few weeks ago I went out to do some trolling and my main motor wouldn't go fast. it kept bogging down. So I took my time getting out deep and trolled 5hrs and used the kicker after getting out there. Periodically I would turn on the main for a few min. After 5 hrs of trolling I turned off the kicker and turned on the main. It worked no problem, no bogging got up to 40mph (on way out would only go 9mph at most). Now yesterday after a 12hr day on the lake (and driving 3hrs to get there) my dumb tired @ss didn't put the throttle in neutral all the way when I turned off the ignition as I got to the dock. Well, I tried to restart it right there and only heard a click sound, tried again and another click, again this time no sounds. Anyone else do this to their motor and know what damage they may have done or if this is a simple fix? I also noticed the tell tale took 20 seconds to come out of the hole so that's concerning me now too. I just got the kicker this feb, wish I got it yrs ago then the main wouldn't be having bog downs and tell tale concerns.
