    Tilt solenoid issue or bad wiring?

    Cleaning everything is a good start. If the problem persists then you will need to replace the relay. If it has only 3 terminals then it is a grounded base relay. If there are 4 then the other small wire is the ground and it is not automotive.

    1972 OMC 225 Tilt not working

    It may be possible that the tilt motor could be some of the problem. The brushes may be either stuck or worn down and not contacting the commutator and arcing which also eats up the segments. The motor is Sierra # 18-6754. Also 18-0917 gasket. A short 3/8” 12 point box end wrench is the best...

    OMC 120HP suddenly backfiring when accelerating

    When you have a timing light pointing at the marks, does the timing marks hold steady when the backfiring through the carburetor happens? You did not mention replacing the spark plugs, are they new?

    1972 OMC 225 Tilt not working

    The Iwo came here to New Orleans for Mardi Gras in 93 and I got to go on board with my son and was able to take him all over the ship. The guys in the boat shop told me about the upcoming de commission. We went to Norfolk for it and had dinner with the Captain who was on it when I was. I...

    1972 OMC 225 Tilt not working

    Oh a Deck Ape! I was on the Iwo Jima from 1-66 to 1-69 then 2-69 to 8-69 on the Sedgwick County 1123 , snipe EN2. We performed logistics supporting the PBR boats in the Mekong Delta rivers that spring through summer in 69. Our home base was Vung Tau then. Remember seeing the NJ a few times...

    1972 OMC 225 Tilt not working

    It is not supposed to slip like the way you are describing. There are some parts missing. The snap ring almost looks like it may not be the original. Is it as thick as the groove it mounts in? The one that fits in there from the factory has a very tight fit in the groove and as I posted...

    1972 OMC 225 Tilt not working

    If the motor is working as you said then you should not have to remove it. The hammer blow coupling can only be removed with the tilt motor out of the way. If you can install the snap ring without a press or large vice then there are some parts missing. Try to get a parts manual. Is your...

    1972 OMC 225 Tilt not working

    There is a snap ring that holds the clutch pack and bell vill spring washers together. The only way that the snap ring can be installed is with a piece of 1 1/4” pipe about 2” long with about 1/3 of one side cut away for access to properly install the snap ring. Also the ring has a flat and...

    Testing 72 OMC 225 OUT OF WATER in

    Originally the flush out kit came with a double female garden hose adapter, a washing machine hose is better. You can run the engine all day with the flush out if you want. Be sure to have the cap on the flush out when you put the boat in the water.

    stringers black and white?

    Not unless someone painted their drive with anti fouling paint. Every one I ever saw with factory paint was white.

    Tilt/Trim backwards

    Just remember, front line to the front port on the ram. The rams are not right and left, they are both the same. The trim limit switch is mounted at the top of the gimbal ring which was designed to last about 1 month out of warranty. To replace it is a major repair job and not worth the...

    Boat stalled, later found oil in Bilge... help!

    As S D Said about the timing cover. When the engine was painted and with the harmonic balancer mounted they never received 1 drop of paint under it and also the area where the metal is spot welded on the lower flange. If you hurt the crankshaft it is no big deal to have it turned undersize and...

    Mercruiser 3.0: Dead cylinder? very sluggish!

    You probably have a worn out cam lobe. The lubricants today are not compatible with a flat tappet store cam. You have to either obtain oil with the additives or add the additives lead substitute to the oil. Sierra Marine has the oil with the additives and you can also purchase the oil from...

    replacing water intake hose and found this:

    If you raise the drive and push the drive over to the port side you will see how the hose is connected to the out side of the plastic tube with a hose clamp. The tube is sealed in the transom plate with a grommet under the flange with the 2 bolts.

    replacing water intake hose and found this:

    You might be able to gently insert a tapered tool or wood dowel stick to carefully re shape it. To replace the plastic tube you will need to pull the drive and bell housing also would be a good time to replace the bellows and water hose.

    Did you check with Crowley marine? They may have what you need. Yes the ball gear is a separate and can be pressed off. After 72 the ball gears were held on with a nut.

    OMC 2.3l Lima Engine Timing

    When the crankshaft balancer is at the TDC mark is the piston also at that point? Where is the rotor pointing at that point in relation to the #1 spark plug terminal?

    1975 351cu 233hp Mercruiser, riser block off plates or not?

    Burning out a exhaust bellow on the same side without having a overheat condition points to a restriction in the elbow/riser itself. It could be either some rust slag or even a faulty casting causing a hot spot.

    OMC 2.3l Lima Engine Timing

    You cannot beat a dwell meter for the most accurate way to set the points. The way I found best is to spin the engine with the plugs out and the coil wire grounded. If the coil wire is not grounded you will notice a different reading which will not be correct.
