    Mercury 1987 9.9hp power loss

    The motor started up just fine at the boat ramp, I put it into gear without any issues, and away I go down the lake. I have been cruising for about 10mins when I hear a slight difference in the motor noise, enough to make me think something was not right. All of a sudden, i have zero power and...

    Battery Charging

    Is it possible to charge my battery while my electronics (fish finder, nav lights, aerator pump.) are connected or could it "burn up" the electronics? The battery is in a tight spot and it would be nice to leave everything connected. I have been disconnecting everything while it charges... David

    15-20 pulls to start Mercury 9.9hp

    A while back I had some issues with my engine running rough and sluggish. I ended up changing out the fuel pumping mechanism, fuel line, fuel filter, fresh gas/oil mix and spark plugs.

    Carburetor Fuel Additive

    Would it wise to use a Carburetor and Fuel Injector fuel additive for my 1986-87 9.9hp Mercury motor? Unfortunatley, I cannot find just a carburetor cleaner additive. It is only sold as a carburetor and fuel injector. Could it cause future issues like "gunking" up the fuel? Thanks, David

Does any one have a suggestion on what to look for and what to repair before the spring comes around. THanks for...

    15 pulls to start motor

    Does anyone know why it would take me 15+ pulls to get my motor to crank? It is a mercury 9.9 1986 or '87 and runs great once it starts. It only happens once, which is the first time I crank, after I have been riding around for a while, I can sit for over an hour and it will crank on the first...

    Gas leak Mercury 9.9hp

    I have a 1987(i think) Mercury 9.9hp 2stroke that seems to be leaking gas. The other day I had a hard time starting the engine until it finally cranked, but it just did not seem to have the pep it had a couple of weeks ago when I was out. I was out all day fishing, and it cranked everytime on...
