Hi all. I have an 88 3.0 Cobra with 985268 model outdrive blown. I have a line on a solid known good marked as for a 3.0 liter with model 985684.
Is this a compatible swap? I have OMC manual and it makes no reference to this model drive for any year or displacement. The tag says 3.0 liter...
Hi all. 1988 Cobra 3.0. New impeller done at start of season. It didn't fail just routine maintenance. I had left my radio on and drained battery so I jump started at dock and let it idle for 10-15 min. Noticed temp gauge heading for the red and shut it down. My repairman came down and...
All: A question... I need to change tilt / trim cylinders on my 88 Cobra. I assume I need to do this in the down position. I have both the OMC and Seloc manuals and they aren't clear on this, however.
The OMC manual is clear that you should be in the up position to check or add fluid, so...
I am trying to improve performance on my boat, and believe a prop upgrade is in order.
Here is current setup:
1988 OMC Cobra, 3.0L
17 foot Renken SS1700, 1988
Running a 13x19 prop now.
WOT rating for the engine is around 4500 per manual.
The boat runs right at 4500 at WOT, but only at...
Hi guys.
Have an 88 Renken 1700, stern drive. Recent acquisition. In the floor of the boat I have a ski / rope storage well. It is not draining water into the bilge after rain and such. There is a drain hole in the back of it, which I have lightly poked around in to no avail. My gas tank is...
Hi guys
Have a 1967 Johnson, 80 horse V4 electric shift. Trying to match controls to it, looking at a control from a 40 HP 1962 Johnson, by photos it looks close but not sure it will match up. Can anyone offer an informed opinion?
The controls and shift wiring with the motor have been hacked...
Hi gang.. got an 88 OMC Cobra I/O set up on my Renken bowrider. I am trying to find out if there is a way to install a tilt / trim indicator gauge on the dash. Been searching around and can't find anything on the subject.
I am hoping that maybe the outdrive has the sensors present and all I need...
Hi guys. Just picked up a nice little 88 17 ft Renken bowrider with a 3.0 OMC sterndrive.... Needs a steering cable though.
My question is this... I took the numbers off the existing cable ( still installed in boat) figuring I could match it up pretty easily.
The numbers on the cable are

My son inadvertently installed the battery with the cables reversed on my 71 Johnson 60ESL71C. <br />I know this fries the rectifier, and after correcting the condition, checked the charging output and it was dead. Replaced rectifier, and it now charges well. Used the boat last weekend without...
Any of you know what the compression should be on a '71 60ESL71C three cyl?<br />My Seloc manual does not seem to list the spec. I am guessing somewhere around 100 PSI, but if anyone can confirm that, thanks. Heading up the lake tonight and would like to run a test when I get there.<br /><br...
Hi guys. Running the above motor, and it runs great till you get above 4500 RPM ( 5000 is max<br />It starts bogging out. I am thinking "fuel starvation", as it is absolutely perfect at lower speeds, have no stalling or idling issues.<br />I had my daughter sit in back and pump the primer bulb...
Hello all:<br />I am rebuilding a spare electric shift lower unit for my 71 Johnson 60. <br />I am one part away from being done, it's a wavy washer that goes on top of the shift solenoids before you bolt the cover onto them. <br />OMC part number is 314126.<br /><br />If anyone has a line on...
I have the above mentioned motor. I came across a working OMC tilt trim unit removed from a 69 Evinrude Triumph ( same basic motor I think).<br />Can anyone confirm that this tilt/trim would fit my motor? <br /><br />Thanks folks....
Joe, or anyone else... Have a lower unit for 68 Evinrude, 55HP, electric shift. Need solenoids for shift mechanism... Is OMC 580776 the correct solenoid assembly for this unit? I think it is... but would like to be sure....<br /><br /><br />Thanks<br /><br />Craig
