I am looking for little help on setup 2006 42 ex with standard bottom bravo XR's. Right now my prop shaft heights are at 4" below bottom measuring straight in front of drives to hull. I am getting high slip numbers and difficult to plane with certain props. My boat was built with different power and -2" shorty sport masters and 6 blade Herings from factory but previous owner put standard bottom and length bravos on. I have read that standard bottom bravos like to run little deeper for trim leverage on heavy boats. My thought is to try 1" spacers but was wondering what other guys are running for drive heights on 42 ex?

Actually its 3" below hull straight in front of drive.

In reality here what you need to do is find your "X" dimension, where it was when it left the factory, and the move forward from there.

I put 2" spacers on BZs 2006 42 EX 525 XR setup and actually gained MPH and it doesn't take 5 miles to get on plane anymore

Spacers are ordered and will be testing this weekend. Obnoxus did you try 1" spacers? I talked with BZ and he was not sure of prop shaft height with 2" spacers but said it works good now. I am going start with 1" and have 2" as backup. A friend of mine just bought a 42 that is 1" deeper in water prop shafts and his numbers are pretty good with slip and mph with bravo props.

NO,,,, we found 2" used first and it made a huge difference so we left it alone.

I have a set of 1" sitting here now that I will swap out sooner or later to see what happens.

You have a few MPH on us so that makes me want to drop to the 1 " even more now

525's
