Posting this in hopes it will be useful information for someone. (Basically trying to satisfy the requirements of 2 seperate companies)
Okay so for starters i have a 1988 OMC 350 that someone before me had installed a petronix ignitor II electronic ignition paired with a .7ohm msd blaster coil...
I think i got my ESA issue solved, (will find out once in the water) long story short i changed a .7ohm coil to a 3ohm coil so we'll see how that works out. ANYWAYS i have a timing question. I have the engine timed at 8° btdc as the manual says. As you can see in the attached pictures total...
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...
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...
Prop swap. Hub kit?
Hi everyone, I'm currently trying to change out my original 19 pitch prop with a 21 pitch. Im replacing the omc prop with another omc. The new prop is "deeper" than the old and the trust washer is a pretty sloppy fit in the the new one as where the old one it fits freely...
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...
So i want so wet sand my boat in the near future to remove oxidation. I want to do it right and there's an awesome video on youtube to show you how it's done https://youtu.be/ZexSavaT4tY and when he is done wet sanding he uses 3M marine high gloss gelcoat compound 06025. Great stuff im sure and...
Okay so im going to make a PB and i have a sheet of CSM that I'm planning to cut up and add to the mixture (total boat epoxy resin) along with fumed silica for a thickener. Is this okay? If not what would be a good alternative to the CSM? Im going to fill in gouges in my keel. Dont care about...
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...
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...
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...
So i have a boat with some spots in the keel worn bad enough that some fiberglass is exposed due to the precious owner beaching it a lot. Anyways. I want to make a peanutbutter out of total boat epoxy resin with slow hardener, fumed silica, and chopped fiberglass. My plan is to prep the area...
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...
So i stumbled across this and it is very close to my home town. I dont know too much about these and was wondering if i should go for it. Here is the ebay link https://m.ebay.com/itm/Performance-Concord-speedboat-300XP-Outboard/292703255365?hash=item4426793b45:g:muoAAOSwx0Fbhzqr
let me know...
Always loved OMC but this one is really testing my faith. 1976 johnson 135. So... compression. 105psi in all cylinders except for #2 which was 115psi. Just rebuilt the carburetors with all new gaskets needles and seats. I have spark on all 4. Hopefully the timing is right.. i have no clue at...
