    1989 E88MSLCER No Spark Cylinder 4

    That solved it, replaced power pack with OEM and all 4 coils, also replaced all plugs with the QL77JC4's gapped .035, starts up on the first cylinder that comes to the top every time again. Must have been weak spark throughout, idle jumped up to 1600 or roughly +700 RPM on the initial start with...

    1989 E88MSLCER No Spark Cylinder 4

    Hi guys, Just got off the water the motor felt sluggish. Did a spark test and had no spark on #4. I replaced the coil, no joy. I then swapped coil charge input from #2 to # 4 had good spark, verifying the new coil was good. Am I suspecting the power pack not sending charge voltage? or something...

    1989 E88MSLCER Spark Plug and Gap Question

    Thank you for the info, as the bz's in it seem to be functioning well I think I will keep them as my default. I'm not to concerned with plug life, so will keep them at 1mm. It is a small price to pay for having a motor that starts on half a crank, and runs all day... I will just keep a note in...

    1989 E88MSLCER Spark Plug and Gap Question

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    Notching the valves and reaming the air escape hole seems to have worked. Ran the motor on the hose both heads settled in at 145(p)-150(s) with 20 minute runtime, with no overheat alarm. Temp cycled with t-stats on both and t-stats housing reflected head temps so gonna conclude that this issue...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    I am guessing you are correct... after replacing all parts I was finally able to test today for the leak... No leak Pump seems very strong telltale the most I've ever seen from it. test 1 Started with both hoses left off, both heads running strong flow of water. Put hoses on started motor...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    Thank you very much for the help... I had replaced the entire pump this spring, I think the turbulent removal of the motor may have dislodged or broken something. The motor was salted in bad all screws caked and the base gasket had been leaking at some point freezing the motor and base with...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    New day new problem I think... Both Heads completely descaled. Both head gaskets replaced and heads torqued to 20 ft/lbs on the bench. I have not retorqued the heads yet after the run gonna wait till morning. I installed the motor to the outboard exhaust housing, torqued everything to spec... I...

    1989 Evinrude 88SPL (E88MSLCER) Cooling

    I cleaned up slightly the jacket cover I replaced (It was cracked at the spark plug hole in 2 places and pitting looked to be almost completely through one of the channels) so I never bothered to even clean it (just ordered a used one on eBay that was fresh water use) and a different type gasket...

    1989 Evinrude 88SPL (E88MSLCER) Cooling

    Also want to note the 2 holes in the Head Gasket to the Block (supposedly designed to supply water to the jackets) centered top and bottom have no associated pathway to the water jackets on these heads. They simply dump back into the ring an inch away from the 2 supply holes through the gasket...

    1989 Evinrude 88SPL (E88MSLCER) Cooling

    I have searched everywhere I can think of. If there ever was a gasket that was cut to allow water from the head to come in contact with the cover, it must have been discontinued long ago. I can find only the one image (attached in an earlier post) that shows a gasket that would allow water...

    1989 Evinrude 88SPL (E88MSLCER) Cooling

    It's hard when the first time you do something you have no idea what the original gasket looked like... Then the placement of the part seems to show no way for water to get there... Then the questions, is it the wrong gasket, wrong covers... why isn't this making sense etc etc Sorry for being...

    1989 Evinrude 88SPL (E88MSLCER) Cooling

    I have researched gaskets all the way up to 120hp in all years surrounding 1989 they all look like the one I have. My theory now is the gasket broke allowed channels to clog, water always takes the path of least resistance... So it was overheating because the water was basically going from...

    1989 Evinrude 88SPL (E88MSLCER) Cooling

    I can look all I want, water is not getting to that cover through a solid gasket.

    Thank you, so it's not just me. There is no way for that cover to get water.
