A few years ago, for the bigger motors, I found the deal wasn't good enough to entice me ... unless you know someone in the shop who owes you a favour. They save all the low hour best quality ones for their boat/motor combos or for VIPs....for Joe Public off the street it was a motor with 1000 hours on it for a 10-20% off. Not worth it, if that's half the motor's life (the good half!). The one that has 14 hours and is half price, ok, now you're talking!
The other issue was who runs the motors. If a self-guided lodge, you know they've been abused. For guided lodges, apparently the motors with computers get better treatment. Because the lodges review the reports and give the guides the business if they are abusing them -- like trolling on the main motor instead of the kicker.
I like a good bargain, but at the time it didn't entice me.
