I just purchased a 10' Avon rib that came with two fiberglass seats and flip up launching wheels for $100.00 (US) it needs one new valve and a couple of patches but is useable. I can not find any data on the site or the web as to max HP rating. I am guesing 8-10 based on the AVON ERB310. It has a fiberglass sole instead of aluminum decking as on the ERB and the tubes are grey while the hull is biegeish. The transom has an cast aluminum motor plate inboard and wood outboard. The serial number is AV886697K990. Any other insight about the boat would be helpful. Thanks in advance.
