Although I haven't had fire, my Suzuki gave its first splutter for the first time ever yesterday - upto 5000revs, and then down to 3700revs, then back up again, then down to 3700revs again. The engine was fine upto 3500revs, but above that, it felt like it was missing a cylinder - it must have known that it's going in for 200hr service tomorrow. Similar to you though, my warranty is now out, so if it's something more sinister, things could get expensive

I'm having similar issues at the moment, but I know what my problem is - cr*p in the fuel.. blocking the fuel filter and not allowing the clean fuel to get passed... I empty the filters, and its all ok again for a bit....

Free trader Sounds like you got some shagged injectors,... or one is enough,. to shut it down to guardian mode. Optis are well fussy bout fuel but great none the less

How did you winterize the opti? you didnt put some distillate stuff in the tank by any chance ??

Boat was winterised by previous owner, so don't know if there's any distillate in tank.

Engine had 430 hours, and according to diagnostics had been well maintained and not over-revved. I just can't believe an Opti would blow out in these conditions.

Engineer's looking at it today or tomorrow, so will post results then.

Cheers


Phil

Yea I had a dealer put some quicksilver fuel additive in my tank for winterisation, but its not meant for fuel injection engines, only carbed ones. I'll get the name of it to be sure, but it ko'd one of my injectors, it bunged it up solid, and mine hadn't done that many hours either. Warranty took care of it but it was the hassle factor. I drained my tank, flushed and re filled, no problems ever since. Even if its not whats stopping yours now, Its worth noting for reference. I don't put anying in the tank, just leave it.

Good news

Local Merc guy has taken a look, and reckons it's the fuel rack that's gone. So we're talking a few hundred not a few thousand. I could have kissed the guy.

Hopefully the work should be done this week - just in time for the bank holiday. Big thanks to everyone for concern and advice.

Been holding off asking how the boat is since you posted the bad news.

That's great news.

Glad you found, another, nice Scorpion.

Regards

Mark

I am soon to be dusting off the cobwebs on my similar unit.
Couple of silly questions:
1) I left some fuel in the tank (actually more than I thought) but it has sat since late September. Should I dispose of this?
2) Should I and how do I clean the tank (underfloor jobbie)?
Engine was services and winterised, new fuel filter added.
Would be grateful for some advice...

Many thanks.
