Mercury 2 stoke prob

[Pookay]

Now after reading Hightowers thread it sounds a reasonably similar prob.

2 weeks ago the fuel tanks were stripped and cleaned, new filter, carbs stripped and "meticulously" cleaned.

Before that engine would run but just be slow to get up to revs (hence why the clean).

Now runs ropey at low revs and keeps cutting out. Was advised by outboard speacialists to "thrappp" it as despite them "meticulously" cleaning the carbs they thought that there was a blocked main jet.

So today flat conditions - ideal for "thrapping" a 200 and off I set. Had to choke it up to even get it on the plane and duly "thrapped" got half way to Osborne Bay and with out warning it died. Started up and set off again ready for the "thrapping" of ts life and same thing dead.

This time,however, could not start. AT ALL. Checked fuel, checked oil, checked battery, waited incase I had flooded it - Nope, pumped and primed, Nope.

Flagged down nice people in another RIB (THANK YOU SO MUCH) who very very kindly towed me into Cowes :-(..

So now what have bill from outboard shop that needs paying and a boat that won't work...

The joys of boat ownership.

It is old and I know you can not polish a turd, but never the less I'd like to be able to use it.

Anyway now that's off my chest - any ideas as to problems, solutions etc etc??

Sounds like a carb fault to me. If your main jet is blocked it should'nt really effect the idle speed or Tick over. Sounds like the Carbs need to come back off and get looked at again. Are you sure they have been set up correctly. If its not picking up very well make sure the mixture srews are set correctly. Also check the pick up timing and the whole set up of the engine eg carbs are synchronized etc etc.

Take it back to outboard shop and tell them to fix the problem they have caused on your motor. Then tell them that you will be needing the boat next weekend and if it`s not fixed could they please provide you with an similar or better vessel, or if they prefer you could organise the hire of a bareboat charter yourself and say you`ll tell the charter company to bill them direct.

Note.

Running a 2 stroke with a blocked main jet is a good way to end up with a 2 stroke with a hole in a piston.

Many years of blowing up tuned 2 stroke motorcycles under my belt.

This is pretty much what I did.. But left feeling as though I owed them a favour and that they were being the "victim"...

They are busy (it's Cowes week) but this all started long before.. I guess it is not big enough money for them to worry about too much..

Thing being is that if (big IF) the engine is bollocksed then I will obviously be in the market for a new one - and will I buy it from them?????? I don't think so..

meant to be sorted today...

No I 'm not sure - is the short answer.

It definitely seems to be a fueling prob of some sort and more than likely,as you say, the carbs..

Just disappointed that before "clean" could reliably go anywhere just had to wait for the pickup. Now £400 later (not just for clean but other stuff too) dead engine...

Pookay! Any news on the Merc now that Cowes week is out of the way?
