I love that stand too. Not only what is on it! I got it for $40 when a local marina shut down. It had pipes welding on the other side to hold about 10 – 12 Mercruiser outdrives. I cut them all off, and it fits outboards perfect and is easy to roll around the garage on its big wheels.
It has a fair amount of weight on it – ’77 Merc 1500, a pair of ’57 Big Twin 35 hp, a ’49 Merc KE-7, and a ’64 Merc 110. Hard to see, but there is a parts OMC V-4 85 hp sitting on the lower platform as ballast. Probably well over a thousand pounds
