Yamaha 20hp lower unit interchangability?

[tomjack]

I have a 1986 20 hp short shaft and can't find which other hp models will interchange. If anyone knows, would you please let me know? Thanks!

I've been seeing a bunch of 15hp lower units for sale - does anybody know if these are interchangeable with the 20? Thanks

It would help if you posted your model #

You can look up the lower unit for youor and compare it to other motors to see if they are same part #

Must not be a US model as I do not see a 20hp in 86

I just realized that myself. I bought it in Canada, so obviously they had different product offerings up there.
