I have a 4hp 4stroke Merc. 2002. Heard it's possible to convert it to 6hp by changing the carb. Is that a fact? Is it as easy as that?
Cheers...........Pete

Pete, think about it. Is changing the carb going to give you a 50% increase in power?

Of course it is . . .a myth.

Pete, I believe the 6hp was a 2 cylinder, so you may be out of luck there. I can say that we have never done that conversion.

Lately, we have done many 4hp to 6hp conversions on the Tohatsu based motors. The hot setup is the 4hp with the built in tank with the factory approved conversion to 6hp via the carb alone.
