Yamaha F250 TXRD maintenance

[wyn]

I just bought a boat that has F250 TXRD and did not get an owners manuel or maintenance schedule. The motors have about 500 hours on them. What schuduled maintenance should I do besides engine oil change, lower unit oil change, fuel filters, and water pump impellar? Thanks
