2001 Johnson 90 PLSIG. Same as PLSID. No idea what the G is for.
Motor starts easily and will never stall at idle when cold.
I literally could launch the boat and idle in gear through a no wake zone for 20 miles without stalling.
Example of my problem:
I run 3 miles to the reef.
I turn the motor off while catching bait.
The longer the motor is off, the more likely the following happens(but it always happens to some degree):
Motor becomes more difficult to start(although always starts).
I always have to completely prime the fuel system in this situation. I can feel that there is no fuel(soft bulb) and I have to completely pump fuel from the tank to refill carbs. I can feel all the fuel that I am having to prime.
Once restarted, I usually get smoke(more smoke than a cold start) and have to advance the throttle in neutral until motor seems to have enough fuel.
If I accelerate slowly I stall. Bumping the key will cause the motor to stall immediately.
If i accelerate quickly, I can run all day long. For example, I have never once stalled after a long run back to the ramp. I can wait in neutral for a ramp to open up, or I can idle around in gear indefinitely without stalling. If I turned the engine in the water at the ramp, I would have same problem.
When I run the outboard on the hose, it idles at about 800 RPM after the quickstart feature disengages.
In gear on the water, my idle is between 500 and 600 rpm in gear. This seems low.
Carbs are clean.
Plugs are new.
Compression has remained at 120 on all 4 for 2.5 years(3 tests).
No leaks from carbs(new bowls)
No leaks from vapor separator(new gasket)
Boat get used very frequently(always has fresh treated gas)
VRO is disabled and I premix 50/1
Motor runs flawlessly other than this.
Motor has done this from day 1. There has been a random day or two when this problem didn't occur.
Thanks in advance for any help and suggestions.
