    Mercury XR2 150 stuggling to get on plane.

    Check all wiring and especially grounds. Check plug wires and plug fits to spark plugs. Check stator output. Check rectifier and diodes. Battery and connections all ok?

    Recommendations for outboard powerhead machining work

    Make sure it’s a red seal machinist doing the work. Don’ t exceed 10% bored out. Don’t polish too smooth so it’ll hold oil. Use best rings and pistons you can afford. Do all three cylinders.

    Nasty time consuming problem. Check for melted or burnt wiring. Check back of components for signs of overheating. Clean paint from ground connections. Check diodes in voltage regulator. Check voltage output to the electrical system…is it steady or variable? Make sure you have a decent...

    Merc 6 Four Stroke Tiller

    Looking for thoughts. My Merc 6 hp, four stroke, 2017, has a problem at full throttle on the tiller. When turned to full throttle, the RPM, at the top end varies up and down, so it isn’t always at full throttle. Carb has never been boiled out and am wondering if the problem may be...

    Mercury 6hp 4 stroke hard to start

    I have the same motor. A dealer told me to take apart and boil out the carb. May try it this winter. I think it’s a carb problem, but I’m going to go at the issue by checking ignition, compression etc.

    Hard Starting Merc 6

    The engine is 4 years old and is very hard to start. Choking sometimes helps and other times doesn’t. A dozen pulls on the cord won’t always start it. Getting it going is a hit and miss exercise. Good gas, clean plug gas cap vent open. Going past the restart position on the tiller handle doesn’t...

    2018 Merc 4 stroke 6 hp - hard starter

    This motor is stored on the transom of the boat with the shaft vertical or on the transom in the shallow drive position. How would any oil in the crankcase get into the carb? Almost defies common design sense….

    2018 Merc 4 stroke 6 hp - hard starter

    This sweet little motor has turned nasty. Will take easily 8 pulls of the cord to get it going, choked or not. New plug made no difference. Suspect a carb set up problem. Need a carb schematic and adjusting sequence etc. Clean gas filter and fresh gas used 87 octane. Ideas appreciated!

    Setting Timing at WOT ????

    My 25 HP 1987 manual start has me stumped in I don't know how to set the timing at WOT with no test tank or test prop. Don't like the idea of tying at a dock and doing it and it sure won't be done with me hanging over the transom. Is there any way to set timing at some point before WOT ? I have...

    Idle Relief

    What is the purpose of the idle relief holes on a Mercury 25 HP (1987) ? Is water ever supposed to come out of the holes when the engine is running and water is also coming out of the "pee" tube ? The faster the motor runs, the more water comes out. I just pulled the lower unit and put it back...
