Jet unit for 1991 2-stroke 90hp

[Trout248]

Picked up a 1991 90hp 2-stroke. Did not come with the lower unit.

I'm wanting to build this into a jet. Couple questions on the jets, did yamaha or is yamaha making their own units?

Any places around to find either a used or new unit? Can't seen to find them locally, and I live in a place where there are lots of jets.

Any help tracking one down would be great, or leads

Thanks

With your 20in shaft motor, the jet unit adds about 5in for the transom you will need, so about 25in.

Last I heard, new jet units were close to 2k, might want to keep an eye on ebay and make some contacts with the jet boaters in your area.
