1993 OMC Cobra Ford 5.0 l EFI/MPI ~ I am re-installing the sender units, oil pressure, oil pressure warning, and water temperature on a replacement engine. I found instructions on the water temperature to not put any teflon tape upon installation. I found mixed instructions on the oil pressure...
Since I have everything apart and am getting ready to install a rebuilt engine, should I take the exhaust manifolds/risers apart and inspect and replace the gaskets? They look good without any signs of leaking... The boat has about 300 hours on it... I don't want to do it if uneccesary...
Is there such a thing as break in oil? I was reading the OMC Engine Service Manual for a 1993 OMC Cobra 5.0 L EFI/MPI going over the break in procedures and they mentioned not changing the factory break in oil until after the 20 hour break in is completed... Should a rebuilt engine start with a...
Can I take all my stuff off of my 1993 OMC Cobra Ford 5.0 l (302) and swap it over to a Ford Marine 5.8l (351W) long block? If so, any conversion issues? It looks like most of the parts have the same part numbers match up except the oil pan and coupler when I looked them up on Doug Russell...
1993 OMC Cobra, 5.0 l EFI/MPI
I have had the boat out about 5 times since a lengthy transom repair and the last time out, I heard something in the motor kind of pop and then heard an intermittent ticking (like a lifter ticking). I just pulled all the plugs and found the #5 cylinder's (1st...
1993 OMC Cobra 5.0 l EFI/MPI
The last couple of times out my temp guage starts acting up once the engine is warmed up... I always start the boat and go park the trailer (wife stays with the boat), it warms up while I am parking. Once under way, the guage starts getting a little "jittery" and...
5.0 L EFI/MPI
Original wiring question... On the positive battery terminal lead there are 2 red wires, one thick guage (0-4 guage) that connects the battery to the starter and a thinner guage (10 guage) with a 50 amp fuse (has OMC part # on it) that leads to a harness in the engine compartment...
I have a 1993 Chris Craft Concept 217 BR with a 5.0 L OMC Cobra EFI MPI. I replaced all the original guages with some Faria guages I got on E-Bay. The set of Faria guages had a Voltmeter Guage and the Original guages had a Ammeter Guage. I installed the voltmeter guage where the ammeter guage...
1993 Chris Craft w/ OMC Cobra 5.0 l EFI MPI... I just finished a lengthy repair and am itching to go out on the lake. Is there any danger to boating when the water is so cold? It seems that the water would be a problem being so cold and pumping through the engine... Also, the oil in the foot...
I just finished up a lengthy transom repair... I had everything ready to go... Primed the oil pump, hitched her up and took it to the boat ramp... I backed her in and decided to run it a bit on the trailer. Before I turned the key, I opened up the engine compartment to see if it was dry. Holy...
I am refilling an almost empty tilt & trim system on a 1993 OMC Cobra 5.0 l EFi outdrive. The whole system was off the boat during a transom rebuild. The manual says to take off the cap ends of the rams and fill the low volume chambers. Is there another way? Can I fill the reservoir and pump the...

1993 Chris Craft Concept 217 BR w/ OMC 5.0 L EFI Cobra... I am putting my boat back together and am having trouble using the existing holes for the front motor mounts. I think I may be off a little on the thickness of the transom when I rebuilt it. I can pry the motor mounts back and get the...
I have a 1993 OMC Cobra 5.0 L EFI in a Chris Craft Concept 217 BR that I am re-installing. I have the manuals but can't find this info... I disconnected all the lines and did not make note of their locations... The two lines going in to the pump, one hole has "UP" (the right side), the other is...
I have a 1993 Chric Craft Concept BR 217 with a 5.0 L OMC Cobra. I am getting ready to re-install the outdrive after replacing the transom. I just remembered that the old cut out had a round area cut out at the top on both sides like the factory ran a big drill at the top two corners of the...
