Yes i read the coolant label on reservoir and i put gallon and half of dex cool in it. I have the zr409 motor. I had it winterized by a shop. Was trying to save money but de winterize it my self c asuse they wanted 485 to de winterize it thought it was way crazy. i found that they took the coolant hose offthe cooler and i put all plugs back it and i used a device to run off water hose. It had good flowwater temp never got over 82 degrees. While i was putting plug b asck into transmission i rotated it buy hand it has a squeal noise when u rotate buy hand is that normal trans fluid full . Is there grease cert i might over looked? Thsnk you for your help this is my first boat of this type had it new since 2015 still trying to learn all the systems it has to offer
