    1985 110Hp Mercury outboard

    Or not enough and some corrosion from sitting up if that's its history. The spring loaded fingers that grab the flywheel have to spring out as soon as you start pulling the cord. If dry and corroded, they can't easily swing out just like too much old grease can dry out and be in the way for...

    1998 bay quest with 150 johnson ocean runner

    I grew up on OMC and my last one was a new 1972 125 HP V4. Had if for 7 year and sold it to a friend. Did nothing to it the whole time....didn't know back then you were supposed to do this and that but apparently it didn't matter that I didn't. Never had a quiver of a fault the whole time...

    1991 mercury 60hp clutch problems?

    The tell tale water being cold is normal when the engine isn't running. Engine isn't producing exhaust which heats the tell tale water. If you are on the hose and the engine is just idling, the water may be colder than the minimum exhaust flow/vs water flow can heat it up. 140F, even 125 can...

    1991 mercury 60hp clutch problems?

    The pellet part of the stat operates it. Therefore the pellet needs to be in the medium you wish to monitor...inside the water chamber.

    1991 mercury 60hp clutch problems?

    That's the "overrun clutch" functioning. The rear of F gear is configured in a saw tooth configuration where R is vertical sided slots and cogs. Any time the engine is in F gear and is going slower than the prop is turning....you are on plane and slow down to do something is when this is...

    ‘91 merc 60hp overheating alarm buzzing

    If I were to do an inspection where I may have something clogging the circulation of the cooling water, I'd do the following: 1. Inspect and then replace impeller. While water pump is open, put muffs on the LU and squirt water into the pickups on the LU and see if it freely flows into the...

    time to replace power trim relays on merc 90hp 2001 again?

    Since the relays are sealed but the contact to the external wiring harness isn't, my guess is that in your replacement operation, you slid the relay contacts out of the sockets and slid the new ones in, both operations cleaning off the wiring harness contacts surfaces. If you have the problem...

    2000 90ELPTO: Which sleeve: L130OB or L167OB? (short or long exhaust port notch)

    How do you know it's working...define working....I never changed them just to be changing them but if I felt like I needed a new one the engines got a new one....course I don't go a couple dozen miles out in the ocean either. Never had one in bad shape. Some folks report that they have chunks...

    Your Best Technique for Rope Starting Merc 20hp EFI

    No! I've had small, single cylinder 4 stroke engine prefer a mid range RPM to a WOT throttle position with the same cranking rope pull. The engine has a steel wheel with blades attached.....starting under load essentially on my leave vacuum. I'm guessing the fuel availability is the problem...

    Prop is making thumping / clicking noises when hand rotated (video)

    Powerhead: That device that causes the drive shaft in the outdrive, mid to lower unit in an outboard, to turn.

    ‘91 merc 60hp overheating alarm buzzing

    My service manual for 100 hp range 2 stroke Mercury's says to expect problems if compression is less than 120 PSI. You're close and it may be ok but the manual says what it says!

    Inspecting 2002 Tracker 125 HP Outboard

    I just bought a used iMac desktop and it has the latest software (Sequoia 15.7.2). As you say, the automatic correct function drives me nuts....it thinks it knows what I am going to type and it corrects the spelling of some words to its liking, not my deliberate spelling. I went to the section...

    Your Best Technique for Rope Starting Merc 20hp EFI

    Most sparked outboard engines use a rotating magnet on the flywheel passing an iron core coil of wire, anchored adjacent to the flywheel magnet to generate the trigger voltage to cause the spark plugs to fire. The equation for how that works is V (output voltage amplitude) = [ L (inductance of...
