What prop? What was your best MPH before?
Can I have some of your pressure? I'm still fighting low pressure on one engine. I'm gonna change back to the plastic pump on that engine and see what it does. While I'm at it I'm gonna try pulling water from the drive and ditch the through hulls.

great way to pressure test all your cooling

17x30 16* boat ran real good handled good. I have a real safe tune in the motors right now. Set up On the fat side for cool weather should be able to pull another 3-400 rpm. More concerned about cruise speed at 42-4500. Real happy with the #'s

It's all good I run steel cometrics with arp studs.

I get 8, 10 psi all the time w stock merc pumps pulling from the drives. I even have the coolers being fed off the same system.

If that boat went 90 before. It's gonna go 99 when he is done with it

Update? Anything new??

Is the pick-up trimmed down yet? any new news?

Reggie took boat out this morning for testing. Bracket on engine hatch cover decided to go south. needless to say, the rescue and recover mission for the engine hatch was a success.:eekdrop:

I bet that was a holey shyt moment. look back and seeing that flying thru the air!
