    New day New Problem--1988 GM 5.7/Cobra oil at the plug wells---

    I noticed after my break in oil change that I seemed to be using or leaking oil. When I changed the cap rotor and wires I saw what was to me an alarming amount of fresh oil in the bilge. I cleaned the bilge and started the engine running on muffs in its stall . With a good light and engine...

    I currently have my electric choke wired to the side of my coil . I have read somewhere that it is not correctly connected by doing this.

    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...

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...

    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...

    I may or may not have screwed up the threads on some of the studs on my transom plate/gimble ring studs. If i can not salvage the studs and have to replace the ring , can I use a transom setup from a 4 cyl or should i only use a unit from a v8 ?
