    1997 7.4 mercruiser mpi blue water inboard

    I guess it depends on the transmission to provide left and right propeller rotation. I cannot imagine both propellers turning the same rotation. Now I am curious. Does Merc have transmissions that provide L&R propeller rotation? If it was a Volvo then it is easy to have both standard...

    1997 7.4 mercruiser mpi blue water inboard

    Wherever you go if you decide on a rebuild be very sure that they are familiar with reverse rotation engines. As well as keeping the port and starboard engines‘s parts separate.

    454 vibrating and breaking starter bolts

    The un counter weighted balancer is probably from a small block engine that are internally balanced. A good thing that you found the problem. I had that exact engine and I remember the balancer along with the countered flywheel.

    5.7 slave cylinder wiring

    The black wire may have been connected to the slave solenoid on the “I” terminal to provide a ground. Try to start the engine with the wire disconnected, if it does turn over then the wire goes somewhere else. If the slave solenoid does not engage then connect the black wire to the “I”...

    1985 volvo penta aq 280 tilt trim limit switch

    If the trim sender is the type that has a cable going down through the transom plate and attaches to the suspension fork you are lucky it lasted this long. It has a stainless wire covered with plastic that eventually goes away and binds in the sealing grommet. You can try removing the sender...

    Mercruiser 200 V8 Alpha 1 MR Drive

    Another place to look at is the water hose from the bell housing to the gimbal housing.

    Installing new bellows

    The inside of the bellows is tight where the outer surface of the universal joint coupler passes through. Put some grease on the coupler and rotate the coupler with a suitable tool until the shaft engages the engine coupler, by then the drive should be able to go all the way in.

    Selectrim-Abandon or hook back up?

    The solenoids always gave a lot of trouble. If they have 4 terminals then they are non grounded base types. They look just like automotive styles but will not work since the “I“ terminal is hot when the solenoid is triggered and since it is connected to a ground wire which burns out the...

    Selectrim-Abandon or hook back up?

    The holders get weak and I have had a few times where the fuse would check for continuity but not passing any current and yet not showing any signs of being burned. Another problem is where they are in relation to the engine cover’s closing, the holders are supposed to be water proof but...

    Selectrim-Abandon or hook back up?

    Just be sure that the rams are sealed and not leaking. Sometimes the cover that retains the piston will be cracked. Do not worry about travel of the rams. When the engine is back in the boat be sure that the engine does not “lean over” to one side when the rams are at the end of travel. You...

    Stumbling at Cruising Speed - OMC 5.8L

    There should be a removable cover for access to the tank sending unit where the fuel hose is attached. If the tank ever has to be removed the deck will have to be cut. A dwell meter is the best way to get the points set. Then recheck the timing.

    Stumbling at Cruising Speed - OMC 5.8L

    Get a 6 gallon outboard tank and and first run the boat on the main tank until it starts running bad. Switch to the 6 gallon tank and see how it does. Most likely your problem is the suction tube in the tank. There is a fine filter in the tube that will have some debris in it. You need to...

    1991 Rinker seems like it runs out of fuel.

    I feel confidant that the problem may be with the fuel tank. The suction tube in the tank probably has a very fine tapered filter in the tube. They get clogged easy over time. Un screw the 90* fitting from the tank, the tube unscrews from the fitting, push a coat hanger wire through it to...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    It is easier to work on the hydraulics with the engine out of the boat. Just cycle the system a few times and the rams will both be fully retracted. Power steering fluid is good as atf tends to foam easily.

    Tilt/trim pump

    The wire colors are simple, green as in grass down, blue as the sky for up. If the pump runs at full speed and the solenoids just click when the pump does not run then there is good chance the solenoids are at fault. If your pump has the miniature style solenoids they are not as good as the...

    Selectrim-Abandon or hook back up?

    Try to run the pump by jumping from the battery, if it runs all the better. If it does not most probably the brushes are stuck in their holder. While holding the field frame down gently remove the cover, there may be a small ball bearing on the end of the armature. Stick the ball bearing with...

    Mercruiser 5.7L competition ski squealing noise when driving under load randomly

    The rattling noise is the flex plate which is no real problem. The squeal could be the outer ring of the harmonic balancer. Or if there a buildup of black belt dust on the engine? If the outer ring is not slipping try dis connecting the alternator wire to see if the noise goes away. If...

    Mercruiser 215E

    Try to find an Alpha 1 driveline set up. The transom plate assembly is the most important. Even if the drive is from a 4 cylinder you can easily change the upper gear set. The exhaust may have to be routed straight out depending on your current manifolds. The 2 vertical bolts that attach the...
