Dang - I just lost a post. I was typing/posting before I logged in.
Just last week my neighbor and I tried to buy a 2012 165 CS package. It had a 50 hp Yamaha 4stk. The seller said it have 5 hours on it. Very clean - nice (Cabelas) package (currently selling new for 17200). It had a MK trolling motor, bird, electric anchor, spare tire, and remaining warranty.
I was only 'in' because the neighbor asked me to be. Neither of us needs another boat. We got the seller down to 11500. Our final offer was 9000 - obviously it was rejected. That's okay. The idea was to sell it and make a couple of bucks.
Even at 11500 that was a nice deal. I think it must have sold - they pulled the boat from the web site.
I think that rig would be a lot better with a 70 Yamaha.
No, I'm not an attorney. Middle name is Lawton - some friends call me 'Law'. Only legal advice I give is, when in doubt, hire an attorney.
