Bought a Starcraft pontoon boat with a 2010 9.9 4 stroke evinrude ( my G'pa boat)
it it had been sitting a couple years, had trouble starting it seemed flooded (backfired and there were some minor flames although my wife considers them "major") eventually started then stalled out before we could get underway, eventually got underway but every few minutes it would stop running but fire right back up, did this several times. About the time I decided to head back it conked out for good and we rode the wind a mile back to our dock, good quality time with the missus!!!
I suspected bad fuel,drained the bowl and it did look funky. I drained the 10 gallon tank totally refilled with half a can of sea foam and reconnected. Wouldn't start despite several attempts. after dinner I knew I wouldn't be able to sleep so I went back and drained the bowl again it looked very dark almost orange but then after some bulb squeezing it started to run clear.
second attempt it fired up but while we debated casting off it died at idle and a couple attempts would not start it (I think it was flooded AND the battery was getting weak)
im pretty sure my MAIN problem is dirty contaminated gas, but I also have 2 questions
Choke: I'm an old tiller steer guy, the previous owner told me to push in the key when I turn it and this chokes the motor. I don't feel much difference if any when I push on the key. somebody said this is just making an electrical connection to an electrical choke does that make sense?
Nuetral: of course I have to start I in nuetral, but once started there's no way to up the rpms except pushing it into forward or reverse. Is that correct? Or should I be able to nudge the rpms up withOUT engaging forward?
Grandpa's 1936 1 1/2 horse evinrude is starting to look pretty good right now, I put fresh gas in that thing after it sat 35 years and it fired up second pull. (
