Re: Tanaka 2hp
Hi PScrabber. They were sold ounder many different names such as Gamesfisher, Tanaka, and others. You'll hear a wide variety of opinions on these little motors. They're essentially weed eaters witha prop.
Pros: Very Common, Cheap, fairly reliable, air cooled (so no impleller to change or worry about), no neutral or reverse gears so they have very simple gears any one can fix, they're very light weight, and get great gas economy.
Cons: Probably cost more to fix than they're worth (assuming you can find parts), loud (think weed eater), not as smooth as a larger motor, not as sturdy as a larger motor.
I have a 3 hp Gamefisher (Tanaka) and it has served me well over the years. I've taken it in fresh/salt water and every where in between. However, when/if it dies that will prbably be the end of her as new parts are worth more than the motor. If you don't mind a little extra noise and vibration, I say go for it. They're scrappy little motors and fun/easy to work on and would make a fun winter project, but don't be surprised if new parts aren't cheap or easy to come by. If you're lucky you might be able to find a parts motor. Just an opinion.
P.S.
I have the owner's manual so let me know if you wnat me to send you a copy.
