I think GoHarley is a little optimistic with his $6K figure. If you can get that much for it, take it immediately! Maybe GoHarley will pony up the $$. \:\)

If it were me, I'd be happy to get $5K for such a vessel and would likely accept something close to $4K.

Pick up a copy of Boat Trader or go to boattraderonline.com and search for jet sleds, jet boats, jet pumps, etc., and you can find somewhat comparable crafts, tho I don't think I've ever seen anything that old.

Just my 2 cents, but I've made sled shopping a hobby for the last few years and think I have a decent handle on prices around the NW.
