    Doohickey

    That's not a doohickey, that's a doo dad. I'm thinking "we need a photo". At least on quite old nav light I had used a "then somewhat standard" automotive general purpose trailer light / etc plug, round, 2 prong Or maybe cut off both ends, or the boat end, and buy one or two...

    Hook up boat engine to permanent magnet generator.

    ^^I was referring to the comment about PM generators^^ I was 18 in 1966 and was just as happy to see the DC generators "go"

    Hook up boat engine to permanent magnet generator.

    So far as the new Ford hybrid trucks (there's an ad bragging about powering your house) I don't recall, but seems to me there's some nonsense that the transmission/ electric drive motor is involved to produce enough power From here: When activated, current travels from the battery to...

    Hook up boat engine to permanent magnet generator.

    Actually I know of no vehicles from "the 60's" which used PM generators, except smaller bikes that used a magneto style alternator. Generators (that is older automotive generators) produce power by retaining a certain amount of magnetism in the iron based core. This is why...

    Check your furnace filter

    What you have posted here is FAR worse that just a lack of heat. If the heat pump is running under reduced air conditions (in heat mode) the head pressure/ temperatures will be very high. This is very hard on the compressor and will contribute to short life. One of the banes of heat...

    Chaparral backfiring a lacks power

    Don't discount the possibility of basic things like low spark energy (failing coil, etc) or a worn flat cam lobe. It DOES happen

    Second fuel tank

    Can't do that. When one pickup tube comes up for air---that is what it will suck. Frankly, even on my little junk 15' old Crestliner, I like to run two complete tanks/ hoses. Swap back at the outboard. This gives you redundency if the hose/ primer/ connectors should develop a...

    Slow speed needle valve for 1971 25hp Johnson

    I think I would try to "dress" the tip. If you have a lathe/ drill press chuck it up. To protect the threads, use your head. One way is to get a straw--even if too large--and gently slit the straw lengthwise for a short bit. Use a small file, emery board, sandpaper backed by a...

    54 johnson 3hp

    Most old OMC's all need pretty much the same thing, assuming the rings/ bores aren't worn badly, or water intrusion into the cylinders/ crankcase, or damage to reeds, etc If new enough (about the model year in this thread) to have the "newer" epoxy coils from then into the 70's...

    Windows 11 yes/no?

    THIS. Learn to use linux. I run mostly Thinkpad T520 laptops dual boot with various Windows (whch I don't use) and with mostly Linux "Mint" with "Mate" desktop. 'Mint' is a takeoff from Ubuntu, and "Mate" is a type of desktop which sorta resembles the old W98/ XP style...

    LED safety issue

    As a long time radio amateur (who is no longer very active) I "fight" this kind of thing all the time. Many MANY components we deal with every day affect radio reception at some level. AT HF one of the worst offenders in my home was my old cellphone charger--a tiny switch mode...

    Merc 470 no crank

    It's a sad sad commentary. In a previous life (mid seventies for 15 years) I sold auto parts, heavy hardware/ rigging, hydraulic hoses and more. NOW a days, NAPA, Oh'Reallys and others, have no decent catalogs and the computers are just like Google......zero help. Trying to find...

    Propane BBQ Grill Repair question

    If the manifold is correctly identified, all it consists of is a tube and the orifices. You should be able to disconnect it from the burners and the gas connection and examine and clean it if necessary.....soft wire through the orifices, or pressure solvent such as carb cleaner...

    Did not know where--ANYone find source for Merc-O-Tronic documentation/ diagrams?

    Did not know where to put this........... I have two Merc-O-Tronic analyzers, both need some attention. I have tried reaching the company, IE the Phlakebook account and phone number, and finally got what seems like an automated response. Has ANYONE got even wiring diagrams/...

    Im going the wrong way!

    WOW I did not know this.........I'm assuming this is how some boats achieve counter rotation rather than reverse rotation engines?

    1960 Evinrude 18

    I would at least yank the flywheel or if it has an inspection port (on top of flywheel) inspect coils for cracking epoxy. ALL the old OMC coils crack from the new style "universal mag" until someone replaced the coils later. Condensers are suspect. Likely 80% or more that I test...

    Angels shaking out their Dandruff.

    But where are you? Here in the N end of Idaho we've had it "easy" so far--unless you own a ski hill. They are complaining. And around here you never know. Some of the worst winters we've had did not get underway until into January.

    Electronic or points coils

    Follow the COIL manufacturers destructions for ballast resistor. Some coils such as used with GM HEI draw much more current when used with points. And coils "truly" engineered for CDI such as MSD are quite different from old school "points" coils. Having said that, with...
