If there was no obvious contamination and no overheating or other issues I would simply run the water through the top filler until water emerged clear at drain plug. I have used Radflush as Darrsi suggests where there has been rust flakes etc or residue from products like Radweld.
Quite possibly OAT coolant is good for 5 years- I was just going by Yamaha recommendations-they may of course be referring to the "old school" ethylene glycol type antifreeze.
I think some owners have issues where previously cooling system has been diluted down with tap water as a top up measure especially in hard water areas. Just my thoughts.
