Upgrade 2 stroke .46Os Fx to 4 stroke

I'm thinking of upgrading the engine on my Nexstar from the factory 46fx to a 4 stroke. Any benefits other than reliability and sound? Also what size should I get?

look in in the .70 - .82 range. it will give you a nice performance boost...

Undoubtedly, you will need a longer engine mount to clear the rear mounted carb...

The sooner you fall behind, the more time you will have to catch up.

I agree with Nony. A Saito .72 would be a perfect four stroke replacement for the .46 two stroke.

A four stroke, because of the higher low end torque can swing a larger prop. Where your probably using an 11"X 6 or 7 prop with the two stroke, you can swing a 13"X 6 or 8 with the four stroker!

Relyability, power and sound...what more do you need? Besides, four strokes look nicer too!
