I have a 1972ish long shaft 20 for 1/5 of your budget.
It has the cowl off a 25, and we are open to negotiation.
Do a search on this section. Details in a previous thread. I'm on the phone here otherwise I'd post a link.
This comment will make more sense when you read the original thread- I should add when we bought it we though we had bought a 25 and only when sat alongside a real 25 did it all become clear. We had been done.
In summary its old but is cheap. It has tiller, but can also supply remotes.
