Performance Zapcat with a 4-stroke

What would be the performance of a Zapcat with a 4-stroke engine, a Honda BF50 (92 kg) for example.

I think in America they race a equilivant class to zapcats with honda 45hp outboards, so performance with the 50 must be pretty good.

I'm sure it was 45hp, though doesn't seem honda make it anymore... Maybe its just avaliable in the US.

It wont be as lively as with the tohatsu 50, but it would still be good fun. The only problem is if you flip it, starting a 4 stroke again would be much more difficult than the 2 stroke.

Edit: I think I saw a video and website racing 'dux' boats with the hondas, but I'm not so sure now, was I dreaming???

I cant see why it would perform just as well at top end speed as the tohatsu 50hp. It would be a nice engine to have on the back for leisure use

I think I would pay special attention to the difference in weights of the two engines!

Might also be worth considering what happens if you flip the zapcat. A normal 2 stroke is going to be a lot happier being upside down than a 4 stroke....

Seems to be a popular consensus of opinion.

I think the weight issue would be quite important - Zapcats are really all about power to weight, and correct me if I'm wrong but I believe that Tohatsu 50 is the lightest in it's class?

The only reason i should buy a 4-stroke should be te better fuel use.
Isnt the Tohatsu 50 2-stroke using 15ltr/hr?
