    H20 coming in '86 4.3l OMC cobra

    So, first time on the water this year and BAM! Water is coming into my boat. It's not the plug. When I looked under my engine and towards the transom, it appears to have been coming in around there. When I got home, I put on the muffs and gave it a go. With engine off and muffs pumping...

    Tune up on 4.3l omc

    Still getting info on my first major tune up on my '86 4.3L OMC. How do you know when you need a new distributer or if a cap is even needed? Also, how do you know when it is time for new plug wires? I got new plugs at the end of last season, so those should be good. I should be doing a...

    fuel filter question

    In my reading of my Seloc repair manual, I came across some info on fuel filters. They recomend getting a fuel filter that has a water seperator on it, if your engine does not already have it. How can I tell if mine has one? Are they really all that important? Seloc makes them sound nice...

    Hi all, I am having hesitaion problems with my boat. I onw a '86 Crestliner with a 4.3L Chevy engine and OMC Cobra outdrive. When I "gun it," often it hesitates. This does not always happen but most of the time. If I slowly speed up I usually do not have a problem. Can anyone point me in...

    Shift cable for Cobra

    I am aware that I need a shift cable for my boat, but have a question what I need. Everyone says I need a lower shift cable. Forgive me if I sound stupid, but is that what goes from the throtle to the engine? Or should I be looking for one from the engine to the outdrive?

    Ventilation

    How important is it to have the powered vent working on an engine? My 4.3L blower has not been working for 8 yrs and nothing to my knowledge has happened because of it. Is there really much chance of the boat exploading? Just wondering how crucial it is to get this fixed.

    Shift cable and ESA module?

    I am looking for instruction on replacing my lower shift cable. I have a 4.3L GM powered OMC cobra outdrive. I am hearing that this is why my engine is quiting when I give it gas while in forward. I can go forward at the lowest possible speed, but any thing over that it sputters, shakes, and...
