Hi im new here , im french Canadian so my writing not always perfect.

I got a engine problem .

Engine 4.3 mercruiser 424106LRS.

My engine past 2100 rpm after 30 sec get in protection mode and alarm start with a continus beep sound.

We already did couple of thing on it.

Fuel: clean the tank and all hose , change the pump , change filter , put new gas

Power steering : change the pump and flush the system but still hard to turn.

Change : t-stat with right gasket , temp sensor ,

And the engine before this 30 second run perfectly to 4000 rpm

I just Don't know where to search ???

Thanks to help me

See if you can find the engine serial number. It will be a number, a letter, and followed by 6 numbers Exp: 1A123456 or 0W123456?

Is the motor fuel injected MPI or other?
