1979 merc 115...specific

[mellowyellow]

afraid my last post was rather vague...<br />I have purchased a service manual for<br />the basic maint., but was wondering <br />what problems can be caused from a<br />motor not being used for an extended<br />period of time...what extra steps might<br />not be in the basic maint. manual????<br />prefer not to even attempt to run her<br />if it's gonna cause damage which could <br />be prevented.

Specific, Mellow?<br /><br />What is an extended period, 6 months, ten years?<br /><br />You probably should replace the impeller, pull the plugs, squirt some WD-40 into the cylinders and carefully pull it through by hand a few times.<br /><br />Dismantle and clean the carbs and fuel pump.<br /><br />Do a compression check and, while you have the plugs out, check for strong, blue spark on all cylinders.<br /><br />Feed her some fresh, 87 octane, 50:1 mix and fire her up on the muffs. Kill each spark plug, one at a time and confirm that each one causes a rpm drop.<br /><br />If she passes all of the above, you are ready for the water. After you have used up the 50:1 mix, if you have oil injection, too, check that it has used oil from the oil tank and use straight 87 octane thereafter.<br /><br />Good luck.

hasn't run since 97... very limited before that.<br />you could eat off this engine, but am afraid of<br />consequences of non-use.<br /> [*]
