    Mercruiser Setting Timing on 3.0L

    never done a 3.0, but even as a novice it won't take you a full day. likely most of the people on here giving advice have done a bunch of head gaskets (we're old). in general you want a good quality auto gasket. marine just means not carbon steel. composite or SS should be fine. very cursory...

    Merc 350 bolt v 2 barrel carb fluctuating RPMS

    have you put a timing light on the wire(s) while having the problem to verify that you're getting a consistent spark? if you are having a misfire, it's on multiple cylinders...

    Fuel Tank incorrectly labelled?

    You could also have a crack/hole in the pickup such that it won't draw when the fuel is below the level of the crack. Easiest would be to pull the sender and have a look.

    Shift cable bellows.

    Good to hear, easier to see what's going on when you're in there.

    Bizarre IAC reading

    idk. yeah you'd think the idle would increase or there'd be rough running. then again you say it's fully open but screenshot is fully closed, so not sure what's really going on

    Bizarre IAC reading

    Vacuum on my last 2 engines have been comparable to car values. I'm 18 mmhg at idle, but you need to make sure that timing and idle are within spec to get reliable values. if you are at 12 (and it's a steady reading--what the vacuum does as the engine runs is important) that would go along with...

    Shift cable bellows.

    Still don't think you're getting it. You need to have tension on the prop and lower shift shaft AS YOU REASSEMBLE. Let's make it simple. Remove the whole drive, split it, and redo.

    Shift cable bellows.

    well, no, but without the prop locked the shaft will slip and flop around a bit.

    Shift cable bellows.

    But are they mated correctly? They both need to be in the same gear when mated, which is why the prop needs to be locked.

    Shift cable bellows.

    Not sure if we're all just misunderstanding or you are, but if the lower is not in forward gear but the upper is (ie the shaft is facing forward), the intermediate shaft will be misaligned when you put it back together

    MC-1 Drive Dog failure?

    That cable needs to have nearly zero resistance to work right before strange things happen. It has to really bind to trip the cutout on the hard. It takes much less of a bind to mess with the shifting in the water.

    Shift cable bellows.

    the prop locks but you need to keep tension on the cable. it will slip out of gear if not.
  16. nola mike

    Shift cable bellows.

    Yes, but it should still lock in one direction at least. I'd take the whole drive off, and if it isn't shifting correctly then, split the drive.

    Boat had been stored for 19 years

    It's strange having to think that the running gear is the easy part, but it absolutely is. No way to flip this boat unless you part it out if the floor is rotten (in which case you might get $1-1.5k). Even a basic floor redo if the stringers and transom are solid is $500+ and a lot of effort...

    Mercruiser 3.0 won't "lock in"

    probably won't need a gimbal puller (and I don't know that I'd replace it if it's good, though wouldn't fault you for it). with the engine out it's easy to knock out from the inside.

    MPI Starting

    where is the choke on an mpi?

    Shift cable bellows.

    Not knowing what you did, it's certainly possible to screw up the shifting when you split the drive or not engage the shift rod when reinstalling it. Does it lock in the other direction when you pull the cable out?
