I've been told this before, by Procharger and others, but never got around to it. My procharger belt was slipping (new belt this winter) so I tightened it yesterday....WOW what a difference !! I'm getting 7 lbs. of boost (up from 5 lbs) for the first time. For the first time since I've owned the boat, it took off like a rocket...literally ! I don't have any way of knowing how tight it should be or how to measure belt tension but, man, what a difference !! I'm tempted to give it a few more turns with the wrench but don't want to snap the damn thing. Food for thought...

I only had a minute or two to take it for a test run and ran out of time and water (ran into a no-wake zone) but it rocketed to 70 way faster than it ever had before...When I get a calm day and more time I'm going to run it again and I'll let you know what I get out of it.
It is a 7 psi system but I never knew that. I bought the boat used with the Procharger already (poorly) installed. I know a lot about boats and Mercruiser motors but nothing about Prochargers. It has the Procharger competition fuel system which, I've come to find out, is a necessity for the 7 psi system.
I'll keep you guys posted, thanks for the replies !!

Is it a 8 rib or 12 rib drive? I started out with a 8 rib drive on my m-3 on my baja 272 and the belt had to be ungodly tight or the boost wasn't consistent,especially with any upper pulley under 4.250". I have since upgraded to 12 rib drive,doesn't have to be nearly as tight but still pretty tight,if your finding ANY belt dust it is slipping. I have wiped out a couple idler tensioner pulley bearings over the 300 plus hours I have been running a procharger but I hear they have a upgraded bearing,I just bought one locally last time because I wanted boat back together the next day,Smitty
