fastest stock 50hp motor to buy

[keakar]

I hear a lot of talk about tohatsu motors being very fast but the 4 strokes weight the same as the 2 strokes and are both models equally as fast? also which one is better and why.

also are there other motors that are just as fast or for that matter just better motors overall if not as fast?

I think I need a new motor and wanted to know where to begin searching for a replacement for a 17x52 flatboard motor in the 50hp size (max rated) and I want to get over 30mph top end, hopefully 35-40mph

as I understand it the Nissan/tohatsu motors are the same motors being branded and sold under the Honda badge
