    E8RCRM 8 hp Timing Marks?

    4-pin harness connector dirty, pins shorting. A mess inside. Cleaned, realigned pins, confirmed continuity. Timing back on track. Signals look clean. J

    Ring Set Tops vs. Bottoms

    Got a ring set for a 50 Merc, 3 cylinder. 2 rings per piston. 3 rings are black rimmed, 3 are silver rimmed. They mic the same, both are tapered. Which are top and which are bottom? Thanks, J

    No spark on 2 of 4 cylinders

    I'm also chasing one of these on a 1980 with type V ignition. On mine, bottom 2 are out. I swapped trigger wires to switchbox and problem followed. I have a thread out now asking if that means trigger assembly is out. Appears that if switchbox gets a signal it can process it on through to the...

    1980 50 hp 4 Cylinder, Bottom Two Dead

    Took a look at a 1980 50 hp, 4 cylinder, 2-stroke, serial 5634000. Type V ignition. Verified bottom 2 cylinders are dead. Under the flywheel there look to be 2 triggers in one molded housing ring about 90 degrees from on another. Sits inside, beneath the stator coils. There are four wires...

    1970 18HP Evinrude: At WOT, RPMs vary greatly

    Likely a spark issue. Might be fuel but verify ignition before you move on to fuel delivery or you will spin in and crash. Verify ignition with a timing light on each spark plug wire. Remark your flywheel for good reads of both TDCs. You'll see if good, bad or ugly. With engine capable of...

    Engine won't stay running

    66 views with 2 responses. Woefully inadequate. What engine are we talking about? What's your serial number? Disconnect the kill switch circuit to leave it out of diagnostics. It's confusing you. Leave it out for now. If by some miracle the engine starts and runs you can kill it by choking...

    Small Flywheel Tool

    Got a flywheel tool from OEM. Nice, works great but is too large for the small engines, 8 hp. What are you using to hold the flywheels on the smaller engines? Thanks, J

    Why is fuel leaking from my vapor separator?

    Hmmm, .... Schrader valve on fuel rail, ... presence of fuel. Must be a bleeder. Thanks, J

    Only starts with one plug removed

    30 views, no responses? Serial number? What's your history with the engine? Did it ever run for you or are you troubleshooting new-to-you problems? Cover the basics even though they may not seem relevant. Compression test. Post the numbers. You may have a crankcase ventilation problem if a...

    Am I screwed? 86 60hp Mercury Flywheel Removal/Timing

    Timing light. All cylinders. What's the data say? J

    Flywheel removal question, please.

    Yikes! "hold pencil to top cylinder (#1) and rotate flywheel until TDC. Then replace flywheel." Finding TDC with a pencil has nothing to do with replacing a flywheel. Information's missing in a big way here. So we're saying the engine sounds like it's "off", like it's misfiring? What's your...

    Just bought a my first boat. Need some help!

    There's a lot to go over if this boat is new to you. You should check out all subsystems. Do not rely on someone else's experience. For instance, I don't see a definitive comment, is the VRO bypassed for certain or are we just talking? If the VRO is working then do not premix your fuel...

    68 Johnson 9.5

    Why are we on this path without checking the basics? Are you running on one cylinder? Pull each spark plug wire one at a time and see if performance changes. If it doesn't, then the cylinder isn't contributing. Are you misfiring, firing both cylinders but one out of phase? Put a timing...

    1976 Evinrude 6hp..only getting spark in one cylinder.

    "and once we got it running the top coil was not sparking once again" Coil not putting out or spark plug not firing? NGK plugs? Seen several failures this year with great coil energy and nothing firing in the cylinder? J

    Just about to go crazy trying to get this motor running

    Would it make sense to put a timing light on it? I'm wondering if something is out of time. When you choke it or let off the key and the cap fires, does the engine backfire? J

    E8RCRM 8 hp Timing Marks?

    Thank you. racerone, the points are on the shelf along with the Mercury head gaskets... Flywheel key is good. Doo-dads under the flywheel look good but I haven't tested anything yet. Looks simple enough with one charge coil, one trigger, two magnets in the flywheel. I think I know where I'm...
