I have a 50hp mercury that has water coming out of the top plug and also has gas coming out of motor when it.

Question

doesn't start.

Answer 1

Sounds like you have a blown head gasket.

Answer 2

I also think the head gasket has gone what i recommend you do is-

* Go onto the internet and try and source the part yourself, this way you will save money. As the dealers will overcharge you.

*Then go and have it fitted by your local mercury dealer

*Then enjoy a working engine :)
