Default Evinrude 437cc

Hi group

I built a Ragwing RW-6 and was thinking of using 1972 Evinrude 437cc engine,
rebuilt of course, from a Evinrude TW-30-Q snowmobile. It's a nice looking
twin apposed cylinders But I think might only be 30hp.

Does anyone know anything about this engine, and can the hp be increased
safely.

I also have a polaris 340cc but would like to get closer to 40 hp.also
considering 1/2 VW.

Any help would be appreciated. Thanks Joe
