I'd rather stay home than break a drive or engine!

I have heard of and tried different size pitchs on outers and centers. The problem with outeres being so high is when you turn boat they will cavitate. I went to four blades and problem was non existent.
25" centers would be a lot easier to find.
I want to keep the top of engine cowlings as close to even with each other as possible.
Here's a pict of a new Homeland Security Midnight.

Enforcer2;
I'm going to ditto the info from MOBILEMERCMAN and add this... Ultimately you will check your height by doing your slip calulation. If your percentage slip is much greater than about 15%, than you know to lower that motor.
On a VEE I would try to get the props as close together as possible. I remember when people used to angle the motors on the transom to get them closer at the prop.
