Water or air cooled 7.5 hp?

[Bearcamp]

I have a chance to purchase an air cooled 7.5 hp Gamefisher. re they better than the water or is it just the oppisite? I'll be putting it on a 14 ft. jon boat. Does anybody think I'll have any problems. Do the air cooled seem to work OK and what are the negatives about them?<br />Thanks people.

Most of those air cooled moptors still had a water pump. It pumps water up through the middle section of the motor to cool off the exhaust gasses.

Howdy, Bearcamp.<br /><br />Air cooled 2 stroke engines run hotter than water cooled, so they require a different oil, and more of it. They are also noisier and lighter.<br /><br />You would need to use chain saw oil, not outboard oil.<br /><br />The air cooled outboards I have worked on did not have FNR gears. They were very basic engines. Single cylinder engines just wont idle down like twins.<br /><br />Bottom line? Light, cheap, no-frills, noisy and smoky. Not my choice in a small outboard.<br /><br />Good luck.
