60hp Mercury 2 Stroke - power issues
OK, with other problems now under control... my next issue.. Engine Problems!
60hp Mercury 2 Stroke dated 1996 auto lube.
Basically I had to feather the throttle, while featuring the fast idle control just to keep the engine from stalling at any speed. When I finally got the balance the Rib took off and flew.... but as soon as I powered off for a larger wave etc I lost all power. It was hard at times to maintain 5 knots without stalling.
Engine looks like its been very well looked after but may be overdue a service.
Spark plugs look past their best so I've removed them ready to replace them.
I am wondering if the fuel pump is functioning correctly? Or maybe the ignition module controlling the spark faulty? Auto lube mix incorrect? Fuel filter if it hasn't been changed? (if the plugs were bad then perhaps this is too?) Possible engine breathing issues?
I have played with car engines for years and my experience says poor spark or fuel starvation, but I'm sure marine engines have a bit more going on being a 2 stroke.
Throttle cables seem ok. Throttle bodies seem clean and open freely with the loud stick... everything seems well greased and clean from dirt.
Engine sounds "normal". Actually quieter than I expected, smooth when going into gear, and when it did plane, very smooth power delivery.
I have to admit I am a little baffled. Any suggestions on where to start before I have to pay an expert?
