Okay, I would like to compile a list, only because it matters to me and perhaps others. If you would be so kind (inboards only)

1. Max RPM at Wide Open Throttle
2. Max Speed at Wide Open Throttle
3. Year of Boat
4. Manf. & Model
5. Engine
6. Transmission gear ratio
7. Prop dimensions (# of blades and pitch)
8. Octane of fuel
9. Normal operating Elevation
10. Anything else you want to add that may make performance different

It will be interesting to see how boats with the same setup compare.

Water temperature definately makes a difference in performance. I always check for performance in the spring in cold/cool water, for comparison purposes from year to year. 2 persons onboard, full tank of gas and gear.
Hope this helps!

Switched props to 13.7 X 17 and got 5400 (rev limiter and 42 mph-but a larger pitch prop will be the key)

Clearly the boat is overpropped as it cannot get to max RPM's wth the 22, next spring we are going to try a 19.5 pitch from OJ and also try prop from Acme ... the original OEM prop was SS but cracked during the first season and was replaced on warranty with the 22 pitch OJ

10. Anything else you want to add that may make performance different - 400 Ft Lbs tork from 1100 to 6000 RPM, 420 HP at 4200 RPM. Balanced and ready for a blower (Rods are rated at 750 HP and Stainless non welded valves) but I like it the way it is, heck 50 MPH and you hit a big wake - you better have your hand on the throttle and back off. I've allready got too many Gelcoat spider webs now.

I'm using straight exaust pipe, 4" OD all the way. I lifted my box 1/2 inch in the front (closest to the tow bar) eventually I will lift the entire box 1/2" front to back. This winter I am going to make SS exaust primary pipe from the manifold to the exist straight pipe, install another back flow device inside just before the inserts and couple it all togather with the existing rubber (got to have some flex), I'm going 'down under' style.

I have the original prop 3 blade 14" was modified from 18 to 20 pitch. I could get Red Line 6K RPM. I changed it to a 14.5x22 4 blade it was a little sluggist out of the hole and could only get about 4.3K RPM. OJ sent me a new prop and I'm thinking I like it. It is a 14"x19.5 4 blade CNC. I get higher RPM, better econonmy and it's still strong on the take off. My son was pulling my big fat $## up and he said he hit 4K. As soon as I got up I went head over heals. I guess he should have backed off a little when I surfaced. Props, Props, Props .... I think the one I have now needs to have a little more cup, say 20 or 21, but the 22 would not get above 4300 RPM and it seemed slugish. I still haven't seen +50 MPH no matter, it seems like that is all she'll do no matter what prop. That little 3 blade 14x20 SS that was modified would do some weird stuff. You could be going 35 MPH turn make a 180 turn and she was strong, jumping out of the water. Maybe that's why when I purchaced the boat it had a blown engine. 6K was nothing and I blue'd the SS prop the first day. Cavatation.

We seak power, no cavation except under extream load, no redline RPMS and performance. This has been fun.

Me too. I just called the dealer where it's being winterized at this very moment. Tech says the answer is 3 blade 14 pitch. Now I know.

When new, I got 48.9mph on PP. For some reason it has dropped off, we're now at 217hrs. Maybe I need to wax the bottom.:D

Theoretically, the 2002 ProStars will get a bit more on the top because they didn't start hooking the hulls on production models until 2003 (first hooked hulls were 2002 TT boats).

Is gear reduction standard on the larger boats, for some reason I thought that it was, but I've been wrong before? I'm pretty sure you have the 1.5:1 ("powerslot") transmission.

you're right x-45 come standard with 1.56:1 tranny, no options on tranny, and the powerslot tranny ratio is 1.26:1

I didn't read all of the responses, but I did read someone saying they thier owners manual suggest mid-grade gas, but they run 93 octane. You should NEVER run a higher, or lower grade than recommended. It causes a loss in performance, and could damage your engine. You don't get better mileage, or a cleaner burn, only LOWER performance, and a thinner wallet.

I think your WOT is too low for your engine. According to Indmar you should prop your boat so that the WOT RPMs are between 4600 and 5200 rpms. Based on the information you provided you are actually lugging your engine which is not good for it. You will also get an improved hole shot most likely if you reprop it. Your top end might change, but it is hard to say.

That seems like a lot of RPM for that motor. Have you tried a 14 X 16? Would think with a 16 the RPM would be reduced and should pick up some top end.

You know, I don't know what size the prop is... I assumed it was original but the previous owner did give me two props....? I'll have to check it out..

Max #s seem a little low but I don't think it's enough to think there's a problem? I was thinking about going to an Acme 543 due to high elevation but the 1180' #s tell me that its probably not an elevation issue?

9. Normal operating Elevation ~800
10. Anything else you want to add that may make performance different Upgraded to GT40 heads in the summer, gained about 4 mph. I tried a tank of 91 octane once because it has no ethanol, boat actually ran a bit worse @ idle, harder to start, not unexpected for an engine designed to run on lower octane. I stay away from the mid grade 89, as that has much higher ethanol in my area.

It will be interesting to see how boats with the same setup compare.[/QUOTE]
