I have dual 2000 ox66 yamaha 225 on 27 sailfish....sent to shop to have the engines looked at prior to season and received a call that i have low compression reading number 5 cylinder and they want to do a rebuild with new lower end either with yamaha or jasper....also that it will cost about 6k ...i need some feedback on this as the motors have only 450 hours and the engine ran perfectly prior to pullout his year....did some research and compression 10% less than other cylinders is no big deal....also would ringfree help or any other remedies other than a rebuild.....am confused at this point and need some guidance....thanks in advance
