Do I need one for my jet botë? Where to purchase.
blower is finally getting installed

Berkley offers one as well.
What about the pressure relief setup? You did a LS swap mount kit and pump rebuild for a buddies boat, and put together a relief valve assembly that would divert excess water thru a dump port above a certian PSI. This was used with wet jacketed exhaust manifolds with elbows and tails exiting thru transomWater goes thru a jet like shit thru a goose with no "dwell time" and the true temp to monitor is the oil temp on jet boats , the water should free flow from the jet thru the engine with maybe a lever ball valve at the jet if desired ( the lever valve is also a good "fail safe" if a line ever comes off the engine )

I've always ran a -08 line into the engine and a -10 out of the engine. Hard to build pressure ever if the over board line is larger than the inlet line.
Just the tiniest grain of sand can upset a pressure regulator. And the 500hp+ water pump becomes useless.
I was amazed at the amount of sand a 454 gets in the water jackets in a season. All the river at Bullhead city and lake Mohave.
Grads idea is actually right for once. (Did I just say that?)

I’ll wait for @jetboatperformance to respond. They recommended, sold and built the pressure regulator setup that for my friends jet. At one time that was his preferred methodJust the tiniest grain of sand can upset a pressure regulator. And the 500hp+ water pump becomes useless.

That was the reasoning behind the pressure regulator. Interested to see what Tom saysI don’t have a t stat. I have the inlet and outlet coming into the oem water pump holes with no mechanical water pump.
When we pulled the intake on the old setup the intake gasket was starting to push water and coolant together. So I think the new drive probably upped the pressure
It's very simple/basic..plumb from the lowest entry point in the eng. Typically the water pump ports @ the timing cover area (unless you want to get fancy and go into the expansion plug holes @ the back/side of the block and out the thermostat housing ) up out the highest exit point (thermostat hsg) typically 1 exit line out to the headers/exhaust and the other out the transome or my personal preference out the side of the hull next to the drivers seat where i can feel it anytime i want to discerne if I need to back off the loud pedal or keep floggin it till it screams uncle. HahaDiagrams please or pics
And new problem. Carb stacks don’t clear. And linkage hits blower dual carb adapter View attachment 847324
Yeah gonna run spacers for that.
Who sells fiberglass dragster scoops with dual carb trays. I’m only finding single trays
it would be a real good idea. with the egt's of the blower, elevated rpms and eng. loads and all the oil will get pretty hot especially if you run very hard for longer durations. A sandwich adapter at the oil filter boss to a cooler is simple and cheap insurance. Your basic 2" x 12" cooler from eddie marine or other favorite parts supplier is sufficient. As has been mentioned already, monitoring your oil temps is as or more important (and more accurate) than water temps. Do you have a bilge area bulkhead forward of the eng/crank pully?No oil cooler
In line adapter such as a cast kuhl adapter?I've run the -08 to -10 dump also.
On the carbs cut linkage on bottom or short spacers. You can try to find a inline adapter as it might be cheaper if you don't have the fuel lines and sideways linkage yet
