    OMC Cobra Shifting Issue

    Ok did some checking on what you had originally and what you have now. Best I can determine is that the change to the one switch set up occurred in 1990 so your boat may have had that originally. Up to & including 1989 they used the 2 switch set up. The brackets & associated parts are all...

    OMC Cobra Shifting Issue

    There were 2 different set ups used by OMC on the Cobras… The early models had the module & 2 switches; an interrupt switch that lowers the idle when you shift to neutral; and the overstroke switch which over-rides the interrupt switch to keep it from engaging when the drive is in gear. This can...

    Casting numbers help omc cobra 5.0 HO motor thought 1993

    The odd thing is most of the motor appears to be original OMC charcoal, except that orange which isn't even a Ford color, many Chevrolets (factory) were that color in the old days. The OMC charcoal is the correct color for that vintage OMC Cobra series. But yes what exactly are you asking here...

    383 build requirements

    ohh Bondo now there ya go, giving me ideas.... that looks great is the cam OK for marine use? what about the head gaskets and core plugs? Lol It would probably blow up my old Cobra drive, which I'm surprised is still working just fine but a V8 will fit my boat, the engine mount pads are long...

    Water leaking from engine - 5.7 GXI-E

    You know I didn't realize at first, you were the guy who had the water ingestion problem with the Chapparal right? and went through at lot trying to eliminate that. Did you ever solve it? I put Volvo style (actually was designed by OMC, Volvo just used their design) exhaust on my old '88 4.3...

    Water leaking from engine - 5.7 GXI-E

    Sorry to hear of your loss of course other things take a back seat when you have to go thru things like that. Maybe with the boat in the water you might get lucky. Here in Long Island the water never froze solid like it can when the winters were colder and salt/brackish water doesn’t freeze till...

    Water leaking from engine - 5.7 GXI-E

    I bet your answer is either one or both of these core plugs that's a huge amount of water all of it coming from the flywheel housing. And if there is water in the oil, likely the block is cracked. A forever problem with raw water cooled inboards, you forget just once you're done. Meanwhile at...

    Water leaking from engine - 5.7 GXI-E

    Sorry to say you’re goin to be pulling the engine looks like the water in the block froze and popped the freeze plug(s) in the flywheel area. No water drains there. Also you seem to have a crack in the starboard side engine mount pad.

    Can’t get outdrive fully seated

    As far as the orings, I have read that if you grease em the grease can get into the groove and make it harder to seat. I just squirt a bit of motor oil on the orings, coat the d/s splines with good marine grease and it usually goes right on after setting the gimble bearing with the tool, about...

    Can’t get outdrive fully seated

    same experience when mine has gone on that far and stops, it has always been the driveshaft splines, a little turn of the driveshaft & it slides right on.

    Can’t get outdrive fully seated

    If it’s in gear if you turn the prop slightly it might help the driveshaft splines to line up with the splines in the coupler. On my Cobra which gets installed in neutral I use a long thin screwdriver to turn the ujoints to get the splines to line up.

    Where you buy gasoline is critical.

    Same here I fuel up at Seymour’s Boatyards dock in Northport Long Island. They only sell 93 octane which is what I use. Yes more expensive but I have not had problems with water in the fuel etc.

    Very Low Compessions on Mercruiser 5.0 MPI Engine. with Exhaust Manifold, Thermostat Housing Removed.

    In fact when I blew up that picture of the intake it looks like it is ALREADY rotted through right under the thermostat. I looked at your earlier posts, that was a 2 yr old Merc reconditioned engine? and you had water in the sump? I think the source of that, could be a rotted out intake...

    Very Low Compessions on Mercruiser 5.0 MPI Engine. with Exhaust Manifold, Thermostat Housing Removed.

    Is that pic of the intake manifold with the thermostat housing removed? If so there’s a LOT of rust in the cooling passage. Did the engine have a bad overheat at some point in time? If so that could explain your compression test results. Ideally you want to do a compression test on an engine...
