Props for 46

[endeavor1]

Sax is right. -2 drives and 5 blades on a 46. My 02 was night and day different 4 blade to 5 blade and my 43 was same with /shorter drives. John P kept thinking I was crazy till he swapped out to -2 on his 46 and has never looked back since.

A really 6 awesome guy. Much better than the phuck head who calls himself cooler bitch

Any luck?

I pulled the spacers off and actually lost speed all around (mid range and top end). I haven't had a chance to get any measurements as to drive height yet but I will in the next couple weeks. I'll post what I find.

Any luck without spacers and 5 blades?

If that's the case, I'd seriously be questioning the HP your motors are making. Leak downs are in order IMO

Pressure check the inner coolers to ensure you aren't loosing boost there.

I was planning on doing that this winter anyway just to see what things looked like. I'll pressure test the inter coolers too while I'm at it.

Hope it's something simple for you to fix rather than a big mess. I remember those motors were torn down then being put back together when it was first listed for sale.

Not sure. Boat runs great and I've put 120 hours on the motors so they couldn't have done too bad a job with them.

Agreed, I doubt the engine itself is to blame but rather the procharger setup

 

[splashandburn]

Yah that's what I was thinking too although not sure what could be the issue. I'm making 5 lbs boost according to my gauges so where could that be going?

 

[endeavor1]

Where is pressure reading taken? Mine being carbed 500s was in the intake under the carb. 5lbs is what mine ran also. I spun 32s though. My 43 shouldnt differ that much if any from your 46. It blows me away that things got worse when you pulled the spacers. I run 26s now on NA motors and run 70 at least all the time loaded. I'm perplexed with that boat but I still like the paint job!! I'd try the following to see if anything stands out.

Compression test

Verify drive ratio is 1.5

Get a long straight edge and check hull for hook and drive height

If possible, weigh boat and trailer to make sure it isn't soggy.

 

[splashandburn]

Planning to do leak down test and dyno this winter. That should tell me alot.

 

[endeavor1]

^^^agreed

 

[splashandburn]

So I pressure tested one of the intercoolers today and it has a leak on the water side. Very small pinhole inside the heat exchanger. Goes from 20 psi to 10 in just over an hour.

 

[endeavor1]

Hmmm

 

[Ratickle]

Would that make that much of a difference in power?

Called Sax and he stated that the variance would lead to putting out the flame in the fire.... He's the Sax so I'd say he's qualified
