My 88 Wellcraft 3.7 engine coupling blew this weekend. My buddy has the same boat and his blew last month. On his we could tell that the wood brace 4 the engine mount had saged over the years but mine seems fine. Now i know with a 20yr boat anything can happen but we both purchased these boats last year and are wondering if engine couplings are prone to go on these engines? Or mabie its the set up? Is there somthiong we should be aware of?
