    OMC: Won't shift into reverse after shop replaced upper unit

    Ok, so here I am again. Following the broken impeller shaft (http://forums.iboats.com/showthread.php?t=251629) I finally decided to have a nearby shop replace the upper unit with a rebuilt one.

    this is a follow up to this thread, http://forums.iboats.com/showthread.php?t=251629 In a nutshell, the shaft that drives the impeller broke right at the bearing. The impeller does not turn, thus engine overheats. The propeller still runs and I was able to drive the boat before it overheated...

    lower unit's fin tip broken

    ok, so I was on my trip to Door County (northern lake Michigan on Wisconsin tip) and when I was backing up from the pier off the ramp I hit a rock (no signs or warnings posted which sucks!). So, since I was going in reverse I hit the propeller directly. I busted a blade, plus the lower two...

    Problems untightening outdrive lower unit's plug

    I have a 2.3L OMC Cobra from 1990. I want to change the lower unit's oil but I can't untight the plug. I bought a screw driver with the widest flat head I found but nothing.

    Four Wins with 1990 (or 1989?) OMC Cobra 2.3L

    I just purchased a used 17' Four Wins with the above engine. I have couple questions, and seek recommendations: - Can I convert the ignition to electronic and is it worth it? - When I suddenly hit the gas the engine stalls. Sounds like the accelerator pump in the carburetor. If it is, can I fix...
