Hi there! What model of motor do you have now? I had inline six mercs in mid 70 20's. One I changed to a v6 volvo and the other I replaced block with same inline 6 but added fresh water cooling. Had to rebuild engine compartment for easier maintenance on volvo and personally I felt that the early mercs were easy and less expensive on maintenance. It really depends on what you are into.... I also found both was okay on fuel with trim tabs.
