Both have carburetors. I would rather have the low hour- 190 hrs engine.
The high hour engines like CaptMac, are in good shape because they are probably run at least several times a week, if not every day in charter service.
When you are buying a used engine, you don't really know how it was cared for. If only in fresh water--and documented--that is a plus.
Salt water--was it really flushed each time? A friend of mine bought a Honda was told it was flushed each time--had low 800's hours--and the cooling system was destroyed by corrosions--he had to buy a new engine.
Has the engine oil been changed each year, even thought there were only 20 hours use each year? If the engine was not used for a few years, was it properly fogged, and the oil / gear lube changed just before the storage?
