    Still no power

    The sea water pump. Start there, that's what supplies constant cooling water to the manifolds/risers, obviously it's not working. Very common to replace the impeller, it's part of routine maintenance. You say the t stat is 160, that's what the motor should run at and your temp gauge should...

    SX-A Outdrive Tilt motor shorting...Ground wire hot.

    I suppose, you will need to test the individual parts of the system to isolate the issue

    SX-A Outdrive Tilt motor shorting...Ground wire hot.

    Find the broken wire, it's shorting something on the ground side, getting full amps from somewhere, doesn't have to be part of what you replaced either, could be part of the relay housing and associated wiring to/from it and the pump

    Removed raw water pump - rotated harmonic balancer…now what?

    Shouldn't matter. But you may need to clock the pump assy once installed to line up the support arm from the block

    5.0 Mercruiser Problems

    Even without the pur/wht wire grounded you should be able to be within the range on the timing marks when looked at with a timing light. Are you for sure on #1 cylinder wire? Furthest fwd cylinder port side of engine Kinda confused as to what you have done so far. You say you've checked stuff...

    Shift cutout switch not working even after replacement

    Have you tested the old or new switch for continuity? Possible there is a damaged/unconnected wire somewhere. Depending on the vintage and style of ignition system on your motor the wire could go to either the coil or distributor

    Bellow replacement job

    Most likely the cable is worn and needs replaced. By removing and installing it the way suggested most likely took what little life was left in it I figure if you're going to do the u joint bellows, which requires removing the bell housing, just do everything back there. It's the same amount of...

    Help finding the part number

    I can't recall immediately if the sx-m bell housing has a continuity strap, I work on so few of those transom assys. The bellows don't suffer near as quick a fate as mercs Its possible there is no strap for the bell housing and Volvo relies on the anodes/continuity to the drive for protection...

    Mercruiser 3.0 Exhaust Riser Leak / Compatibility?

    Didn't even notice that at first glance. Fwd fastener appears loose too OP, you need to get the riser/elbow installed correctly with the proper gasket before further diagnosis. That boot does not look familiar but some oem exhaust boots have a similar appearance. Don't know if that one is...

    Help finding the part number

    Volvo uses a continuity strap for the bellows and water passage hose clamps. Possibly one or more of the ends has broken off

    7.4mpi just started running rough and with gas coming out exhaust

    Not that I recall however it is quite possible. This is why an ohms test on the harness is your next step. Check for a short to ground first on all injector leads, with injectors connected/unconnected, key on/off, etc.... As stated yes, the ecm uses "batch fire" for the injectors, one...

    A soap/water solution in a spray bottle will show leak(s) right quick

    Volvo Penta 5.0 GL-B does not go properly

    Sounds like a fuel supply issue. Something in the tank randomly blocking the pickup comes to mind based on your observations

    Still no power

    And you wanted to tear into the motor to check timing gears? You need to be thorough with troubleshooting, had been posted many times prior to your jumping to conclusions. Glad you got it figured out. Again, be pragmatic about this issue, double check your work on the manifold/riser r and r...

    2003 Mercruiser 5.0 fuel pump challenge

    Understood, as others mentioned the safety lanyard switch (run/off) on the remote/dash is for the ignition. Neutral safety is located in the remote for mcm/sterndrive applications. It's not a manual operated switch, the shifter mechanism engages it when not in neutral. Check the stickies, top...

    5.0GLPWTR, fuel pump question

    Volvo electric fuel pumps are known to make more noise than other brands but will squeal quite loud when about to fail. If yours makes no noise when 12 (+) volts is directly applied its a safe bet the pump has failed. Keep in mind its a good idea to inspect the entire fuel system too, filters...
