    4.3 Alpha One - Gimball bearing issue

    I'm going with faulty gimbal bearing install. Doesn't look like there was water intrusion in the bellows that would rust the bearing to the shaft. Was the water in your shift shaft bellows? The rust I see is in the water passage, which is where water should be Edit: didn't see @dubs283...

    1995 Mercruiser 454 mag EFI SKI Temperature Sender

    We don't know what you're working on (same as your other post). Generally one is for the gauge and one for the alarm. Usually on the thermostat housing, tan wire

    Mercrusier 350 MAG MPI - RPM issue under a load

    Most/all 5v sensors don't operate at 0 or 5v (so somewhere in between) so that the PCM can tell if there's a disconnection/short in the circuit

    Water leaking from block but pressure tested fine?

    Aside from being undersized if it's a starter wire, what makes it unapproved?

    1998 Mercruiser 5.0 Intake manifold gasket mismatch issues

    Little salty for someone that doesn't know wtf the issue is and is soliciting free advice, no?

    2014 MPI fault codes 321 & 322

    Lazy o2 sensor could do that, not reacting quickly enough. Can you post the values at the time of the fault? Does your reader allow you to look at how quickly o2 sensor cycles, and min/Max voltages?

    Bow mount fuel tank. Balance?

    I think this might be more ballast in your boat than in most...

    Bow mount fuel tank. Balance?

    You can try moving your current tank to the bow and add some additional ballast to see how it would do

    Mercrusier 350 MAG MPI - RPM issue under a load

    If you're positive that this follows Pcms and it's reproducible when you disconnect the map, then this has to be an information problem to the PCM, right? But you need to be sure that it's reproducible (most of the time... Other times makes it seem like it's not) What's wot rpm when it's running...

    Mercruiser Alpha One Gen I Winterization

    Oof, looks like the floor is still in the way. You *can* probably reach from the front, but it will suck. Have some spare plugs handy for when you drop them in the bilge and a magnet won't pick em up. Good luck with the spark plugs.

    Mercruiser 470 Starter

    Yup, meant to follow up on this. I knew it was an auto pattern, makes sense that it's Ford. The newer 470s (3.7) do have an integrated solenoid with a slave, the earlier ones don't have the slave. Thanks for the correction.

    Mercrusier 350 MAG MPI - RPM issue under a load

    That doesn't make sense to me. Map temp should be exactly the same temp as what it is measuring, plus maybe a bit because of increased under cowling temps. Some auto pcms will lower fuel charge to account for lower air density at higher temps, though I think that that's more heavily weighted in...

    Battery discharge. ...normal?

    Ha, this solution never occurred to me. I've never owned a car or boat new enough to have a warranty.

    Mercruiser Alpha One Gen I Winterization

    The reliable reference for every aspect of maintenance and repair is the official Merc service manual for your engine. No matter how good the advice I may get from other sources, I ALWAYS cross reference with the manual

    Timing a 2 stroke '03 25 hp merc?

    Never given this engine much love, because it keeps running despite abusing it. I'm trying to set up the (remote) shift and throttle cables and set the timing. I'm embarrassed to say that I just realized I've never set the timing on a 2 stroke engine and can't figure out what I'm doing wrong...

    Almost Sunk… where do I start to salvage boat

    That wasn't their job... Most of the damage was electrolysis. I replaced *literally* (I think) every positive connection on my boat. Just finished the nav and anchor lights yesterday

    Mercruiser 8.2 w/Cats & Closed Cooling Question

    Also learning (again) what happens when you depend on unfriendly nations for your energy supplies. Energy independence is a national security issue as well as environmental. And poor mercruiser, you think they're losing money on these parts? Maybe epa or whoever could mandate that emissions...

    Light u-joint noise hard turn starboard

    You can always roll the dice...a couple of seasons ago had some knocking, pulled the drive and had a slipped u joint clip, joint was banging on the drive shaft nut. Could have been bad news if I continued to drive it.
