I change the oil and lower unit in my BF90 myself. The manual says to replace the o-ring washer on the plugs each time. I can't find these listed anywere. My dealer is a two hour drive. Anyone know where I can get these via phone/web/mail order?

Thanks to all

..or a good sized autoparts store. They usually have a selection of orings. The Honda probably has a metric oring, but you can pick a standard US size thats slightly smaller in diameter and it should work just fine. I've never looked at the Honda Plug, but if its about the same size as Merc or OMC you could try an OMC/Bombardier dealer and they may have an or-ring that will fit also. They use them on some of their lower unit fill plugs and also on their fuel line connections.

My BF90, a '97 model, has a Honda (from Japan) engine, but a Merc (of Canada) lower unit. Then it was assembled in Georgia. It takes Merc prop shaft seals and Merc water pump impellers.

Thanks guys. Your suggestions started me looking in different places. I found an assortment at Northern Tool at a good price.
