Has anyone installed one of these kits on their 500? If so, what are the pros and the cons?

Thanks.

i would go with bob madara's kit first....he has a better camshaft and better cylinder heads..may cost a little more money but the better parts will out last the competitors..585-654-8583

That and there is MUCH much more than just bolting stuff on, you need comp change as well as fuel system upgrades.

For that reason, we don't offer a "kit". Everyone wants something different. Every boat is different and needs power and torque in different places. Everyone's budget is different. Etc. Etc. Etc.
