    OMC oil change Problems---- wrong filter ?

    I finally ran the boat long enough to put a few hours on the new 5.7 engine so I wanted to change the oil and get the break in oil out . I bought a Cobra Marine Filter some time back that was advertised as being for a 5.7 engine . Well although it threaded on just fine it leaks like a sieve...

    1988 5.7 OMC Cobra--ESA Influence

    Took my boat fishing yesterday with a couple of shirttail relations and began to have a few bugs show up in engine performance . After tooling out past the 5 mph buoy I opened up the throttle and had one pop and a miss now and then , when I backed off a little it ran smoothly . That was the only...

    battery question

    I put a new 31 series battery in the boat a few months ago that I bought at Wally World and fully charged it now reads 11.27 volts. I used two different meters and both read the same. The engine starts fine , it seems to hold a charge and I have not really had any problems yet. Should I return...

    Omc Cobra shift problems---- 5.7 1988

    Just when I thought I was done with this project I find that I still have a shifting problem. I replaced the engine and transom shift cable and used the OMC jigs to set the cable up so I know it's right. I adjusted the control cable according to Wolfs directions . I can shift into gear 9 both...

    my new old 1988 ss20v

    Took the side guides off and replaced what was rotten and rapped em in some new marine carpet. I think the plan will be to finish out the buffing ( I may try some color sanding at the bow to see if i can get rid of the rock chips ) and then roll under the trailer and take the staples out of...

    OMC Cobra failure to start .

    I have got my boat to the point where I need to start and run the engine as well as test the shifting adjustments that I have made after a new transom cable was installed. I set the Tsm cable up with the OMC jig but after assembly would not shift into reverse . I thought I had solved that...

    my new old 1988 ss20v

    Well , as usual the minute I got out the paint the wind came up ! I don't know what it is around here but it's as if some one with the power to control the wind is watching and just waiting to fire up the wind when I start to paint something on this boat. :confused: Anyway It is what it is now...

    I've got my pivot loose and the transom shift cable off to replace the O ring on the cable end. I noticed that he bell-crank was not turning freely so I pulled it apart , inspected it , cleaned it again and then put it back together again. Now , when I tighten the keeper bolt it will not turn at...

    How important is the " O" ring on an OMC transom shift Cable

    As usual I got in a hurry the other day and installed the lower shift cable on my 1988 OMC Cobra and left the O ring off of the brass nut in the pivot. How important is the O ring , would it hurt anything if I left it out or should I pull the pivot and cable and install the new O ring...
