02 35' w/575's prop question
 

Just purchased a 2002 35' Lightning with 575's. All stock with 153 hours. Came factory with 34p. Have factory sheet. Reggie got 96mph on hot day no chop. I had it to 98mph 75 degree day with 1' chop gps. To say this boat is tricky to get on plane with the 34's is an understatement. Just awful. Put on labbed 32p. Very good to plane. 94mph 75 degrees 1' chop. Of course I am trying to make 100 mark. Do you prop Guru's think I can get there with Maximus props or do I need to raise x deminsion? Thanks in advance.

Herings would get you to the 100 mark. Raising the x would make it fly.

Listen to the man! Congrats on new boat... Was this one out of Kentucky?

Thanx for response Reggie. Where do I start on pitch with Herrings? What is the best way to raise the x? What do you think I can expect with either and/or both. Yes this is the boat from Louisville, Ky. The owner was telling the truth. The boat is as new.

Found my Performance Report. The X Dimension is 34"C x 18 1/4 x D.

1.35 lower gears & 28 pitch props will work too.

The x needs to go up & a set of 31 or 33 herings.

Ok. 2" imco 1.50 lowers and 31 or 33 herrings. 5 blade or 6? Good starting point? Thanks again for advice.

I have experienced all of that with my set up. I had standard lowers went to -2 imcos then -3 imcos had hydromotive 4 blades went to hyro 5's. Now running 31 p 6 blade herings @ 19 1/2 total x. From my experience at your x dimension, you're not going to go any faster with more blades. A labbed Bravo 1 prop is very close to a hering in performance when it is totally submerged with an x dimension like yours. 5 and 6 blades only come into play when your x dimension is above 19. I have a set of 30 pitch 6 blade herings and a set of 35 bravo 1 labbed props for sale. The worse props i have tried were the 5 blade maximus.

What gear ratio and what lower do you have? Are your rev limiters stock?
