    Help with charging system?

    Yes. And I'm for sure getting 24v at the output terminal when running. Measured with 2 multimeters and using different ground points. But not at the battery. I agree, this doesn't make a damn bit of sense for a few reasons. I wonder if I should disconnect the orange wire and just measure from...

    Help with charging system?

    Just tested across the fuse, I have continuity. This doesn't make sense. Also forgot to mention that I did some voltage drop testing. The grounds are fine. With ignition off I'm not losing anything between the battery pos and alt orange. I'm losing a bit on the purple wire, but that's been a...

    Help with charging system?

    The black and red wires are pig tailed off the alternator 24 volts from B+, 24v at far side of fuse (starter end of orange wire), battery voltage at the red wires going to the front end of the fuse with engine running. Battery voltage everywhere with the engine off. My new alt looks the same...

    Help with charging system?

    This has persisted through 2 alternators. The one I just installed worked fine when last used. So there was a bit of corrosion inside the female ends of both harness leads. I'm going to clean them off better now that I got the boat off a (bouncy) mooring. The thing that I don't understand is why...

    Help with charging system?

    Had some fluctuating voltages last year after installing the new engine. Didn't stay very long, but would overcharge for maybe 30 sec, then undercharge. Took the boat out for the first time this season, and on the way out my voltage spiked to 18v for a minute before settling to 14.2. after a...

    1984 470 initial carb set up to get idle

    Put the motor at tdc on the compression stroke and align the rotor with the #1 plug wire. That will be close enough to start.

    Interesting. The later models appear to be different. The 3.7 and 3.7lx spec the same parts. From manual 8:

    1984 470 initial carb set up to get idle

    No. You need to increase your throttle while in neutral. Depending on your control that involves pushing a button in at the base of the handle and advancing it or pulling the handle out before advancing it. You'll never get it started otherwise.

    wont shift out of reverse mystery issue

    Yeah, "fooling around" with that adjustment rather than doing it properly always ends up as a game of whack a mole: you get one thing working and it screws up something else. If it doesn't work it means you have something worn/broken elsewhere in the system.

    Is it worth it to replace the voltage regulator?

    Took the boat out for the first time this season, went about 50 miles. On the way out my voltage spiked to 18v for a minute before settling to 14.2. after a while it dropped to battery voltage (12.7) before getting back to 14.2. on the way home it charged for a while before again dropping to...

    1984 470 initial carb set up to get idle

    The idle setting doesn't have anything to do with starting, the throttle is open and off the idle stop. When you pump the throttle that should set the choke. Confirm that the butterflies are closed. Then as dubs said crank the engine with the throttle open about ⅓ and it should start. Get the...

    470 4 barrel conversion, one cylinder missing

    Exactly. My point being that "running on 3 cylinders" might not be the same 1 cylinder not firing, tough to tell without actually testing

    470 4 barrel conversion, one cylinder missing

    Unless it isn't actually running on 3 cylinders (or misfiring on the same cylinder). A fuel related problem can make the engine run like crap and sound like it's missing.

    470 4 barrel conversion, one cylinder missing

    I think it's usually easier to rule out ignition problems first, even though they're less likely. When it's misbehaving throw a timing light on each lead. Not 100% but it will point you in the right direction. Also, hi @Eric 3.7LX Alpha 1! Haven't seen you around in a while!

    How many boats is enough?

    I bought another sunfish last fall. It's been sitting on the side of the house unnoticed until my idiot neighbor asked her about it. Same idiot neighbor that asked about our "new boat" last year--the junk hull I used for my motor swap that she didn't know about.

    How many boats is enough?

    Whenever you run out of time/space/money. My wife says we have too many boats, but I classify the kayaks as water toys and not boats. I'm losing the battle over the sunfish though "it's a SAILBOAT! It literally has BOAT in the name!"

    Longshot help for friend, '98 EFI fuel check valve?

    Turns out that the part in question was the anti siphon valve. Which is clearly a separate issue from the starting. The fuel pump sounds like a likely suspect for that...
