I had posted a poll about a K&B .40 inboard an no one has replied. What other companies make an affordable .40 engine. I would by the o.s cause that what i usawlly use in my planes, but this is going ina boat an i dont wanna spend that mcuh money on an engine. Any sugestions?? please help!!!!

Mega Tech , and Leo both are the same motor and are very good sport engines. Do a search for lthem. If you can find them, HP, HB, and Webra are also good sport 40 motors too, but hard to find.

O.S. and K&B have good marine engines for the money. The marine engines cost a little more than plan engines, but a marine engine is made for boats and plane engines are made for planes. A plane engine will work but no where near as well as a marine.

You need water cooling for a boat, the marine engines have a water-cooled head that is fed water from a pickup tube in the stern and exhausts out the side or stern. Electric motors are a lot cleaner and easier to use and can be quite inexpensive. You can also water cool an electric motor.

Electric motors can run under water. Thats another plus.
