Jet Pumps / Re: cooling the motor with water

Sorry, but what I have highlighted is not just incorrect, but may well be the reason you have had problems with the Bassett and Rewarder "T" valves. Restricting the outlet side of the system can/will lead to overpressure conditions not just in the engine but in all the plumbing between pump and that outlet valve. Put the flow control valve before the engine and that likelyhood will be lessened , if not eliminated. If you have taken the time to read the instructions on Bassetts website regarding OT header plumbing, you will see that they use the valve on the outlet(aka "dump" line) to control the pressure which opens the "T" valve. The more you choke it down to increase temperature, the lower the RPM at which the pressure exceeds the "T" valve spring pressure, potentially opening it at idle which you do not want!
I get, and respect that, but the outlet valve, and the inlet for that matter, on mine was removed a long time ago. Both were run wide open anyway, never closed the slightest, so what was the point? Did it originally on some ill advice. Anyway, boat STILL, spilled water at idle.....Ask Skip....out the headers. This ultimately led to a head gasket issue due to reversion. 3 valves did this. Whether the JE is to blame and different, I don't know, but it is what it is. Driver controlled minivalve cured all that.
My intent was on log manifold boats, shoulda been more clear, I guess.
