I ran mine 102 miles Monday, water pressure was 10-13 before the small ramps, now it is 30 plus psi. We ran 46miles to the destination in 31 minutes, thru a lot of turns, then into a big lake. I raised the engines up more now for the next run on Saturday on the Suwannee river, with the Scream and Fly guys, the Spring Thaw. There is a lot of turns on the Suwannee River also.

Kirk, Are you seeing differential water pressures from port to starboard engines while in high speed turns (loosing water pressure)? I was getting temp. alarms while in sharp turns at my "skinny" lake. I added a water balancing hose connecting the engines thru the adaptor plates and now have very close to equal water pressure in both! Just wondering has you experience.

Curious how you ran the balancing hose, any pic's?

I drilled and tapped the Adaptor Plate with 1/2" NTP to JIC barbed fittings (-10) and ran the hose thru the rigging tubes to each engine. [ATTACH=CONFIG]551793[/ATTACH]

My X's are already plumbed for this balancing hose as the 32 had thru-hull pick-ups. I thought it was a good idea to keep them for pressure balancing but It was recommended to me by a pro that I should keep the two cooling systems isolated from one another.

I assume if you have the two exhaust adapter plates connected there must be a check valve (one way) in line somewhere on each motor, otherwise if one motor were running it would be dumping pressure in to the non running motor. But then a check valve would cancel out the ability for the two to balance.

I really like the balancing idea for obvious reasons, I guess someone just needs to explain how to make it all work.

FP, No check valve. I don't usually run on one motor unless I broke something, then it is "idle time". At idle and up to 1800RMP, I have had no pressure issues on one motor. That said, I can now make 80+ MPH turns w/o watching my temps climb and hearing that damn alarm! It was also suggested to me by a pro cat racer to add them. So I guess there are different opinions... imagine that!

OK so pro's con's on doing that and using a slosh tank fed from in hull pickups to feed all motors leaving the lowers alone vs tapping the lowers like DR did?

I'd really like to add hull pickups to mine so I can get the motors to where I know they ought to be but don't want to tap the lowers if I don't have to...

Check valve will not work. Water has to move both ways as it changes whether your turning right or left.
