I had a chance to run it tonight.
As I guessed, it is over propped. It wouldn't pull 'em past 5500
which was somewhere around 95mph.
I am going to look for a set of 4 blade cleavers in a 32 or 34 for my next run.
My gaurdian came on twice tonight at 5500rpm for a overheating sensor. This is a new issue. I assume it's because of the increased load the 34 Bravo's were putting on the motors.
My water pressure seems very low, usually around 5-7psi. Anybody with experience with 300XS's and water pressure? I am told 300x motors should never get under 15psi. 300XS the same? I may try lowering the motors a 1/4 inch.

During a high speed run, one of the compressors came apart (it seems that it was assembled without any loctite) and I am having it replaced under warranty. I hope to be testing next weekend again.
Nice looking boat you gotĄĄ good luck....

I have a set of 300 XS on my 28 skater, and I am still struggling to get it propped right. As far as the guardian system, it will come on when water pressure hits below 12 psi, so try to keep 12-15 as a minimum. It will also beep at 6400 rpm, if RPMīs donīt drop within 5 seconds, the guardian will kick in and drop your rpmīs. The engines are well protected by the guardian system. I am running 34 X 14.5 3 blade labbed cleavers for a top speed of 107 mph at 6350 rpmīs but ocassionally hit the rev limiter. I have a set of 36 X 15 on the way to test.

I lowered the motors about a 1/4 inch today. Now I have 7-15psi. I have to re-test with another set of props to see if I lost any top end.
