You will have to contact Dustin directly for pricing.

This is an easy addition.

With your #6 drives... I would think this would be a no-brainer.

Mark knows his stuff for sure!

Merc says that over 50 psi at WOT is too much water pressure.

Every boat is different. The Fountain factory was very helpful even out of warranty.

It is a lot eaiser to go with more boost than changing the cam, but I will probably do cams, pushrods, lifters, springs and head gaskets at 250.
