My 2011 4 stroke
5 hp Mercury
pushes my boat. I've started motor
sailing a lot as of late last year. The boat is a 1974 6600 lb Bristol. The engine is high or very low on a bracket. I've run the crap out of it.
I finally did some maintenance
this year: engine oil
, lower unit oil
, impeller, bought fuel filter
but did not replace, didn't replace the plug
but have a spare as well.
This engine hasn't missed a beat, but I am old enough to remember chokes on old farm trucks and lawn mowers, etc so I know how to start it.
My last resort is rebuilding the carb if there is a problem. The couple times the engine didn't seem to want to start I hooked up the external tank and blasted in some fuel with the squeeze bulb. Engine started right up.
I normally just use the internal tank for leaving the slip, but if i'm motoring back across the bay during the wind
lulls around 10am I'll hook up the external tank for the 3 hour tour (all usually on autopilot)
I'm thinking some of you guys just like taking things apart.
These 4 strokes engines are much better than the 2 strokes and they don't foul the plug(s) either like the old 2 strokes used to do.
Btw, I only started adding the STA-BIL because everyone said I would have a problem with the ethanol fuel. I never did but why take the chance.
