hot pisser water

[Pablo]

Anyone have ideas why my ski would be running scalding hot? I've got a single cooling line coming from pump that splits to a T for the mani then out of one side of cylinder head to bottom of head pipe then out of b-pipe to a T for FCV and other side to pisser. The other side of head goes directly out to pisser. NO RESTRICTORS ARE IN LINE. Both pissers are flowing freely. The water coming out of the pissers is hot!! I didn't check the temp of it, but when it hits my legs it scalds them. I'm gonna run a second cooling line off my pump to the manifold and see if dual input helps cool it down some.

In addition to that the engine side of the coupler is hot as hell too. I don't know if that's transferred heat from the cases or what. I just had CP Watercraft do a engine build for me (true& weld, bore, port, epoxy) and it starts and runs fine. Does a built up engine run any hotter than stock?

Dual cooling lines!

I meant to call when I got back but I touched my coupler when I got done and it was very hot as well. Not sure if it's normal but I lined up my coupler and greased it before installing it.

you could have a stone in the water line slowing the flow.

Is the T between the bulkhead and the manifold causing a restriction in your cooling? There is a good amount of head loss in T fittings and at least a larger Y fitting would be better.

A built engine will run hotter than a stock. I'd recommend on the dual cooling though since your partially there already. Also you should ask the builder of the motor what they think since they're the ones that built it.
