the merc manifolds will need to be replaced with headers or a good aftermarket manifold setup,the computer will also need to be reprogramed.it starts to get expensive before you spend a cent on the camshaft itself.

I've built a lot of drag motors but not boat motors I've noticed that marine headers are pretty pricey anyway around that? How do I go about tuning the computer does it have to be sent out or is there some sort of off the shelf tuning available? Thank you
