Mercruiser TR upper gear sets

[Senor Falcon]

Hi All,

I'm looking for 2 sets of Mercruiser TR 1.5:1 upper gear sets, 17/17. They were used in the TR commercial drive (see attached file, page 4).

I would prefer new ones but second hand would be considered, if in good condition.

If anyone has any, or can suggest where I can find them. Please let me know.

Thanks

Peter
