I'm thinking of renting a slip for my boat this year, but the marina doesn't have gas for me to fill it up on the water. Is it too much of a hassle to carry my own fuel in? My boat is 23' with a 5.7L and holds 75 gal. I don't want to have to trailer it every time I need to put gas in it. Has...
I have a 1985 omc 5.7L motor. I don't have a thermostat in it right now because it got messed up and I took it out. I figured taking it out would just let all water flow all the time and keep it a little cool, but prevent it from overheating....but now unless I'm idling, if I run for more than...
ok I installed the pertronix ignition conversion for a prestolite dist. in my omc 800 stringer '85. It's a 5.7L. I made the diode fix to make it compatible with the ESA, but I'm not sure how to hook up the three wires from the circuit. This is the diagram for the fix...
So the saga of getting this pos to work without flaw continues, but made a huge advancement yesterday! I insallted a pertronix elec. ignition in the '86 5.7L and all my engine troubles virtually went away, runs great. The recurring problem is that the stupid gear that attaches to the upper...
I have a 1986 gm 5.7L omc engine. I ordered a pertronix ignitor kit #1181 for it and it's not the right one, I read somewhere that 1181 is the one for all gm v8's. But apparently not. This one was for a distributor with the advancing weights at the very top of the shaft, mine are at the...
I've a 1986 5.7L OMC 800 drivetrain. Right now the ignition coil is just sitting there behind the engine. Is that ok or should the ignition coil be attached and grounded to the engine block through the bracket?<br /><br />Thanks,<br />Matt
I saw one of these on a website a while back but I can't remember where it was. It was a thick metal plate that is made to be able to adapt the hole in the transom for an omc 800 to a merc alpha. It was made in production and sold for like 7 or 800 bucks. Anybody know anything about it?
hi! I have a 22' marlin empress with a dry weight of about 2940. It's on a tandem axle trailer with surge brakes. The lights aren't working real great so I'm thinking of converting to LED lights or just maybe replacing the two turn signals with LED's. Is that possible? Or do the LED's need...
my 1986 omc 800 is mechanical shift and the lower shift cable went bad, so I'm replacing it. The shifter thing inside the exhaust housing that the cable goes into has gotten me stumped.... I took off the little plate on the bottom to reveal 2 pulleys that the cables wrap around, although it...
hi!<br />I've got a 23' marlin empress with an omc 5.7 in it. The exhaust flappers in the intermediate housing have burned up and I hear you have to take the whole motor out and crap to change them, time and money are two things I don't have much of so I'm thinking of just changing it to a...
I have a 1986 23' marlin empress cuddy and am goint to try and shine it up and make it look more presentable this winter. The gelcoat is heavily oxidized, I've tried maguiars oxidation remover for gelcoats and waxed it many times but the shine only lasts a couple days, then it becomes oxidized...
a steering bracket on my '86 marlin empress broke on the lake yesterday and I have no idea how to find even what type of steering sytem it is for the parts. What broke is a bracket that goes into what looks like a gearbox that the steering piston ram connects to. It's a GM 350 with an OMC 800...
I have an '86 omc 800 that I was inspecting the other day. Lo and behold when I look at where the exhaust comes through the intermediate housing there was something jammed in there. I took it out and it looked like some kinda piece of metal covered in rubber but the rubber was pretty...
