    Mercruiser 3.0 Engine knocking noise

    I am beginning to think that the flywheel might be loose. I cannot imagine an engine making that much noise for that long without finally coming apart.

    Mercruiser 3.0 Engine knocking noise

    If I read your description right you stated that this noise has been present for 10 years? Or has it started as a result of water entering from the manifold? The engine appears to be idling rougher than normal. 3.0s normally idle slightly rougher than a 2.5. It almost sounds like the rear...

    MOTOR SWAP

    Do you have a Stringer mount drive, Cobra or the later joint venture OMC/Volvo? Try to locate a rebuildable 5.7 core that has the same flywheel bolt pattern.

    VP 280 no reverse

    As Dubs283 posted about cable travel. If you still have the instructions from the control would be helpful. If not try down loading it. At least try measuring the total cable travel from full forward to full reverse. I am going to guess that you should have 3” total travel which I bet you do...

    Transom Bearing Plate Leak

    If it only leaks with a flush out on the drive and the engine running on dry land then the “Y” pipe is the culprit. If it does not leak then the transom itself is the problem.

    Transom Bearing Plate Leak

    There is a good chance the wood in the transom is soft and the water is coming in under the outer transom shield. In other words, the transom has to be replaced. The engine and drive system have to be removed and the boat has to go to a fiberglass shop. $$$

    After you replace the timing belt remove the spark plugs and spin the engine with the starter or with a wrench a few times to check if the timing marks on the belt “walk” back to the original location when you first installed it. It take around 25 revoloutions to get the marks back to the...

    Stuck Defective Grease Fitting on Lower Unit

    The thread pitch on grease fittings is 1/4”-28. You will need a bottoming tap to clear the threads. A starting tap will end up damaging the threads because of the pointed starting feature.

    Outdrive cannot clean

    Be sure that the bonding wire from the inner transom plate to the tiller bar is in good condition. Also that the engine is bonded to the transom inner plate.

    Did you remove all the threaded plugs in the Venturi body? Some have fine mesh screens on them. I have had good results cleaning out those carburetors in the past. The Volvo service manual is very good and helpful with setting the throttle levers evenly.

    Google Dometic straight rack cables. There might be a universal cable rack that fits your helm. The thread pitch is universal so you do not have to worry about that.

    1971 StarCraft holiday

    Your cable looks like a Det mar . The cable and rack were usually sold as 1 piece. It looks like some company called Dometic may have bought out Det mar many years ago. You will have to buy a complete new helm/cable kit. To be sure for a correct cable length fit, measure the length of the...

    Most likely the cable is binding inside the tube on the inner transom plate. what color is the steering cable outer jacket? If you look closely the length of the cable is printed on the jacket. Is the helm under the panel round or straight. You will need a new cable but first it will help to...

    Are you sure that the throttle plates are synchronized ? If one is opening more than the other it will act like that. If the carburetors are working correctly the idle mixture screws should be a 1.5 turns out from lightly seated. Any large deviation from that then the carburetor has a problem.

    Older Ranger Inboard

    It could be either a Waukesha, Holman Moody, or even a Genuine Volvo. The main thing is it has the adapter housing, along with the external brackets for a small block Ford. As Scott said lets see some pictures.

    The 4“O” rings under the pump can also be obtained from a NAPA store. They have them in a box by size and can be matched up. Before you reinstall the block put a straight edge across the bolt holes, you will see that the block is distorted. Mount it in a vise and with a good file smooth it...

    Replacing ignition on old 165hp GM inline-6

    There was a HEI that came on the last production inline 6 truck and other GMs that used the inline 6 engines. They require a solid 12 volts along with a 12gauge wire. It has a tachometer output also.

    Replacing ignition on old 165hp GM inline-6

    The 18-5519 from sierra would be my choice. It comes with a coil and spark plug wires. Your original distributor by now has a worn out bushing and no lower bushing. The lower distributor shaft bushing in the block above the oil pump should be worn out also unless the engine was recently...
