    Spark plug wires

    Hi all, I'm putting together an order for iboats, because parts seem so much cheaper over there in the US. I'm not sure which are the correct HT leads (spark plug wires) for my motor - its a 1991 Force 70hp with the Mercury Thunderbolt ignition. Can anyone point me in the right direction on...

    Ignition Coils

    I'm getting a poor spark on the number one cylinder of my 1991 70hp Force. Looking at the High Tension lead, the metal connector inside is corroded. Is it possible to change just the lead (or replace the cap/connector) or do I have to fork out for a new coil? It appears as though the lead is...

    Another rectifier / charging question

    I've just recently replaced the stator and rectifier on my 1991 70hp Force for new Rapair/CDI parts. I was tinkering today with the motor in a very large bucket, and decided to check the voltage at the battery. With the engine off, the battery was showing around 13.5v, after starting at idle...

I particularly like the Teleflex Amega range, as they'd match...

    Force 70 Flywheel Removal

    Hi all, I've had a quick search through the forum but couldn't find an answer... I'm trying to remove the flywheel from my 1991 Force 70 motor to replace the stator - I've removed the nut with an air impact wrench and I have a harmonic puller to hand, but I don't know what size bolts i need...
