    Bellow replacement job

    Ok will check the shift cable before disassembly. Was my understanding it should shift smoothly with very little effort, I assume this is with drive on? Is there any guidance you can give on checking u joints? They move freely but don't seem that tight? Boat only has about 325 hrs and the...

    Impeller- Red paint- remove before removing screws??

    Most Volvo engines are painted red except the ones that are grey or black.. Can t see how much paint is on them but would think if you lightly tap them socket on it would be fine. I think kennys comment about compression test is accurate. To be honest usually best done before you by the...

    Bellow replacement job

    Yeah I figured basically all day ... How do you leave shift cable mostly in the boat ? Take the end off at the bellhousing ? can the bellhousing slide off it? thanks

    yes this is fine depending on how level the boat is parked you will not have equal flow out of the ports

    Mercruiser 3.0 No Spark issues

    I have seen a lot of negative comments but I have run them in the past. Had a 17 ft with 3.0l that it improved getting on plane especially with a skiier. Eventually it broke of my cavitation plate it was attached to. My advice is try the boat with it on and off an make your own decision...

    Engine dies after 40 minutes

    Who knows you it is possible it changes color at the cannon plug, but if you disconnect at the coil it should be irrelevant for testing unless the tach is reducing the voltage on the 12 ignition on circuit

    2003 5.0 MPI problems

    I believe 43 psi or so would suspect possible pump or fuel pressure regulator issues

    Engine dies after 40 minutes

    Not sure the history of the boat but had a similar issue with my brothers center console last year. Ran fine in the fall when put to bed, wouldn’t start in spring. Was able to jump the engine (yam outboard) at the cannon plug would run and start. Ran a jumper from boat harness at motor up to...

    Water Streaming from Weep Hole After Impeller Change

    Yes this build up probably blocked the flow... make sure it stays clean otherwise it can crack the housing if it freezes in winter

    Can the base of engine work? Two to bolts under engine are rusted and can

    I think you just disconnect the wires at the shift interrupt. Since it worked then it didn't suddenly, do you have a kill switch at the helm that may be tripped- do you have 12v at positive terminal of coil when cranking To rule out a back fire (when spark plug fires but intake valve is open)...

    Engine dies after 40 minutes

    Ok if you are confident it has gas would look for spark loss with a spark gap tester when this happens both off the coil ad at the plugs and definitely disconnect the tach wire at the coil. Maybe you can rig a test light off the 12v supply to the coil so you can see when it happens if you have...

    Engine dies after 40 minutes

    When this happens have you stopped and pulled a couple plugs to see what they look like? I assume when it happens and you stab the throttle fuel is being squirted out of the accelerator pump nozzles?

    Can the base of engine work? Two to bolts under engine are rusted and can

    That sounds more like a lean sneeze than a backfire. Are you sure its getting gas? check for gas and spark should fire? Also verify the shift interrupt switch is not active as that will ground the spark

    Mercruiser Alpha 1 vs SEI

    Unless you have mechanical coverage under your plan i dont think it will be covered, but doesn’t hurt to ask. a lot of folks use SEI with good results. They do have a good warranty. On an older model boat i would think thats the intelligent choice vs rebuilding or new OEM. alternatively you may...
