    Shift inerupt switch/throtle cable/shift cable adjustnment

    I have a 1983 MCM228 with an SEI106 sterndrive. I understand in theory how the shift interrupt switch should work, although it only engaging when the boat is in the water creating resistance on the prop is a mystery. I've watched achris's video on adjusting the shift cable and followed his...

On the lake the engine starts right up and after cruising around for a while with throttle high-low and in...

    Shift Cable Slide set screw

    1983 MCM228 engine (serial#6285627) with sterndrive serial# 6289715. I am replacing my shift cable bellows and in trying to get the set screw on the shift slide off it broke.

    I have a Mercruiser MCM228 (1983) that stopped running while on the lake. It was running well and suddenly it lost power and about 10s later died completely. It would not re-start.

    Oil capacity dilemna

    I started out with a 1983 MCM228 engine (V8-305) serial# 6285627. The block was cracked so I bought a 1978 MCM898 block (not sure of the serial # for this) and migrated all the controls from MCM228 engine to the 898 block. I believe I recall that the dipstick location was on the other side of...

    Is this sterndrive worth a 2 hour drive?

    I've been communicating with a craigslist seller who has a never used SEI sterndrive for sale at $550. He ordered it for a 1979 boat with a 228 HP Mercruiser motor and found out his transom was rotten so has never used it. I have a 1983 MCM228R (serial #6285627 ) with an "R" drive (serial...

    U-joint bellows and trim/tilt sender repair

    Two questions: I have a 1983 "R" sterndrive and am replacing the U-joint bellows and the trim/tilt sender switches and wire. The bellows I removed had a wire insert to keep the bellows (60932A4) from collapsing (I'm guessing). The OEM bellows I received did not have the wire insert nor does it...

    Thermostat sleeve

    I have a 1983 MCM228R engine where the thermostat sits under a brass sleeve and is held down by a lip on the sleeve. Every time I change the thermostat the only way I can remove it is to pry up on the sleeve and in the process destroy it. The sleeve costs $25. I was wondering if I installed the...

    I have a 1983 Wellcraft 196 Sunhatch with a MCM228R engine and "R" sterndrive. After 4 years I finally have it on the water and noticed my speedometer does not work.

    I have a 1983 Wellcraft 196 Sunhatch with a MCM228R engine.

To test the trim pump I would have to cut some wires to...
