I have 2 2000 130 outboards on my Glacier Bay catamaran. One suddenly decided it doesn’t want to start anymore. Coughs snd sputters, runs for a couple seconds then dies. I have two engines and swapped a lot of parts. I hooked up a small portable tank with 3 gallons of fresh gas. I live in Florida and use her at least once a month in the keys. She’s been out of the water about two months.
new:
spark plugs
Oil and filter
new gas from a separate 3 gallon portable tank
new fuel filter. The small plastic one in the front of the engine.
cleaned snd checked for thermostat. Opens at 70c
swapped with my other engine:
VSP tank. Drained a d swapped
fuel pump on the back, cam driven
the sensor above the thermostat
the sensor on the exhaust above the VSP
pulled off the intake shroud
sprayed MAS cleaner inside intake
so I did some winter work, topped off the tanks from 1/3 each and went to ramp. Starboard won’t turn over. Tries and dies.
cylinder pressure. 150 140 190 200. 3 is the low cylinder.
brand new plugs get dark with carbon after a day of cranking.
yep. That’s not good at all. But is it the cause of my woes?
pretty sure each plug is firing. I pulled each after an attempt and all were warm, not quite hot. But they get dark with dry carbon. I soaked cylinders overnight with Quicksilver Power Tune. Got about 0-5 psi improvement. Not a lot.
yes. The kill switch is in just baffled. One cylinder is low, but won’t start ? Clean gas. Good fuel pressure and brand new plugs. Friend thinks maybe an exhaust leak because the plugs got carbon covered so fast .
any easy suggestions short of a blown gasket, cracked head or bad valve ? Seems where that a month ago we started so easy and now suddenly won’t start. Fuses are good. Tapped the relay box but don’t know what those relays are for.
