Mariner 40 help!

[lizardland]

Hi Folks,

my Mariner 40 has died...

I was flushing it on muffs this afternoon after being in the sea, everything running well, pumping water fine. The motor spluttered and died, it started on the next pull, ran for a second, spluttered and died again. Same thing happened after another couple of pulls, now it won't start at all.

It's an early 90's Mariner 40 pull start. The previous owner said it was occasionally hard to get going but usually taking the plugs out and giving them a clean was all it needed and that's worked so far. But this time it makes no difference. I've tried for a good 40min to get it going this time, nothing. I don't know if it's relevant, the motor ended up underwater for a few seconds yesterday (boat got swamped by a container ship wake just as I was trying to get it on the trailer at New Brighton beach, ended up bow up/arse down in the sea half on the trailer).

I know it's not easy trying to diagnose over the internet but could anyone give me a steer on things I should be looking at?

Cheers,

Stuart

Possible water in the electronics so I sould disconnect all the various connections and check they are not damp.

Check for spark at Plugs
Check Fuel supply

I took out the plugs, pulled it for a while, cleaned the plugs, refitted them... and it started! Ran for a bit then died again.

Water in the fuel maybe?

Sounds like it may be and if so you could do with getting that sorted ASAP as it you have sea water in the cylinders it wont take long for permanent damage to occur if it hasn't already.
