Still $37 a foot where I am in the yacht club. Safe Harbors got bought out so you know the marinas are going up up up. For me the yacht club was the ticket.
1,) Chair. Check out the Llebroc line of chairs for the helm chair. They build them for GW. Won't sell you the exact chair, but they sell the same model without the GW do-dads. Taller, seat folds as a bolster, high back and excellent arms. The GW chairs prior to the new ones by Pompanette...
First thing I'd do it hit them with WD40. When mine sticks or is intermittent I do this and they pop back to life. Happens about every other year. Now as part of my pre-storage items I hit the one on the binnacle and the two individual ones.
If the motors are pre 3006, the coating Yamaha used back then is suspect. Once you see aluminum, it will wear. You likely get 5 or more years but eventually, if the top is breached the motor is toast.
It's a common problem. The meter is bad. You can't get the exact meter anymore. You have to order a kit. You'd have to cut the panel to make it fit. I chose to live with it. It says 120VAC maybe put a sticker one it if It bugs you.
Small screws near the weep holes and then push up. You'll see how easy they are to recover when you get em off. Monel staples, fabric and foam. Can get the fabric, foam and other stuff online.
Ask for pics and do your dilligence with short time members or few posts. There have been scammers here before...
I'd def contact A&J. They do them for GW and will know the boat.
My experience with the website is in the middle of the two above. A tad slow and expensive. I did a custom logo with a local shop and had my own sweatshirts done.
