What kind of top end with the 555's to me more power is better, might be interested as well.

The 555's can spin the 32p bravo 1's to 5500 at 85 full of fuel with two people. It needs more prop.

That is 23% prop slippage as well, are they labbed props or stock.

Labbed. Came with the boat. It needs to be dialed in. I have not run it enough since the engines were completed.

set of stock 32,s would probably work best, it will bring the rs down a couple hundered but should help lower prop slip numbers. I also sent you a pm

I did not get a PM. Your mail is full.

What headers are those?

Yep - those are the ones. The ones in the boat have one fresh water season on them.
