I am considering repowering my Montauk 17 with a 1997 Force 75. The boat is used only in salt water. The motor I have now is a very tired '84 evinrude 90 v4. The Force 75 is a 97 with few hours. I know nothing about this outboard and I'm looking for advice about this motor. Is it reliable, can I buy parts for it? What is a common weak point in this motor? Any advise, insight and recommendations would be appreciated.
