I have a chance to pick up a pair of 225 4 stroke Merc a- has from a buddy. My question is that I know these are essentially Yamahas painted black but what about living with them now? Are there parts available from Merc? Would I have to go to Yamaha for service? Can I use Merc controls or can I use Yamaha controls?<br /><br />These motors have HIGH hours 700+ but they are always serviced and he only wants to get rid of them so he can sell the Hull. Everyone is scared of the hours but I know that well maintained equipment keeps running. <br /><br />Thoughts?<br />Mac
