    Alpha One Gen 2 prop shaft seal replacement

    The best way to remove the threaded ring is to drill a 3/16” hole roughly 2”apart as close to he gearcase as possible then chisel it out. The tightening tool tool could be made with some 1/4” key stock welded to piece of pipe large enough to fit inside the ring then use a pipe wrench. However...

    1976 American 18 OMC 235 stringer winterizing

    On both sides of the block, and on the bottom of the manifolds there may be either butterfly style drains or rubber caps held on with worm clamps. Quite often the drain cocks are stopped up with sand or dirt, you may have to remove the whole drain valve. Or blow them out with compressed air...

    Alpha One Gen 2 prop shaft seal replacement

    The 5 Star marine seal puller/installer kit will do the job but @ $700.00 probably not worth the investment. I had one of those when I had my shop, it was not nearly as expensive then. It did pay for itself then.

    2004 Volvo Penta SX-M1 Outdrive Cracked Bellows.

    You better take it apart right now. Just like SD posted. If the shaft, gimbal bearing and gimbal housing corrode together you will be spending some real $ to get it straightened out.

    Mercruiser 3.0 12" and 14" flywheel interchangeable

    If the spare couplers are the style that are triangular in shape that had 3 mounting points then they should bolt to your flywheel. The kind you cannot use are the type that bolted to the 6 crankshaft studs that mount the flywheel.

    loss of power over 3500 RPMS FYI

    Have you ever tried using a 6 gallon outboard tank? That will narrow down the problem to either point to the tank or the engine’s fuel system.

    Buying a used boat with Mercruiser 228

    Raw water cooled should indicate close to 160* or less at all rpms. With the drive down in the water in neutral, steer lock to lock and listen for drive line noise that changes.

    Burning ~3 quarts of oil between changes

    One thing I learned about PCV valves. Years ago my son had a 86 Crown Victoria. It would belch out oil smoke from time to time. Turned out the cure was a genuine Ford PCV solved the problem. One of the mechanics at the local Ford dealer told me to try one.

    SX-M Drain Hole

    Just remove the dip stick and try a 3/8” 16 bolt. If it screws in easy then the drain will be the same.

    1976 OMC stringer electric control box removal

    What makes you think that the switch is at fault? There is a feed from the ignition side which will be red or purple, 2 white wires which are the neutral start, if there are green and blue wires, green is “go,” blue is “back up.”

    1976 OMC stringer electric control box removal

    To separate the control from the mounting bezel get a punch and a hammer and un screw the center ring nut, it is a right hand thread. A few taps usually will loosen it. I believe there are some of those tubular switches on e bay. First check it with an ohm meter, the problem may be elsware.

    Is this raw water pump serviceable?

    You never mentioned that you were in the UK. I now understand your plight. If you have the tools and ability then take a shot at repairing It. Here in the “colonies” we are spoiled with lower prices for those type of things.
