I've got a complete IMCO Extension box, Complete gimbal and steering for SCX for sale. Would be a great deal for someone. Would be able to bolt the boxes on and go. Pm if anyone needs this.

Switching to #6's or -4's??

700hp 575's

Not switching drives, just bought quad ram steering complete set up.... The boat does not need #6 weight in the transom.... The drives themselves will be kept, just everything in front of them. I've got some work to do.

Do the -4 imco scx have a water pickup built into the case or you guys installing the external pickups for better water flow

External

And the drives all feed this one strainer that feeds both motors.

Is anybody picking up speed w these things vs bravos.

I picked up 1.5 MPH

The -4 has a water PU but IMCO said it's only good for drive shower water.
I had water pressure problems with my initial through hull setups so I ditched them and tried getting water from the drives only. As I started throttling to get on plane water pressure would climb. As soon as the boat started to nose over the water pressure dropped to 0 PSI.
I kept playing with the through hulls. The problem ended up being the Hardin SS raw water pumps. All I can see is that the impeller cavity is a bit smaller than on the plastic housings.
