This was on my boat when I bought it. Its designed to be used with a standard water pump. I tossed the water pump so this is just the water neck piece with hoses that are pictured.

Anybody looking to control the engine temp the right way needs to snap this stuff up. It will run 155*F all day long at idle or WOT.
This is the ONLY thermostat kit style you should use on a jet.... ;)

How does this work exactly gt. I'm interested in it for that price. I have a water pump as well

What it does is uses the water pump to circulate the water in the engine block until the thermostat comes up to temp, then the thermostat will start to open to control the outlet temperature of the block, all the while pushing the unused and hot water out of the two outlets.
This is the way in I/O system works.
You will still need the much debated gate valve to throttle down the flow and reduce the pressure, but this makes the engine temperature sill consistent at all engine speeds.
The hose, if in decent shape, is worth the asking price IMHO.

msisco, any chance you have a picture of the underside?

Hey GT, I was reading your posts in the thread about water pressure...you were pretty adamant on NOT using a tstat...in THIS post, what makes THIS system any different than what that jet fever guy was trying to argue?? Just tryin to learn something.. :)

Bike racks, after school..... :sly:
The thermostat kits you can buy on the aftermarket are only a spring to Pop-off when pressure gets to a certain point and a thermostat that closes off water flow from the engine. With a setup like this, the water pump circulates the water within the engine making the water temperature pretty darn consistent throughout the entire system. Whereas the regular kits make the water "stop" in the motor allowing the engine to heat soak all over the block and heads. I have seen the motor temps have a 40*F+ difference running the "marine" kits. the rear cylinders always run really hot and when they puke, it will be the rear two cylinders that have an issue...
And FWIW, if the engine is machined correctly for a "Jet" application, thermostatic control is simply not necessary. If you want to build a motor with much tighter tolerances, a stat is almost a necessity. You do have to keep any eye, or simply control the oil temperature however.
Hope that answers your questions... Punk. 8)

Dude I love your references! Bike racks..lol well I think I see the differences now between jet fevers system and this one.. jet used a "set it and forget it" type of pressure regulated set at 12psi and anything over 12 is overboarded. This one sounds like the pop up valve is acting like an street engine radiator cap to relieve too much pressure..yes?

Why am I a punk?? Lol I bet you wear those "old guys rule!" T-shirts..huh? Like my dad..haha! Just poking fun atcha bud ;)

Also, do many of the jet veterans run an oil temp sender to a gauge on the dash?

No, not really, the spring in the thermostat housing is to hold the plunger into the divider of the four hole housing and relieve when the pressure changes from idle to anything above idle. Basically keeping all the water going through the outlets of the stat housing under all conditions. Also acts as a check valve upon shut down.
It has nothing to do with block pressure and even with the thermostat kit, you need to regulate flow somehow, a gate valve works fine.

IMHO, oil temperature is more important than water... So maybe the answer is "yes"? Not sure, I am not a veteran... ???

Oh no GT im so NOT trying to get you all bent outa shape, in fact I highly respect your "humble opinions" lol now I totally understand this concept..and I figured you to be a veteran in the jet boat world because of your experience and knowledge :)
