    1989 5.7 omc propeller not spinning

    In the meantime try to remove the swim step which will be a big help for when you start replacing the cable and re installing the drive. You will also need a 1/2” Allen wrench to unscrew the pivot housing bolts. Add a new drive shaft bellows to your parts to replace also.

    1989 5.7 omc propeller not spinning

    First get a genuine OMC service manual for the model number that you posted. Disconnect the lower shift cable and try pulling and pushing to see if the drive can be shifted. Sometimes the propeller shop did not press the hub all the way in. Is the thrust washer on backwards? When was the last...

    First time pulling an engine questions

    With the flywheel housing on a drill press you should be able to drill out the broken bolts. The engine mount “feet” might be saved after sand blasting, you probably have a torch to heat up the nuts to free them up. The threaded part can be replaced with generic ones. Also a good time to find...

    With the rams off the drive have you tried running them in with the pump? If you still hear the noise then the packing glands on the rams need to be replaced. It is a easy job and the parts are not expensive.

    1987 Volvo penta aq125a starting problems

    You need to find out if it is running out of gas or is the ignition spark going away. One thing that helps the Bayliner/Volvo start. Is to add a wire from the extra male spade on the starter solenoid to the + side of the coil. That way there is 12 volts delivered to the coil in cranking mode.

    First time pulling an engine questions

    Sometimes trying to weld up spots on a rusted pan will leak because the metal tends to crack when cooling. The 2 part epoxy will be easier and will seal up the rust spots. Another way is flowing solder over the bad spots after cleaning with muratic acid. If you are referring to the sealing...

    Replaced Bellows now gears won't engage fully?

    Use a piece of 1/4”npt pipe as a gauge to select the right size drill bit so that you do not take out too much. A hog nose punch will catch and drive out the remainder of the brass fitting. Even if the threads get banged up some just run a 1/4” npt pipe tap into the hole. It does not take...

    Replaced Bellows now gears won't engage fully?

    Try using a blunt punch that is just under the outer diameter of the cable jacket. Try to drive the remains of the cable forward and out. the wire in the cable jacket is almost impossible to drill out and just dulls the drill bit. If you manage to get the remains out then drilling the rest of...

    Best home generator?

    Here in S Louisiana whole home generators are pretty common. When the power is out for maybe a week or more they are worth it. I went all in with a Cummins/Onan 25k. Within 300’ of my house there are 6 whole house generators. The problem at some houses there were some exhaust gas...

    The bellows has at least another year left so it is still good.

    First time pulling an engine questions

    The outer leading edge of the bearing retainer compresses against the bellows. The bellows is easy to change if you want to by just removing the worm clamp, with a screwdriver pry the rear inner lips inwards, raise up the pivot housing then tie it so it will stay up and remove the bellows.

    5.7 Mercruiser Starter problem

    It appears that the starter is kicking out in a “false start” mode. I wonder if the same thing will occur with the coil wire out of the distributor cap. If it continues to turn over then then I think it would rule out a mechanical issue. Also with a remote starter button that you may already...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    OMC was the first with the dipstick/oil withdraw tube. If the core plugs are plain steel then your assumption is probably right about the engine was in a salvage yard in the past. Nice job on the engine hoist.

    Everything done but low rpm at WOT. Distributor spring?

    There might be a small wire spring retainer inside the top of the rotor shaft that has to be expanded slightly to lift the reluctor. Also there is a shift override switch that by passes the shift assist module. After the drive is in forward disconnect the module and try to get the boat on plane.

    Everything done but low rpm at WOT. Distributor spring?

    If you cannot locate the correct springs you can get a complete distributor from Sierra Marine. The carburetor is the original marine Holley ? Is the electronic shift assist system still in place and connected to the distributor? 18-5481Flame Thrower 18-5482 Flame Thrower Both are for 351-460

    First time pulling an engine questions

    Your description about the rear mounts is correct along with the front. It is the opposite of the #2 posting describing the Mercruiser set up. The 2 1/2” 13 nuts come off and of course the lag screws on the front mounts. Disconnect the fuel, battery cables, power steering, wire harness plug...
