mercury 80 stalls

[john robbie]

hi, guys very new to boating,i recently bought a 14ft fletcher with a80hp mercury(early 80s i think)runs fine on muffs used it once on the river,when you put it into gear engine stalls and cuts out. you have to catch it just right to get going.once in the higher revs runs very well, can this problem be solved very easily? thanks john Robbie,Gloucester England.

Try turning your idle screws out 1/8th turn. How long has the motor sat up?

John if that don't do it try the Timing & Snyc of Merc Inlines posted by Clams on 3 May 06. This procedure works very well. Most will run fine on the muffs. The real test is when you put them under load. Also welcome to iboats. You'll find this forum very helpful there are some real experts on here that are willing to help.

Get a can of seafoam mix it a little heavy the first time to clean out the fuel system that should help it.<br /> If the plugs are not new replace them after that try adjusting your air screws 1/8 turn at a time<br /> (See clams link and sync for help adjusting them)<br /> also I would do a decarb so get a can of deep creep made by seafoam start with the decarb.<br />You may want to run a compression check. If that don't do the job you will have to pull and clean the carbs.<br />Good Luck,Tim

Not sure in England in the US just about all auto parts stores have it. I'm sure you can mail order from someone not sure who from you will just have to check. Case of have to I could UPS or fed X it to you Just email me if you can't find it. Tim
