Thanks, Yeah I think that's it, I had trouble finding it on boats for some reason. My only concern is I have the K5 model and boats only seems to have K4 and earlier, most likely the same transmission but would need to confirm. Anyway I'm probably fussing over nothing, the drive is still working fine and going full speed, just making a few odd noises from time to time it didn't used to.
Had to order some new rear wheels from boats this week, one of mine the tyre is ripped and coming off. Machine has 200 hours on it now. Only US$20 for a pair, I'm sure that means over $100 from Honda Australia
Something good I found out to yesterday- Honda dealer here in Brisbane I found knocks $100 off the price of a new 217 if you're a contractor, good to know.
