Hello guys, I have a 98 Johnson 200 model# J200STLECE on a 98 Stratos 295PE that I purchased about 8 months ago.
Until now it has run flawlessly, once I learned how to start it (thank you BBC forum).
I have changed LU oil, fixed a LU leak at the bearing carrier seal, tested all the alarms (working), replaced the clear missing throttle roller (thanks again BBC), replaced the spark plugs (Champion QL78YC), primer bulb, and T-stats. All as maintenance before my issue arrived.
Last weekend it ran fine Sat, loading the boat the motor had drifted over a log, when I went to forward the prop hit the log and stalled the engine, I checked the prop, started engine and idled fine, loaded and left
Sunday motor ran fine first run, after fishing a bit, started engine to run up river, it dropped about 6-800RPM then would pick back up. Didn't want to run it so I went home, at the landing it idled but would jump now and then like an ignition miss, just sharp and sudden. Checked the compression and all between 95-100PSI on cold engine, plugs on all 6 looked fine, not white not black and fat, just a rusty brown color. Tried a timing light on all six and they were firing (not loaded, on muffs).
Back to the water next day and ran fine first run, leaving fishing idled out of a channel about 10min, trim down and hit the gas and it just struggled to get on plane, I pushed in on the fuel enrichment and it didn't help, got on plane running about half how it normally does, hit the primer again and it bogged down. It also seems to idle a little lower, maybe 100ish RPM. Still starts the same and does not stall at idle.
Thanks in advance for any advice.
