Re: 1989 Yamaha 30
no there was a bulliten put out years ago to remove the sticker and mix 50:1. as far as what to look for ask if its been in salt water and if so has it been flushed and cleaned with fresh water after each use ask when water pump was replaced last you should do it every season. check prop seal that its not leaking. other than that look at overall condition to see if it was taken care of. good luck hope its a good one
