    Hi. I'm replacing my ignition switch with the MP39760 model. This doesn't seem to have an option to fit a kill switch lanyard.( I'll check with the supplier) I want to fit a switch on the dash. Can you tell me how to wire it up to the engine?

    Hello All. Still no joy starting my Johnson 50. Compression good, spark good, woodruff key in place, carburetors have been cleaned, linkages checked. The engine is not firing, even when spraying 'Easy Start' directly into the carbs. Is it worth me inspecting the reed valves (I've only recently...

    Dual battery wiring query

    Hello, I have been tinkering with my dual battery wiring on a cruising sailing boat, fitted with a Volvo Penta 2002 diesel engine. Things seem O.K., except for my Makita diesel heater, which won't turn on. One dual core wire leading to the battery has me confused. Sheathed in black, there is a...

    Hello all. I've got a stuck Blakes sea **** 1 1/2". If I can't unstick it, I will need a replacement , but I can't afford traditional bronze fittings. Can any cheap alternative do the job. Osculati seacock with check valve is very cheap, but I'm not sure it could do the job.

    I've had a real problem starting the engine for a long time. Would crank but not fire up.

    Installing power trim/tilt unit onto 1996 Johnson 50hp outboard

    My tilt/assist unit broke. I finally found a power trim/tilt unit from a 1989 model which I believe will fit. I have the hydraulic unit (397532, I think), and the motor (432226 ). That's got a green and blue wire connected, and a black wire is attached. What other electrical bits do I need to...

    johnson 50hp 2-cyl, 2-stroke, 1996. Motor cable assembly connections

    Hello. My electrics at the engine area are in a real mess.

My problem then comes with what to attach to the other ends. In particular...

    Hello. I just bought a used Yamaha 2hp 2-stroke engine. Took it out and it idles fine, but dies when I try and increase speed. Starts up again after a few minutes, then the same thing.

    Hi, what's the difference between the upper and lower carburettors on the above engine? Is there a way of identifying which one is which when they're taken off the engine?

    Hello again. Engine started and ran, but won't switch off using killswitch or by turning ignition key to off. This is despite installing a new wiring harness recently.

    My engine, above, has not started properly in its recent history. I thought cylinders were flooding. Refurbished the carburettors, replaced a damaged fuel line (from the VRO fuel pump to the primer solenoid). Today, on a hose and muffs, it started, no choke, open throttle. But it very soon...
