It depends on the weight of your boat, and your prop slip.

The less the weight, and the higher the slip, the longer the drive will live.

Very true, I have a 13K pound boat with a pair of 525SC's and just lost my first drive at 250 hrs (basically my fault though) i do attest the life of the drives so far to a fair amount of prop slip and the boat still touches in the high seventies, i dont baby it either. I asked a prop guy once about my drives and he also verified the right amount of prop slip helps keep them alive.


750 hp though? . . . dont know about that one

I have a 4800# boat that has a 600sci in it, and my IMCO SC drive is living at 5.5% slip. I am very easy on it. I am about to step up the hp to about 750, and was told by the outdrive guru's to not let my slip get below 10%, and that I should aim at 12%+ just to be safe.

We shall see,

Chris

Thanks guys for all the helpful info.... after hearing all of you, I have made the choice to look for another boat with hopefully less repairs (one never knows though!).:rolleyes:

There are two guys that I know on the Bay both with 700hp 100 mph 42 Fountains with Xrs or beefier & a 95 mph 675hp 37' OL Stiletto.
They all keep spare drives in stock, as well as plenty of full coolers for that inevitable 7 mph limp home.
I also had bad luck running over 700hp with beefed up billet Max Worx drives running high ratio and small props in our Kevlar Topgun.
I see guys with even more power in smaller boats doing pretty well with beefed up Bravo based drives.
The guys I know never see more than 20 or so hrs at a time running a larger rig with that kind of hp.
Good Luck!

Smart Move, My friend just received a 35zr donzi with twin 525s.The boat runs in the 90s and looks like a 9+. Great set up on bravos and will make many trips with a turn Key put gas and go. Good luck :D
Also the price was very right!!

JayFan 01-31-2009 09:05 PM

Sounds nice..HotPursuit, got any pics?

JayFan 02-01-2009 08:35 PM

Ok...I need to adjust my thread! What if the engines are 650's and have IMCO's not Bravo's......

Does this change anyone's minds, or opinions, interested to know.
