-3 modification who can do this
 

I need to have the cavitation plates on my IMCO SC drives modified to run -3 lowers. Does anyone know who can do this?

WOW - your going all the way to -3. That is a serious change in prop height.

You trying to beat me in prop shaft height?

Ha- I was running -2 last season and I was still deep. I'm pretty sure I can pull off -3's, that will put my shafts 4.5" below the hull. I think you still have me beat!

WOW they were deep. That extra inch should make a noticeable change.

Yes they were, I started out at 7.5" below. Last year with the -2's I could still run Mirage props without any issues getting on plane. In big waves I had to work the throttles, but thats it. I only tested the Mirages, I never left them on. I ran Bravo's all summer and never once blew out the props. That told me it time to go higher!

Did you use a lot less trim with the shorter drives?

For the most part yes, Past 6 i really didn't notice any speed gain. It would have been nice to have run the boat with the old motors and the new drive set up to see what the real gains were, but that wasn't really realistic. I really think this extra 1" will make a difference, my drives were DEEP, which is one reason why I think these boats are not that fast with big power. Once I get the drive height correct I think I will see a bigger improvement in speed.

The Bravo Shop can do it.

Thanks! I'll give them a call.
