for 20ft sailboat
Just put my boat in the water (1967 bristol corinthian, 19.5ft, 2,800lb displacement).
I currently am using a 5hp tohatsu that actually used to be on a 10ft inflatable dingy (the shaft is not long). It works, as it sits in a motor well inside the cockpit which opens essentially 10inches or so from the water line.
Issue is it is a little to big and rubs up against the back of the cockpit. This not only makes the boat vibrate, but makes scratch marks on the fiberglass. Also is cumbersome to lift out and stow while the sail is up.
I only am using the motor to get in and out of the dock, once out the sail goes up immediately.
My question is if a 2.5 hp o/b would be to small or weak to push the boat along or if I really need to go to a 3 or 4 hp range.
I am looking at a mercury 2.5 hp long shaft.
