    Crud in carburetor, is it a problem?

    Water in the tank can absolutely do that. Also if that crud in the carb is in the right place, you can be running lean with those symptoms. I'd start by either running off a jerry can and/or disconnecting your fuel line at the carb and run it into a container to see what your gas looks like...

    Outdrive Alignment

    Don't miss the point here that the drive will go on if you force it on, but your alignment will still be off, which can lead to engine coupler failure. I'd be worried that your mechanic is going to focus on just getting the drive on, rather than fixing alignment. In fact, I'd just have him align...

    Lower Unit compatibility question

    🤷‍♂️ As long as the op knows the difference. People will frequently say "lower unit" when talking about the entire drive.

    Outdrive Alignment

    A. The alignment tool will bottom out, you can't insert it too far. B. Your gimbal bearing probably isn't out of alignment your engine is. Did you adjust the mounts at all? C. "Not hitting the drive hard enough". You can hit the drive as hard as you want, but it won't align it.

    Lower Unit compatibility question

    He never responded to @Bondo about what exactly he was replacing, if "lower" meant "stern drive" then he'll need to reprop. And since he specified the gear ratio... $250 gets me complete out drives around here. I'd be wary of just buying the lower anyway for fear of what happened to the upper.

    Lower Unit compatibility question

    Assuming you're coming from a 1.84 drive, you'll probably need to reprop. You should have some wiggle room if you have a 19 now

    What pitch prop do you have on there now?

    Nola Mike's 3.7/470 --> 4.3L swap thread

    Alright, boating season not quite done yet! I think my tach wasn't adjusted correctly. I think it was set for v8, but the v6 setting was between clicks on the adjustment, if that makes sense. Got it so that it now reads consistently 150 rpm higher than the digital tach. Today I hit wot at 4750...

    Mercruiser 470 low compression on cylinder #4

    So... Your next step should be a leak down test, maybe you can see where you're losing compression. It does sound like rings--if you had a water leak into #4 then you definitely could have damaged the cylinder. you half assed the push rods, so tough to totally rule that out, but didn't sound...

    Mercruiser alpha one small amount of water in shift cable housing

    What are you working on? A1G1 drive, if it's never been done needs the shift shaft bushing and seal replaced.

    Alpha one Gen 2 u-joints

    Why did you remove everything from the input shaft?

    Is this the aluminum head 470.

    There's no such thing as a reliable 30 year boat with an unknown history.

    Is this the aluminum head 470.

    Agreed, you'll still get a performance boost over what you have.

    Is this the aluminum head 470.

    No? How much?

    Is this the aluminum head 470.

    Get a 3.0 and lose 40 hp. What's the upside?
  18. nola mike

    Is this the aluminum head 470.

    Yeah, 6 month swap being the operative term. I've been completely unimpressed with the 4.3 so far in terms of everything except refinement. Definitely not worth the effort unless I can get some performance gains out of it. If it gets me up on a slalom then I'll be happy, but I'm not optimistic...

    For discussion, mercruiser v6 , rochester, edelbrock

    What would make the pressure all of a sudden jump on a mechanical pump? I'd still think of carp in the needle seat, would clean it out and run it in a remote tank to check.

    No Power at Ignition or Instrument Panel

    As always, since you didn't specify what you're working on, we'll assume that your wiring is identical to mine. You should have a red/purple wire to the ignition switch. The purple supplies the gauges and the ignition when the key is in the run position. So check power coming into the switch...
