Hello.

Remove the exhaust riser and check the water passages are they blocked?

Customer: replied 1 year ago.
No. Look perfect

Going to spray water through to verify. I checked this earlier this summer and they look the same. Problem has been there all this year

Does the engine over heat at any particular rpm? Could I get the complete model number4.3GL???

I can get a gasket until next week. Great.

Does the engine over heat at any particular rpm?

Could I get the complete engine and drive model numbers please?


Depending on when the engine over heats can lead us to the possible problem.
If you had told me you had inspected the risers before I would have gone another route. But I still need the info to give a possible cause.
