How manny rpm would you pick up wen u put on a -2 lower on a single 30 V bottom with a pad 6500 lb boat 502 500hp 1.5 gear ratio bravo 4 blade prop lower is about 4 inches below pad now. TIA

My guess is you won't even be able to get on plane with a -2 lower and Bravo prop.

It has a bravo now plane s off without even touching tabs!!!!

what rpm are you turning now ? current prop pitch

5800 24 bravo I know I need more prop

Im surprised its still together..............id get the revs down around 5200 5300.........maybe a 28-30 pitch, then address the drive issue

Going from 4" below the bottom to 2" below is a huge change. Most single engine V's are set up in the 3-5" below range.

I agree with Griff. You can install an IMCO SC -2 lower but you'll probably end up with a 1-1.5 inch spacer. I do like the IMCO SC lowers though, very little drag.

Thanks guys ill let u know how it worked in June!!!!

i put a 2 inch shorter sportmaster on our 25 foot thunder and lost the fun of overtrimming and winding it to the moon nothing sounds like a na bigblock wound up to 7000rpm it still slides on plane with no effort, it was more fun with it deep
