More than a good price for a Suzuki, Mariner or Evinrude 50, that's for sure!
One dealer on the South coast last year was quoting £3,600 for a new Evinrude E-Tec 50hp which had a list price of around £4,800
Another was prepared to part with a new Suzi 50 for £3,800, which has a similar RRP to the 'Rude.
If you're talking 4-stroke, be aware that Yamaha brought out a new 50 last year with Efi. You could well be able to find a dealer who's stuck with one of the carburettor versions and would be prepared to do a deal. Only last month I was looking for a new Yamaha Malta 3hp engine which Yamaha stopped building about 2 years ago. Convinced I'd only ever find a second hand one, I made a last ditch phone call to one of their best dealers, Liverpool Power Boats. Imagine my surprise when the girl on the phone said they had a brand new shiny one literally hanging up in the showroom window!! It was only one of two left in the country
