way to high....is this thing new.....WOW.....imco offers spacers that can lower your X.....suggest you start with a 2- 3 inch,or isnt that imco box adjustable,think you can lower the gimbal housing but your gonna have to lower the motor mts

Try a five blade. Might get you going till you can figure out the best wat to lower the X.

I agree with Offshore Addiction. You need to bring that x dimension down. Any will help but it sounds like you need three inches to get to the keel line. If you are moderately powered you probably should be even below that. Does your boat have a notch on the transom just in front of the drive on the center sponson? If so you need to measure from the height of the bottom of the boat not the notch.

post a picture!!!

did you buy the boat new? Or did the previous owner put the extension box on?

I bought the boat as a dealer demo supposely,It has a merc 600 sc with chiller.I dont see no notch on the center sponson,so do you think the spacer will help orhoould i do any help is greatly appreciated.

I have a ChrisCat drives are about 1/2 in up try some larger diaminter props if you can find some. At 3in up I bet you have a hell of a time getting on plane. Take off slow ease in to the gas to get a little speed then when the prop brakes loose take it up to about 6k for a few seconds then back out of the gas to around 3k or so and see if it bites and takes off it that doesent work stand on the gas untill it takes off. :D

supreman, why not drop warlock an email and see if they can't help you sort it out. I'll bet they already know the answer.
