Is it a transom mount pick-up? If it is, file it down in small increments until you get the water pressure you want.

What he said ,,,,he knows more then me anyways !!!!!

A picture of your waterpickup would be nice though ?!

Mine is at the transom and sticks out about 3/16 of an inch ,getting around 16 pounds on my 509 with SM seastrainer and reg. seawater pump !!! Which is plenty !!

I've had great results with the Merc water pressure relief valve.

Here's a thread on it.

I have used these and they work well

I can't post pic's here. Check this thread. Page 2. I made a pop off valve. 17 lbs at 36 - 3800, 20 lbs ate wide open 5000rpm.

Too much money for the merc plastic junk. My .02

is there any way to install a ballvalve to lower water pressure. i know trimming the pickup works better can also let u pickup more speed. was just wondering if it works i put some on my innercoolers but havent tested them yet.

I think all the above works,,,but the real thing and right set up is to cut the pickup down !!!!!

Why would u add a trublefactor in a boat if ther is a easy way to fix it and make it right for ever ?

thanks for the replies Will continue to file down, as speed increases so does water pressure.if that does not do it wiill make pop ff

A ball valve doesn't control pressure, it limits volume.

I installed the Merc relief valves on both of my completely stock motors after seeing over 35psi at cruise speeds. After screwing around for the better part of the summer trying different dumps, valves, different t-stat housings, I bite the bullet and installed the Merc valves. Now all is perfect!
