is a 1980 model 23hp, so it's about 35yrs old.
Looks good though.
can be hard to come by, maintenance parts
I dont think I would use this engine
is SA, if it isnt it pristine condition.
I would use a engine based on mitsubishi (vetus/Sole/Craftsman/..) or Kubota
(Nanna/Beta/Uniersal/..) industrial engine, as internal parts are avaiable throughout the world in tractor shops. Marine
spesific parts are often interchangeable between brands.
I got a universal M-12 kubota engine and use a Nanni 2.10 salt water
