    Dock question: how do these sections hook together?

    I just bought a new lake house & it came with a roll-in dock. The sellers had already left the state so they weren't around to ask how to join the sections together. The plastic decking is flush to the aluminum frame below, and the gap looks to be too narrow to allow the thick hook to angle in...

    Recommend a good semi-permanent rtv

    All the sealants at my local auto parts stores are "ultimate_strength, everything-proof, high-temp" products. What should I be using on lower units, case halves, plastic intakes, etc that are supposed to be somewhat less than welded permanently together?

    Is a Tiny Tach a good choice for testing?

    Most tachs & timing lights need battery power. When working on smaller OBs (and other small engines) I need something quick & easy to use to read rpm. Suggestions/experiences?

    Big differences, same power?

    Today I received a service manual I'd ordered and practically on page one I'm asking WTF? How can these different years of the same outboard with very different displacement and rpm specs produce the same "BIA" power? Looks to me like the older spec was significantly rounded UP to claim 5 hp

    VRO delete -- replace pump?

    A few years ago I blocked the oil side of my fuel/oil pump per the service manual & suggestions on this forum. I recognized that the motor still has the mounts for the previous type pump and I've always wondered if it would be best to switch pumps? Does the VRO pump work at full efficiency with...

    Mariner 5M no impeller?

    I have a Mariner 5M model 661S serial 035994. Some lookups don't even accept 6-digit serials for Mariner outboards but as near as I can figure this is a 1976 5 HP made by Yamaha. It has an air shroud under the cowl and some exposed cylinder fins sticking through the lower cowl so the power head...

    Cruelty

    Why would a mfr bury something so necessary to regular maintenance? Am I supposed to remove the power head to change the plugs, fog the cylinder, etc? There's also no bowl drain on this Sea King (Chrysler).

    Are plastic props junk?

    I imagine the answer has a lot to do with the hp of the motor. I have a Force 5hp (1990 Merc) that I like for it's light weight. I've only run it in a barrel so I don't know how it performs on the lake. It has the original plastic prop. Do these flatten out under load?

    A couple basic testing questions

    SPARK I frequently read here the importance of the spark jumping 3/8" but is that with an inline tester or one that takes the place of the spark plug? COMPRESSION On my low compression Johnson 9.5 I get vastly different compression results depending on how I do it. If I pull the starter rope...

    Sea King identification

    A friend just gifted me a Montgomery Ward's Sea King 6 HP. I can't find an identification plate on the leg or bracket. How do I determine the make, model & year of this?

    What is different about newer primer bulbs?

    Last year I replaced my weathered old fuel line assembly with a brand new one and then my 2000 Johnson 40 started slowing down to an idle after a couple minutes of WOT. I check fuel level, fuel filter, tank cap and eventually put the cruddy old hose back on. Problem solved! What's the problem...

    Are Force OBs as good as others?

    This might be a touchy question... I was telling my brother-in-law on a recent fishing trip that I had brought home a near mint Force 5hp for $50 from a flea market and he replied he wouldn't take one for free. He's not usually prone to deflate egos so I'm wondering if his opinion has any...

    E/J 9.5 pump head

    This '71 9.5 I'm working on has been slowing down & stopping after a couple minutes running in a barrel. Everything checks out on this motor but I haven't got into the carb yet. It runs so well when first started I was hoping I didn't need to rebuild the carb. Somewhere in the service manual is...

    What type fuel hose?

    I was watching some OB repair videos on YouTube recently and one guru mentioned using "military-spec" fuel line. What is that? I was going to re-plumb my '71 with urethane from the local hardware store but I have to admit I would prefer black rubber hose for the vintage look IF it won't degrade...

    Need to replace outer transom board

    First of all... I assume this plate has a name but I couldn't find it. Anyways mine is crumbling so I drilled out the 4 rivets holding it to the inner transom board (itself in good condition) and removed it to use as a template. It's a scant ¼" thick so I want to replace it with a thicker piece...

    9.5 Ready for wet test

    I never wanted to become an expert at ignition testing, point gaping, timing plate removal & cleaning, impeller replacement, gearbox service, wiring repair or location parts for a 50 year old motor, but here I am. And when I return from vacation my carb rebuild kit will finally be here. I've...

    9.5 ignition plate alignment now wrong

    While tinkering with this OB the past couple weeks I've had the timing plate off at least 3 times with no problems reassembling. THIS TIME something went sideways. The carb throttle follower now wants to roll under the cam plate. I don't know what I did different but now my throttle range is...

    15hp Force the lightweight champ?

    Is the 60# 15hp Force the lightest manual start 2-stroke 15?

    Vintage 9.5: Can you set points with a timing light?

    I haven't been able to find a clear answer to this question. Almost all webpages, YouTubes and forum posts just show how to set point gap to spec but I've found a couple that mention using a timing light & the timing marks on the flywheel to verify or fine-tune each point adjustment. None have...

    9.5hp Johnson - what's this screw for?

    I'm curious the purpose of this screw on my '71. Mine is loose and has some crumbly rubber under the head like it *used* to have a purpose.
