Candyman, You must be saying that fountain raised the motor first ,then used the top hole in the stellings box. Yes mine are stellings. But if I put mine in the top hole that will put the drive lower in the water. It will lower the ext box. The bolts are in the bottom hole now and I can not trim the drive with out them hitting the swimplatform. and with the drives against the platform at 5200 there is no rooster at all. I think this is slowing the boat .??????????????

I checked the drive height tonight, they are 4inches from the bottom of the boat to the center of the prop shaft. Does anyone know what this should be with boxes?

I will be posting before & after results on my 35 going from stock bravo drive to -2 sportmaster lowers - going to run same props (28b1s) & borrow a set of 30's - hopefully pick up some MPH

That would be great. What power do you have.

500hp's w/upgrades

If we get the rain that is due , you will not be able to test. I hope they work out for you.

they are bolted on & ready to go - just waiting for the weather to co-operate

On a SSM IV or V, my prop shafts are 1" below the bottom of the hull. That's with Merc 12" boxes.
