On the last trip of my season while cruising at 4,000 rpm, the motor stumbled - dropping about 300 rpm than picked back up to 4,000 about three consecutive times. I brought the motor down to idle to regroup. Throttled up to 4000 rpm and all seemed good for the rest of the trip. I pinned the last minute or so pulling into the dock and all seemed good. Plugs were done about 50hrs ago. What are these hiccups most likely attributed too? Motor has 850hrs. I do believe my battery was low - not holding a good charge, but don’t know if this would affect anything while running.
i have the software, but haven’t had the need to use it yet. What should I look for on the computer, or is the problem likely to be a simpler fix like plugs and filters?
thanks,
