    Merc spark plug condition

    One question, I reset the fuel mixture on my Merc 25, 2-stroke a little on the richer side, due to the fact that it was set too lean. How oily should the plugs be? The plugs it's self on mine are coated in oil and the only dry spot is the electrode. Is that acceptable?

    Need help fast!.....Fixed?

    Thanks for the replies I got on my thread. I installed new fuel lines on the motor (connection at carb had minor leak), rechecked the water/fuel separator (oil residue around one of the plugs)...fixed it, then cleaned the vent on the gas tank and checked the rest of the lines for pin holes...

    Need help fast!

    '98 Merc 25 HP, 2-stroke Took the boat out today - ran great, started great, ran for about 2 hours and everything was fine. Shut motor off and started it back up - it was hard to start and would not run idle, but when the choke is pressed it will stay running. As you push the choke and put it...

    Reeds and Reed Questions

    I have two Merc 25hp, 2-strokes and one doner motor. The doner motor threw a rod and I got the whole thing for $50, and all the extra parts I will ever need. Now, one day I took the doner motor apart to find what caused it to die, and to hopefully prevent it from happening to my good motors...

    Neat idea for merc 25

    For years I have battled with the system of lifting the motor on a 25hp, 2-stroke Merc when I want to go into the shallows, and reaching over the side of the boat, behind the motor to release the catch is tough. So I got to thinking and came up with a idea that works, and works VERY...

    Advice Needed

    I am installing a fuel/water seperator for my 98' merc 25, 2-stroke and was wondering do I put my primer bulb on the gas tank side or the engine side? Also, it's a 10 micron filter and will that allow the oil to flow freely with the gas, or will it filter the oil out of the gas? Thoughts??

    05' Honda 20hp

    Taking a 05' Honda 20hp 4-stroke to the shop to have the prop shaft straightened. I was wondering if anyone know the approximate hours behind a job like this. I believe the tech said he was going to remove the shaft from the lower. Any help would be appreciated. Thanks

    Tune up

    Not a problem post, just some info. My 98' merc 25 always ran pretty good. A week ago I took it in for service and a tune up, and even though I thought it ran pretty well, it was a little sluggish....hard starting sometimes, and a little rough around the edges. Got it back and WOW! Touched...
