Put my 210 LXI with the 650hp DirtyMax up on eBay this week. Summer is over and it's time to get serious about restoring the 38' Cat.

So if ya know anyone looking for a super clean 80mph open bow that gets amazing fuel mileage, point them here.

Bad Ass Boat! What level of Bio do you run in the boat, do you run B100 or a blended down version like B20?

Are the manifolds and up pipes not water cooled?

dang,,how do you get a bravo to live behind 1250ftlb of torque?

I typically run about a B50-60 blend, same as the wife's E320 prefers. Runs fine on B100, like any modern diesel, but you lose about 10% power and 4-5mph of top end.

Being the first Dmax boat rigging, there wasn't any cooled manifolds available. So they covered the manifolds and up-pipes in Coast Guard tested "Inconel" gel filled shields. Expensive material, but you can lay your hands on them any time ya want. From turbo out it's water cooled SS. So when I upgraded the manifolds and pipes, I wrapped everything head to turbo pedestal under those shields. Dropped engine compartment temps a good bit. One company now makes water cooled manifolds and up pipes for the Duramax.

The Bravo XR lives because the boat is only 4500lbs and max input speed is 4000R's. Output shaft is IMCO, was replace at like 5hrs I'm told. Respecting it helps too, no wide open hole shots or flying it out of the water.

I am looking for the marine parts to repower with a Duramax but nothing shows up on a google.

With that kind of power in that size boat, how are you not getting frequent flier miles?

Very shallow dead rise, and a wife with lower back problems equals no high jumping. Typically it's all river boating, however she has crossed Lake Erie and Lake Ontario, once into head seas of 3 footers for 20 miles. I was impressed that day, she got big air multiple times.

im MartinB; there is not much out there marine related so far, everything is pretty much custom builds with only about 6 boats being rigged Dmax that I am aware of..
