33avs props w hp 500 efis
 

Had my new boat out, runs 78 on rev limiters hp500 efis, 28 pitch std bravo props w unknown history. Do these like labbed props, should i try labbed 30s or std 30s
700 feet above sea level, 75 degrees out

Love the new boat Smitty! Will you have it up at Hardy?

I ran labbed 30s on my 500HP carb'd boat for around 81 top end. Labbed 30s should spin close to the same RPM as non labbed 28s though, so in your case, not sure my experience is applicable.

Thanks, going to round up a lh 30 labbed to try with my rh 30 I have and may try a set of 30 non labbeds too. IF boat didnt like labbed props or something Iwould look for 30 non labs harder

Wellcraft has very good docs for older boats. They already did the testing. Look at 2001 33 AVS

I always got 81 MPH with my 500s running 28p four blades at 5250 RPMs.

Been seeing 77 or so in the humid 85 degree air with my 33avs, bought a set of used lab 30s last week, tried them today, saw 82 gps w full tank of gas and 4 passengers, later on we dropped off one passenger and were down to 3/4 tank of gas saw 83 gps, I havent even re-tuned the hp 500 efis yet, really liking the speed of this hull with so little power!

Labbed 30s are working on these hp 500s real well, solid 83 up stream at Hotboat and saw 84-85 on gps down stream w 1/4 tk of fuel, raised hp500 efi rev limiters to 5500 to get the 84/85 and still touches the rev limiter once in a while
