I am considering repowering my Boston Whaler. I am weighing the pros and cons. 4 stroke is cleaner burning, more dependable than what I have , but heavier and I understand higher maintenance. Plus i do beleive quite expensive. My existing 88 hp Evinrude is probably 30 years old, it slow starts, smokes at start up (significantly). Dies when at idle for any length of time and then some times extraordinarily hard to restart. I t does not have hydraulic tilt, mixing fuel is a pain, but it paid for so. So if you were me what would you do? If I were to repower 3 rivers the place to go? Thanks for ideas.
