Hi I'm wade. I'm having problems with getting hot. 87 carrera eagle ,454 ,12jg , logs and snails. Just put in new impeller and wear ring. Noticed its steaming from exhaust and logs are real hot to touch.

No thermostat , don't know how hot. Temp sender will be here in the morning. 1 valve in supply hose. All the way open.hotter than it usually gets.  Noticing lots of steam ,snails are to hot to touch. Just rebuilt pump and replaced imp and wear ring.

Steam is normal.  Snails are always smokin' hot from the git go.  Logs should not be hot, just barely warm if engine is running.  Is this a noticeable change, or are you just now noticing these aspects of a new to you boat?

hi, i read either somewhere on here or on another jet boat forum about someone having a similar issue.  i dont remember if he  specified if he had recently rebuilt pump....however...he did have an overheating issue.  turns out he had a small pebble/rock stuck in one of his valves.  he found it after troubleshooting...process of elimination...  said pebble restricted water flow enough to cause it to run hot.  could be worth a look...

or.....maybe now that your pump is fresh and tight, motor works a little harder, runs a tad hotter, and its become noticeable to you.... that be my guess (not sure if this would apply)...especially if youre running just as hard as before pump rebuild.

yeah, from what i hear...hole shot is imporved....top speed is fairly consistent....with a few lower revs, depending on how much it was slipping before.
i havent read about sand getting into logs/snails....but i wont say it isnt possible! 

I just pulled both drain cocks and got out a little sand but not a whole lot.

Well I hooked up a mechanical temp gauge and went and drove boat really hard and only got it up to 190. I guess I'm happy for now.

Ok since my gauge had never worked what temp should my engine be running.

When I get home I'll try getting more sand outta the water jacket. Guess I'll try the zip tie in the drain holes on each side of the block. Any more suggestions?

Maybe u did this already but unhook the inlet to the block hook up your hose and make sure that it is not restricted first.
Also how does the oil look?  I mean the water is coming out the exhaust right and not restricted on the exit?

Could there be a restriction from the pump to the block inlet
