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?

I did check the gate valve and the tee is open everything originally came out of a ranger jet with a Panther and worked great so transferred all lines as is into the Rogers hull with the Berkeley, motor is a 460

I am gonna throw this out there. I don't know anything about who or when your engine was rebuild or if this problem has been from new on or just started but food for thought I guess.

If one of the head gaskets was put on backwards it will cause the engine to overheat. In a vehicle you will notice some overheating right away but with how these motors are cooled you may not notice it until a heavier load is placed on the engine.

When the head gaskets are installed correctly a corner of the head gasket should be exposed at each head lower front corner.

Again just food for thought I guess.

You can see both tabs sticking out front of heads

The only other odd thing I have come across is a hose having a dam in it. Spent 2 days tracking down the problem only to find out that the hose didn't dam up until it was under greater flow. Just another idea.

I was thinking along these lines as well. May have a line coming apart or collapsing under pressure. Some of these older hoses could have an internal failure if they were ever kinked moving from one boat to another.

I'd replace the entire cooling system, lines, tee and all. It's so cheap $$ and should've been done when the new motor went in.

Could this bowl and impeller be causing my issues

Holy Hammered stuff Batman.

It's surely not helping things.

I assume you pulled the nut?

Get the impeller off and check the port in the suction housing and wear ring clearance.

You need a wear ring, impeller, bearing, seals and packing minimum.

You could likely clean that up and use it, what bowl is it? JG or JC? One piece or split?

I have a few one piece here. An impeller too.

It's a JB split bowl
