Overheating issues

« **on:** July 06, 2016, 02:57:14 PM »

Boat runs great at any rpm upto 4 grand but once I start hammering on it past that the temp jumps way up gets super hot, inlet valve is all the way open and the outlet is about half I have slowed and opened and doesn't change the problem any advise would be appreciated

Sounds like the motor is full of crap/sand.

What is this outlet valve you speak of?

Motor has only been in the boat for a season with very little run time and I have a valve that comes to control how fast the water exits the motor

« **Reply #3 on:** July 06, 2016, 05:51:15 PM »

Try the outlet fully open and the intake 3/4 open

« **Reply #4 on:** July 06, 2016, 05:53:39 PM »

Ok I will try that I had a another motor in the boat and exact same thing was happening to it I was thinking maybe the impeller could be bad maybe

Check to make sure you dont have sand filling the block also

Throw that outlet valve in the trash.

What pump?

How is plumbed? Please include hose sizes.

It has a 1/2 pipe that comes off the jet to a valve then 5/8 hose to the basset t then that goes up to the plate and then I have 2 lines that comes off thermostat housing both 5/8 one line has a valve for the headers and the other goes to the valve out the back of the boat

It's actually just a hollow tee that goes to motor water plate

Bassett tee sounds incorrect.

Run water through it and take the hoses off at the front, start trouble shooting where you are having the water flow problem, if all the hoses that lead to the motor are flowing good, then it's in the block for sure, Pop out your freeze plugs and flush out the sand, hope you get it figured out man

First off id get rid of the old school valve at the pump you cant control the water coming in with that valve

« **Reply #19 on:** July 06, 2016, 08:03:16 PM »

Why are there so many valves? Leave the gate valve, it's fine, pull the piping apart at the pump and check it for rust /debris.

Lose the valve on the dump, I still think you have something funky with the header valve, hard to tell from the pictures.

« **Reply #20 on:** July 06, 2016, 11:27:23 PM »

Just to be sure, when it's running, was there water coming out of the dump line and headers? What was the stream like out of the dump line?
Did the stream change when you opened the dump valve?

Are these the same water lines and fittings you had on your old motor?

I ran water straight thru motor and it seems everything flows fine

In the picture that shows a yellow handled valve and a tee. Is that the tee to the headers or the inlet plates on the motor?

That goes to the headers

ok. Is it possible that your gate valve by the pump is not opening all the way? Have you looked at that tee for the motor to see if it is an open tee. I am only asking because you said the last motor did the same thing. Especially if you reused the same components over on this motor. That would lead me to believe that one of the components is faulty. What motor are you running?
