Get a 32 hp Isuzu from Klassen Engines.
They supply a good steel exhaust manifold and have good prices.
Say your'e a fisherman. They deal mostly w fishermen.
I have one of their engines ..a 37 hp Mitsubishi.

easy rider for your help,,,,,,i have some ideas from other builders.
your advice it's one of my opccions ,beacause i have a kool keel
void's i could use a normal tractor motor,up to 40hp,but the capasity
kooling area will be no more then 30-32hp engine,the idea to use
kooling area insted of a radiator,my tug will be only for pleasure
no for working ,the gear box will be bery important as you mention
most regards CARLOS
