Hello gents! Newbie here and needing some feedback to troubleshoot an older outboard before I invest $$$.
Symptoms/background:
2002 Johnson J150PLSNF
Carbs haven’t been cleaned/rebuild 5+ yrs
Evidence of gas (not much) on the bottom (inside cowling) after storing for extended time
Motor never fails to start but at times it would shut off at idle at the dock
After stopping to fish, at times, takes a few tries to start. After starting, would have to put in gear and push on throttle to keep engine from dying (would be okay thereafter)
I’ve noticed engine only runs around 5000rpm at WOT. At times, it would spike to 5500 which would run really well (significant MPH increase) and then at other times <5000rpm.
Not sure if this is related, but the past few times, false alarm of “No Oil” comes on. This happens in the morning and would be fine for the duration of the trip.
Any insight is appreciated. I’m thinking of getting the carbs rebuild first, meaning I need 6 kits correct? Also thinking about getting new fuel lines.
Thanks!
