So do you want some spacers or don't you? I've only got tomorrow or Friday to make them, past that and you'll be borrowing or buying them as I'm off on a bussiness trip on Monday for a week?

Yup thats the Yam one, the one I have is a thinner brass washer, say 8 - 10 mm which I used to go from Yam gearbox to merc props, but its in the garage and its dark

Andy,
Thanks for the offer, but I think it's going to be a no. The Yam thrust washer is quite complex, with internal and external tapers, so giving you accurate dimensions is almost impossible without knowing what we need to achieve. From what Pete says, to fit a Merc prop on a Yam, it sounds like we would need a thinner thrust washer rather than an extra washer. And the oposite for a Yam prop on a Merc.

I rang Fairweather Marine today and the chap I spoke to reckons that the Mercury and Yamaha output shafts are different dimensions and that they don't do any adapter washers. He suggested that a Laser II with a Flo-Torq hub could be re-hubbed to fit the appropriate engine type.

Don't know how it would work but I am sure you could come up with a solution!!!!

I think that's a great idea. Go for it!

What's it got to do with me though?

They are the ones that sold me the conversion washer all be it for the 4.25 gearbox hubs. (Yours are 4.5 btw).
