    Well I found the source of water entering my bilge, look like a split in the hose that covers the lower shift cable. My boat is a 87 with a 4.3l cobra. Not sure I can get my hands into the bad area, I was thinking of a rubber cement patch? Or is it possible to seal it from the outside where...

    Outdrive to Gimble housing

    My project boat is a 20 foot cuddy with a 4.3l cobra. Recently had it in the water for an hour or so and noticed a trickle of water coming from inside the transom bracket, it is too hard to see exactly where.

    Alternator wires? 87 4.3l cobra

    Am I wrong to assume that the color of wires should match up? ie: purple/red to purple/red? Looking at the schematic it seems that the wires reverse?? Any one know for sure? or could some one check for me? Thanks in advance!!:D

    The out drive has not been run for over 3 years, was sitting on its side over the winter in my shop. Just moved it and noticed some oil leaking from around the prop shaft area.

    Spark Plugs???

    It looks like there is not much selection in the marine sport plug section, is there any reason why Automotive plugs are a bad idea?? Motor is a 92 4.3l with carb....Cheers!

    Painting Engine

    I'm getting to the final stages of my 4.3l block swap/rebuild. It seems that OMC assembled the motor minus a few hoses and such and blasted the whole thing with grey paint. Any pro's and con's that I might be overlooking would be great to hear before I go painting the thing. Cheers!

    Intake swapping?? 4.3l omc

    My doner 4.3 engine came with a 4 barrel rochester and a high rise Intake, will it be a big pain to try and use it vs. the stock low rise 2 barrel? My boat is an 87 20' cadorette. Not sure if any slight gain in power will be worth it?

    4.3 Omc vs Mercruiser 188

    I am working on a decent shape 87 20' Cadorette 200 with a omc 4.3 and a cracked block. I found a doner boat with a mid 70's ford 302/188 mercruiser. Is it worth the refit to get away from the omc stuff? It looks like there was only about 800 hrs on the 4.3, I know it will be easier to just swap...

    Engine options??

    I am working on an 87 Cadorette 200, has a 4.3l omc with a cracked block. Just wondering if there are any other GM blocks that will mate up to the outdrive? I have a line on a 350, thought it might be a nice upgrade. Any advice would be great!!
