A little over 75 GPS with a four blade prop and 500 hp and I'm running it wrong? How so? In full race trim the F1 boats only ran 77-79 when light? And I can cruise 60 at 3 MPG with the Maximus, not sure how you are gonna get much more out of it. BTW, I think the Maximus was part of your performance problems, when I had it prop scanned there was over an inch pitch variation between the blades, it runs much cleaner now that it was trued up to an even 26 on all 5 blades.

Coen found an X that worked well and stuck with it ! The lack of trim reaction is from lack of HP . 800 with that same trim would make dramatic changes in the attitude . I'm not knocking the HP in Ted's boat either because it looks like he's getting killer MPG and running in the 70's is still a lot of fun

When I said light I mean low fuel and not much stuff, mine has stereo, porta pottie, cooler, etc, etc.I did go faster than 74...just not much. I had/have access to LOTS more power if I wanted it, but then I would get into drive issues so I left well enough alone. And gas mileage is a good thing

If I sell it we are looking at an Intrepid Center Console, just like everyone else with performance boats right now

Pretty sure mine is race layup too, Gary pretty much bought everything in the catalog

Has anyone had problems with reversion with their y2k. The owner I bought my boat from had lots of trouble with this. Has had to have the motor redone a few times due to this. The boats sit low in the back and with the swim platform and side supports coming out to the platform it makes a perfect trap for water when stoping or reversing or just waves while idling. He had to have the exhaust modified with a 4in extension on top of the thunder exhaust manifolds to increase the angle of decent going out thru the transom. The motor is a big cubic in 565 with a pretty large cam witch doesn't help matters. I am wanting to put my CMI sport tube headers on but don't know if it would be a bad decision and possibly make the reversion situation worse.

Yes, ideally you should run dry exhaust with that engine and I added flappers on my exhaust pipes to help some. On one occasion it gulped water in reverse and almost died, a little throttle blip cleared it.

I'm running rubber flappers on the outside too. I had internal flappers but they made an annoying rattling sound so I took them out. I'm always real careful coming off plane.
Oh, and my boat doesn't require a lot of trim either. About "3" on the indicator is my sweet spot. I have ITS though, not sure how that factors in.
