Does that steering ram stick out behind your exhaust when you trim it up?

Truck what pitch are you running now at the 5400RPMs. I have some good stuff props that will probably work as good or better.

You should have picked up some good hp. It sounds like Griz probably has some mph for you.

Have you seen what Last Real Texan has gotten out of his 27ZX? Your boat will actually get up on the pad if you can get it north of 80.

It does hook to the back of the bravo-1,I belive the exhaust is above and over.

Bill, I totally forgot to call you back. Was busy trying to swap boats and get mine back home. I told you that BIG GRIZZ would have something for you to try. If I were you I would try that FUSION that GRIZZ has. I'll give you a call in the am. Looks Good.

I thought it should be. The pics look misleading. I am having the exact same system put on my boat this week.
