Ah the infamous Perkins. The only engine that has been rated as 30 hp, 45 hp, 50 hp, depending on how big the boat it is installed in. Don't hope for more than 30 hp, which is plenty for your boat. The alternator bracket is inherently weak on that engine and fractures with great regularity. Have one built from stainless steel and you should forgo any future fractures.
I actually do have a great boat hauler. His name is Tom Wagner (
