Mariner 200HP water in fuel!

[diverdad]

Hi all, isn't technology great. As I write this post I am sat on my RIB at anchor. That sounds idyllic you are thinking! I'm sat at anchor as my engine has conked out!
I'm about 250 yards from the slip and in absolute no immediate danger, (other than from my very unimpressed teenage daughter). When the tide eventually comes back in I'll get a tow to the slip.

My question is; knowing how fickle the Mariner 200HP two strokes are, is there a recommend procedure for priming the engine, for the next time I start it. Or can I just clean out the fuel tank put fresh petrol in it and crack on?

Thanks in advance.

Just prime it.

If you can drain the fuel/water seperator off before you restart it it'd be a good idea though as all the crap in the bottom of your tank will have found it's way up the lines if there's any there.

Once you get it running, plan on an accelerated filter changes (say every 4 months, rather than a year) for the next few tankfuls. Don't forget the manufacturer's inline filter (usually under the cowl.) Water can break stuff loose that gas leaves in place.

Thanks for the advice so far chaps. I got a tow back to the Marina and got a jerry can of petrol. I flushed out the fuel line and tried it running from the jerry can but to no avail. I suspect the plugs are wet through. I'll recover the boat, (hopefully tomorrow night) and strip it down at home.

Just a quick update on the engine.
On Saturday changed the external filter/ water separator. I flushed through with fresh petrol... nothing, I then stripped out the plugs and gave them a good clean; it ran but clearly lumpy and some cylinders not firing. I then removed all the plugs and cleaned out the fuel rail by way of the bicycle type valve thinghy.
I turned the engine over to blow out the cylinders and empty the dirty fuel in the fuel rail.
I put it all back together and it is purring once again.
Many thanks for the advice from this forum and to Rob at Black Dog Marine.

try a fuel inhibitor in the tank for the winter

f your obm is an EFI , there is a filter in the vaper seperator thatt always seems to get forgotten, you have to unscrew/ remove the fuel connection on the top of the vaper seperater, (it was fitted on a lot/not all of 2/str efi obms)and there was useually a filter on the btm of the electric pump.
If you have carbureters remove strip examine clean and re-fit checking float hights etc.
good luck
