Cats were originally powered by two 13 hp Nanni
diesel engines. The saildrives, marketed under the Nanni name (the
product literature calls it Nanni 2.6 SD. for 12 to 90 hp) had gear
boxes manufactured by Hurth. Hurth, however, has been bought and sold
since these boxes were manufactured and no records of these
transmissions have survived. Many of today's boats are still running
with the same power plant and Nanni saildrives.
Nanni ceased to market these engines and saildrives in
the early '90's. Acquiring parts and zincs are a problem. Nani will
happily sell you a zinc for $200. + freight - A bit pricy if you ask me.
Other prices for the remaining available parts are
comparable. Shaft seal for the sail drive, a $10 item cost $100 from
Nanni's U.S. distributor.
I have had zincs machined
to fit these SD1 Saildrives. Contact the Webmaster for availability
and price. "O" ring sets and seals are also available.

parts available HERE .
One owner has solved the engine parts problem by
manufactured under the Beta Marine label.
http://www.betamarinenc.com/ The Beta is a marinized version of the
ubiquitous Kubota diesel.
Folding propellers by Gori Propeller
were standard equipment. They are still supported by Gori.
I have not yet found a mechanic who has any knowledge of
the Nanni 2.6 SD saildrive or the transmission.
