Just bought a Grady 27 Sailfish with twin 225TXRA Yamahas.Want to service motors.Crankcase and gear oil.Is Yamaha oil a must?What type of gear oil? Synthetic oil for motors?Does not specify in owners manuel just gives oil weight.Want to do service myself to save a little gas money.Also where can I get a pump to get oil out.Thanks for any info guys:smiley:
