wanting to super charge 525s
 

:asskiss:what is the best option for super charging 525s and make them live with the most horse power?

I am guessing 525efi Merc's, my 2 cents would be Whipple, do a post in GD many hve done them with very happy results.

what is gd?

GD = General Discussion, and the 525 3.3 whipple is a great way to go, same thing I am doing over the winter to mine with upgrading the motors to 509's. Good luck with your project.

GD= General Discussion, I think a guy had a 38 Hustler whippeled 525efi's got 780 on dyno, but I wouldn't push them that far.:evilb:

Drives?
 

You need to consider your drives as well. More HP is a great thing as long as it doesn't destroy other parts.

Alot of guys make a living rebuilding blown drives. Same guys that gave you more power to start with.

Sell the boat and get one with 700's and #6's

Agree.....that amount of HP will kill your drives, sooner or later, and as we all know that's big $$$$$.

It really depends on the boats length and weight - not just the amount of HP. You can probably get away with doing 750 HP+ in a 35 Fountain or smaller with twins, but try that on a 38 Top Gun and you'll be poping drives left and right.

whipple it!
