    White smoke(or steam) from valve covers

    1988 5.7 and not sure how many hours. When its cold and/or at idle there is a moderate amount of white smoke coming out of the valve covers if i take the oil cap off. When i ramp it up to about 1500- 2000 rpm it goes away. Is this any reason for concern? Engine always runs good, mechanically...

    ESA stalls engine

    Hello again, 1988 cobra 5.7 (standard not king). I had replaced my lower shift cable over the winter and i did it the proper way. Got all the correct measuring tools and lots of research. I'm pretty confident i installed and adjusted it properly. Goes from R to N perfect, N to Fwd perfect, but...

    Not sure how heavy oxidation is on my red boat

    I bought this checkmate boat last fall and I'm finally ready to compound and polish it. I already bought a variable speed 7" polisher and meguires 105 compound and 205 polish. A lot of the oxidation on it goes away once it gets wet (comes right back obviously) and where it doesn't go away i seem...

    Sae 30 or 10W30???

    Please don't hate me for ANOTHER oil post but i think this one is legit. So my manual calls for sae 30 (1988 5.7) HOWEVER. I noticed that the oil fill caps had gray paint on them (looks to be the exact same paint the rest of the engine is painted) and underneath the paint it says 10w30 and to...

    Yet another shift cable question

    Im in the middle of i stalling a new transom end shift cable on my 1988 5.7 cobra. Everything is going well but the adjustment tool is off. I could measure it like the manual suggests and adjust the retainer by the transom then measure the cable from the center hole to the end of the casing, but...

    OMC 5.7 timing mark

    So i have tried all the tricks and i simply can not read the timing marks on my motor, here is a picture out of my manual, i ASSUME (which is why i ask here first lol) that the part i have circled is zero. I can advance my timing light. So the manual calls for 8° BTDC so i can set it for 8° and...

    Best product for keel repair?

    I know the term "budget friendly" doesn't usually go in the marine world, but i bought a boat (88 checkmate to be exact) that someone has beached pretty regularly. Its worn to where you can start to see the fiberglass mesh. What would be a good product to patch and seal this to avoid further...

    1976 135 just known for poor idle?

    So i have a 1975 135 johnson that idles a little higher than I want it to. It runs for a short while on low idle (just enough time to put it in gear without slamming in) but stalls if i dont act fast enough and rev it back up. That being said. Last year i went through and replaced everything...

    You guys are probably getting tired of me posting about this engine, but to be fair so am I lol. Anyways I had the boat out the other day and it ran beautiful all day except toward the end. All of a sudden it started to misfire and getting progressively worse almost as if a spark plug was...

    Spark plug boot arcing 76 johnson 135

    This is in relation to my last post but I thought it would make a good fresh topic. So I had a bit of skipping with my 76 johnson 135. At this point I decided to replace all the coils. They are all the Sierra replacement kits with coil, wire, spring and boot. And on top of that I replaced all...
