After 13 years in my Sabre with an XR6, I’ve decided to upgrade to a Puma, Eyra, or Cougar. I’m looking at boats 7 years old or less. Except for the rare boat with a SHO, just about everything 18 or older has an Optimax. Am I better off buying a 19 or newer with a 4S? I hate the idea of making payments on something that has a higher chance of failure. From the research I’ve done and people I’ve talked to, the Merc 4S powerhead has been flawless. I can afford a 4S, but you know how it goes, the less money I spend to get what I want, the better.
