Never ending...
Last week the SJ90 wouldn't start after sitting on a beach fishing for an hour, and looking under the hood noticed fuel pouring out the sound atenuator. Thank goodness for a trolling motor!
Took the carbs off (based on other posts) and found the reddish 'sludge' in the vent lines, cleaned them out so they can be blown thru/sucked thru without restriction, found a small flake in the 2nd carb float/needle seat, and made sure all 3 floats were in tact and float after soaking. Turned carbs upside down and blew in fuel inlet and verified not able to blow through. Put everything back together and adjusted the synch bar so the butterfly was closed at nuetral and evenly flat at full throttle. Good news was that she fired right away (in the water) but died after 20 seconds of running...no gas pouring out the carbs (atenuator still off). Won't start again. Tested for spark...spark on all 3 cylinders.
Now I notice that cranking is slowing down quickly so I put the charger on overnight, dropped it in the water the next morning, and it tried to fire but wouldn't start, then seemed to not even try to fire. Each time trying to crank, cranking slowed down...seemed like battery going dead.
Today, purchased new battery, made sure it tested good (900+ cranking amps and 12.7 Volts), took it to the water and it cranked good for a few attempts, but then started slowing down with each subsequent crank until it wouldn't hardly turn...very slowly when it did. Ugh! Pulled all 3 plugs and verified cylinders didn't have any water in them (hydrolock), then to the parts store for some more testing.
Testing included all 3 plugs getting spark, the part store tester saying the starter was good (drawing 160 amps), 12.67 volts at the battery at rest, 12.0 volts at the battery while cranking (cranked fast out of the water). Checked voltage at starter while cranking...11.8 volts. Still cranking fast. Replaced positive cable with a heavier and shorter cable just to be sure and checked ground and all connections around batter/starter/solenoid.
Took back to the boat ramp and tried to start and it seemed to only crank a couple of times at fast speed then quickly reduced crank speed til barely spinning/not spinning. Frustrated and headed back home...pulled 3 plugs, all 3 fuel-wet but look ok. Suggestions? What do I check now? Starter starting to die is the only thing I can think of....positive/negative wires didn't feel warm after cranking either...B.O.A.T = <B>reak <O>ut <A>nother <T>housand-- lol!
