Engine takes longer spark plugs and the local engineer installed short reach plugs which to me means the heat was concentrated in the spark plug hole causing the spark plug casing to overheat and...

    Mercruiser 3.0 LX spark plug failure

    3.0LX - Mercarb to Rochester ?

    Thanks Scott. What has to be done for it to fit ? The seller said they’d supply it with the correct fuel inlet so the pipe doesn’t need to be bent.

    Urgent help - nearly broke down at sea. Fuel Problem.

    Had at least 3 tanks worth of fuel since coming out of storage. New filter too. Wouldn’t that mitigate the goo ?

    Urgent help - nearly broke down at sea. Fuel Problem.

    Thanks and I agree about the bearing as the engine temp doesn’t move from 150 and the engine spins up nice on the starter. This engine doesn’t have thunderbolt it’s EST ignition module and the module was replaced last year.
