OK, so quick background. I have a 2010 235 with 5.0MPI. I purchased the boat new in June 2010.. has run great and started easy until last time out at end of season. The boat had been sitting for 2 weeks without running, lots of rain, went to start and battery was weak. Figured it was from the bilge pump running. Charged the battery, went to start, cranked great but would not fire. Checked things out, like kill switch up, good connection at battery, looked for loose wires..nothing, cranked great - no fire. Did what I shouldn't, hit it with a little starter fluid and it started, ran a little rough for a minute then seemed fine. Let it warm up, shut it off, let it sit for 10 minutes, started it again - no issue - drove around the lake and pulled the boat. Changed oil, cleaned it and put it away for winter.
Fast forward to this spring, the weather was getting nice, so I charged the battery and re-installed, stated the clean up for going back into the water, buffed the boat like a mad man, listened to the stereo while I worked on it. Yesterday, I pulled the boat out of the garage, put the muffs on it to do the first start of the season, hit the key and the motor turned over very slowly - battery was weak?? Thought I had run the stereo too much, so put the charger back on for an hour, turned the charger to "start position" and hit the key. Motor cranked great... but no fire. Again, checked all the obvious.. nothing. Did what I shouldn't do, hit it with a little starter fluid, nothing, stopped and called the mechanic to set an appointment for him to come out.
Left the charger on for another hour, had a solid 12-13 volts. Just went out and checked, down to 10-11 volts ( this is according to my battery gauge on dash.. not a meter).
So what gives, nothing was on and the battery was discharging?
Do I possibly have a bad battery... could this be the start issue?
