Hi,

Can anyone point me to a link for a free download of a manual for the above engine please.

Also I assume a normal smallish in line fuel filter for this engine should be ok or should I try to source a genuine mercury part at probably a ridiculous price?

The engine is probably 20 year old but has been running very well. Currently starting first time but cutting out after a short time. I suspect its a fuel issue.

Thanks in anticipation of usual excellent advice.
 
If it is anything like the 3.5 engines, your engine will probably have a filter in the tank. Remove the fuel tap and the filter comes out with it. But there's nothing wrong with fitting one of the cheap in-line filters as well if you want.
 
The owners manual should be available for download from the Brunswick Marine site download center

Click the link to the Download center at the bottom of this page http://www.brunswick-marine.com/ It does not seem to be working at the moment but normally does. Working OK later

Sometimes its difficult to locate the correct manual but ploughing through what is there without entering a year will pay off.


Some workshop manuals on http://boatinfo.no/lib/library.html but not checked for yours. Look under Mariner as well as Mercury


Check the fuel flow to the carb and also the tank vent. If remote tank, will pumping the bulb keep it going? If so look for air leaks into the fuel line or defective fuel pump.

There will be fuel filter somewhere.... check it

Exploded parts diagrams on http://www.boats.net/ if it was a model sold in N.America.

If it has an internal tank the filter is sometimes very small (because it's underneath the tank) and difficult to find a cheap alternative. I have fitted one in a different position to save spending £25 on a genuine filter.
