Look for a -2 shortie drive. You can get the case and have the gears swapped.

where is the cheapest place for the -2 case? I also tried the two props and had big problems with both. One was a three blade 21 that was reworked and stamped 23 it also had the flare cut off and was satin finished. the boat would barely come up on plane and hit rev limiter pretty hard with less top speed. I had to turn around and swap it out then i put on the 23 converted to a 25 3 blade and lost a few mph. it performed a lot better (than the 23) but would still spin out and lose grip in turns. it pulled my buddy on a knee board pretty well but still hit rev limiter. The boat did 52mph gps with the well used 21p mirage plus that came on it. I have hit the limiter with that and gotten airborn . it pulls the skiers fine but i want a bit more top end. What do I need to do next? the other props both did mid 40s i didnt even write it all down, I was pretty upset. Thanks for your help. I need it.
Also with 7 people and big coolers the 232 would only do about 42-43 pegged out. It was a slow poker run. Thanks gabaja242 for waiting on us.

Not that it's much help, but my 252 will do 62-63 on the dream-o-meter turning a labbed 23. I also have about 400 hp's at the crank on a carb'd 454. I would say that when it comes down to it, you just need more horsepower.

Like someone else said, fix the little stuff 1st. Like in drag racing the speed is in the setup.
I would send the propeller to Brett @ Bblades in Princeton, Wi. When you get the bottom paint off, I'd hit it with something more aggressive than the 1000 grit. Get it off there then touch it up with the 1000. Leave the back 4' rough (1000 grit rough). The rest of the hull can be shined up to look pretty.
Clean up the skeg & the cav plate.
Verify the tachometer is reading correct & don't be afraid to spin that thing upwards of 5k. They will handle it just fine, just don't be a retard about it because it won't live all day spining 5 grand. 4600 to 4800 would be where I'd shoot for. Test it how you will use it. Don't do your testing with fumes in the tank & one bottle of water in the cup holder. Load it down like it will be used. Don't be afraid to ask!

I hear the rev limiter. What is it set at? Looks like 4800+

warrantykiller

rev limiter stock setting?

Did you ever have an update to this warrantykiller?

I just got my 232 with the stock 7.4/300 carb motor. It has a 21p mirage+ that looks like its labbed. I am turning 4800rpms and pushing about 54mph, though i have not done any runs by myself with low fuel. That's always been with 2 other people in the boat.

My problem is I get bad porpoising whenever I trim up more than just a tad. I guess I need to see where on my meter is parallel so I can determine if I still have the drive tucked or not when it starts to porpoise.

I'm thinking about getting a B1 4 blade to try because from what I understand porpoising is from having too much bow lift without the power to keep it up there. So the B1 should have less bow lift and keep me from getting up so high and falling off.

Either that or maybe I need MORE bow lift so it can keep it up? In which case I could get some cup added to this mirage+?

jeffswav

A double cup (baja cup) would help.

jeffsway you are saying the 2nd notion that maybe i need more lift to keep the bow up will stop it from porpoising so much?

jeffswav

It helped mine, lowered prop slip also.
