Hi,

My water pump belt came off this weekend. I was cruising at 4300 rpm when I speed started dropping. Turned off engine immediately (temp guage was pegged to the red hot) and lifted the hatch. There was coolant spraying all over the place and lots of white smoke (steam?). There was no noises just a loss of power.

Anyway, my heart stopped and now my checkbook is scared.

It is an 86 merc cruiser 260.

Question, when I lost RPM's, was that due to loss of compression in the engine (head gasket maybe)? I let it cool down and turned it over a few times to move the cylendars a bit and prevent them from seizing.

Assuming the worst, I have read that it can be a better idea to just purchase a new motor...any thoughts?

It's sitting in line at the mechanic's but its killing me not to know what to expect...any thoughts?

I must mention this "I am a complete moron for not keeping an eye on that temp guage".
