i picked up an older boat a couple years ago. it has ran very well until now. i picked it up from the marina that stored/winterized it and i heard a slight whining kind of sound from the motor when i put it in drive. i didnt think much of it but about an hour later the boat would not go into gear. i had to drive it back in reverse. the marina says it sounds like a bad lower unit and i should pull it out and bring it in. my question is how do i know if this thing was winterized properly? it ran great when it came out of the water and now an hour later (of use) my lower unit makes noise and could be shot?
please give me some feedback!!
