Default Re: V8 overheating problem ( 5.7 mercruiser)

Thanks guys

I consulted a couple of marine mechanics and they told me it could be the head gaskets.

The motor is 9 years old so I assume the risers and manifolds are shot, again my worst fear is the induced heat on the motor causing internal damage like on the heads etc. etc.

I really don't know how hot it got but I saw the temp. Gauge maxed out.

Funny thing was, even overheating this frigging motor revved up quite well, the motor responded to the throttle when trailing on the boat.

Thanks
