Changing fluids and filters on my 250 Yamaha

[Mylo]

What oil do you use? Owners manuel just says 4 stroke motor oil. Do you use Yamaha products or does it matter. What weight? Grease, Motor oil, lower unit oil. Oh ya, filters too. Fuel and oil.

best thing to do is pop the cowl and find out which inline fuel filter you have. get the yamalube, yamaha oil filter, inline fuel filter, and water seperator. i run the merc synthetic gear lube. make sure you get the two o rings for the lower unit fill and drain screws. I use amsoil grease but lubrimatic is fine also. make sure to remove prop and smear a little on the prop shaft, then retorque prop. this is also a good time to give under the cowl a good dose of 656. i buy it in the gallon jug and use a spray bottle.

Sim yamaha is a good place on line to get the parts if you don't have a dealer near by.


good luck. They're really easy motors to service yourself.
