I am looking at a the above mentioned boat. The boat has 8v53n and the owner claims 7ghp at 9knots and 21gph at 17 knots and 2400 rpm. Are these accurate numbers or is that per engine. Would the boat track straight at 9knots. Not sure of engine hours how is the the reliability of the 8v53 Would the whole hull be solid glass? how much would this boat weight? Is it a true 14' beam or a bit less? thanks for any insight.
