Ia few months ago I bought a new 60hp 4 stroke efi merc from a dealer suppose to be new old stock. It squeals at low rpm from 1500 to 2200 I seen on threads something about a bushing above lower unit needs greased The only bushing i could see was clear at top of drive shaft housing, To high to access from bottom there was a triangle opening in drive shaft housing but no bushing. I took to mechanic and he hooked to computer and read 8 hrs on engine which is what my hr meter read.I sprayed some marine grease with ttp at access right below power head no change motor was manufactured in 2019 according to sticker on engine serial # 1c600009. I installed new black max prop 14x11 when bought new. Any suggestions Thanks
