Kicker stalls at idle speed while fishing

Quick question about kickers stalking at idle speed while in gear. I absolutely love my 2015 Merc 9.9 4 stroke kicker but I've noticed after fishing for a bit, it wants to stall while in gear at idle speed. Is that due to the plug fouling or just the idle being too low? I turned the idle screw 1/4 turn and it seemed to help a bit, but I don't want to speed up the idle cruise speed of my boat as we like to go as slow as possible. What about changing to a different plug? Maybe a hotter plug or something?

Thx

This is kinda what I was thinking. I rarely, if ever fished at idle speed. The main point of the kicker is to cover shoreline.

But if you must, maybe turn up the idle speed and get a lower pitch prop or maybe a 3 blade. Is it a fuel supply issue? Is the kicker running from a separate tank?

Correct me if I'm wrong...but on an outboard, if you want lower end push, you go down in pitch...if you go up in pitch you loose that lower end push and gain top end...so if you want to fish slower at idle wouldn't you want to go up in pitch to loose the low end push?

If most of its time is spent at low rpm, a hotter plug might be in order. If the plug is fouled, something is off. A slower pitch prop may be something to try if you are looking for slow speed. The prop may be putting too much load on the motor at the rpm's you want to run. As always, make sure the carb's clean.

try emptying the bowl on the carb. sometimes a drop of water settles in there and the motor will run at higher rpm but when you drop it down it starves because the jets don't pick up water well. I have had similar problems and one time that was it. Might not be it but its a simple thing to try.

Turn the idle adjust screw in. On my kicker I have it at idle at around 1200rpm. Manual says 900 ish. When I push it high n low fishing the plugs get some build up. On mine anyway. It's a two stroke. Even 4stroke, I'd crank up the idle slightly. Up and down will build up carbon and it'll keep running when I little higher rpm..
