who has the best water regulator at a reasnable cost to maintain realistic water pressure w/ B/B chevy and ot headers, Thanks Rob...
Not certain about the best, but this is what I purchased at the advise of one of the most respected in the jetboat business. I believe I purchased the 3/4 inch version. Works great, no issues.

:idea:
"We do not recommend using these regulators for applications less than 20psi. If you need your pressure lower than 20psi then we would recommend contacting a regulator manufacturer for your specific requirements."
wonder why?
Use a water bypass valve, NOT a pressure regulator. There is a difference. Much simpler to plumb and much more reliable. (I know, I know, regulators have been used with good results on some boats). Bypass valves do the job BETTER! And the bypass outlet needs to be at least 3/4". The ones that some others sell are only 1/2", or 3/8", and that's not big enough for a lot of boat applications.
Does anyone want to express their opinions (the good the bad and the ugly) about these regulators?

If you plumb your engine properly you may not have a pressure problem, in most cases. I have not had a problem with the set up I use but that does not mean it is perfect in every case. But I believe that it works fine on the average jet boat. The best way to get your answer is to put a pressure gauge on your engine and see what you've got and go from there. The valves I use dump most of the pressure but not all of the pressure. I try to shoot for around 15-25 lbs block pressure. Jim

Regulator (http://www.grainger.com/Grainger/pro...840040&ccitem=)
I have used this regulator for 4 years now. Never had an over heating problem, or a problem with too much PSI. At WOT my block is at 28 PSI. When running, my motor needs to stay cooler then most and in the hot desert summer sun, my motor runs a 125 degrees. WOT for 10-15 seconds it jumps to 140 at the end of the run, and soon after comes back to 125. You don't want to use a regulator to control temps though... you want to use a valve on the exit line to do that.
Good luck with what you choose... just stating this has worked for me and everyone I know who has used it.

I've had it on my jet for 3 years now and never had a problem with it. I changed over to the banderlog valve before last season and it's even better now. My boat runs 150 all the time. I set it up one time and haven't had to mess with it since that time. No water in the oil, no worries.

HBjet- I think you'll get better results with that bilge pump if you hook up a hose and dump the water out of the boat...

Well I guess I'm good to go...one line and 2 dumps out keeps my psi right around 11-15. And the Rex t-stat 160-170 water temp.
also thenks Duane for your feedback.
