This is interesting. What went so wrong that you smoked BOTH motors on the same trip out ...?

Lifters on both motors. Broke the bottom off on two of them and metal started making its way around.

It was strange to see regular duty (smallish) lifters in the Big Chief heads........alot of things Sterling does is a little different.

The boat sat over a year before I purchased it but the motors claimed to have only 15hrs on them.

Been there, done that. Not sure they are where they once were in the non-racing department.

So Apache Pete how fast do you think she would " allez vite " go?
Tom Earhart

She has enough power to run 100+ Tom.

Might want to read the bold print above tom's question.

Tom builds a 1500 HP 572 Twin-turbo motor. He's got one in a 30' Checkmate that runs close to 120. I declined a ride offered just yesterday!

With the current rebuilt Zul motors, I'd guess the old resin bucket 41 Apache could hit 100. Add dry-sump 6's and some modern props, perhaps 107.

Add a pair of Tom's motors, maybe 125-130?

I would NOT want to be onboard at that speed! Much over 100 is asking for trouble, IMO.

But you would be up to speed and then back to zero so fast you would even have time to worry

It's Smooth..................very Smooth!

Maybe we should just put a set of my 557 cu.in PSI supercharged engines in the boat . = 1700 HP each x 2 = 3400 HP and she what she will do.

and just how long would that take? 2 weeks... just kidding Dean...
