    Re: 1965 9.5 HP Johnson MQ-11C - Rough Idle Help

    Hi.
    This has been a long posting. Can you refresh our memories? What are your motor's symptoms?
  3. Re: STOP CALLING THE 70's Vintage, antique etc!!!

    Thanks, Mr. Scott. I've been struggling with some vintage problems, but not ready to give up yet. Ha! Still love your old post on those vintage pressure tanks, think it's in the archives already....
  4. Re: STOP CALLING THE 70's Vintage, antique etc!!!

    Ha! I cracked a couple Hamm's and read Ky's post again. That's just good old vintage Kentucky humor. I'm pushing 70 and I'm starting to feel vintage myself. Getting aches and pains from parts I never...

    Re: 454.7.4 marine power inboard question

    Is this a factory fitting, or was it added as a flush port? What is the exact application?

    Re: 115 Mercury stalls mid throttle

    Does the fuel primer bulb build adequate pressure? Have you tried squeezing the fuel bulb while the problem occurs? If fuel system checks out all okay, then there may be a problem with spark...

    Yamaha 25 lower unit interchange

    Hi. I'm selling this unit on eBay and wondering what it will fit. Yamaha seems more difficult to determine interchange. This is a 2002 25 longshaft 2 stroke. I think it fits some of the 4 strokes...

    Re: RD-12 Trouble with new points

    Yes, you can make them work fine. Kinda like buying a scope to put on your deer rifle....gotta sight it in when your done mounting it. Then it's good for 20 years if you take care.

    Re: RD-12 Trouble with new points

    Those screws look pretty tough. The previous work was done by an ape. Points can be micro "tweeked", rarely do you see a perfect mating surface. Once set to close squarely, they should last for 20...

    Re: 1965 9.5 HP Johnson MQ-11C - Rough Idle Help

    Right, I see that pin pushed flush quite often. Just drill a shallow hole and put in any kind of steel, even a short slice off a nail. Tap it in place so it sticks up just enough to orient the...

    Re: 1985 18hp mercury no spark

    Just test for continuity across your two wires, while you move through all throttle positions. Of course with motor at rest/not running/no power. I have seen where conductors inside the wire/wires,...

    Re: 1985 18hp mercury no spark

    Welcome to the Forum. The switch boxes on these are often best tested through the process of elimination. I have had them go bad after a storage period. Make sure your trigger tests positive with the...

    I'm pretty sure it's rated at the crank until 1984 or 1985.

    Re: Advice for possible repair

    Yes, been to Lake Stevens. Duluth is a great place, can't let go of L. Superior. They say there's enough water in it to cover the surface of both North and South America with 12" of water. Or if...
