Anyone got views or experience to compare advantages/disadvantages 2 or 4 stroke out board engines?
My contribution is based on comments from my brother, whom is an inland, freshwater, avid sporting fisherman with experiance on very large and very small, lakes and rivers, since 1970. Since the early 1980's he was a part time commercial fishing guide to sportsmen. Since the early 1990's his primary occupation has been a commercial fishing guide on large (**) freshwater lakes and rivers, in the Midwest US and Canada. ** Large lakes means the shoreline may be not visible and large rivers means with large commercial vessels.
Posting his web site may add creditability, but it may breach this boards guidelines of remaining non-commercial. In short, just trust me, in that I am relating my brothers' vast experiances with 2 and 4 cycle outboards.
Although he has multiple methods of propulsion on each boat, large outboards 150+ HP or twin 50-75+ HP, and electric trolling motors - bow and stern at the same time; he also has small 5-10 HP gas outboards as trolling motors for fast river conditions.
His comments and my observations:
* He has not owned a 2 cycle since the 4 cycle technology improved vastly; about mid-1990's, as I recall.
* He said (about 4 cycle) clean, efficent, reliable, no mixing gas and oil, can use one fuel and multiple fuel tankns for multiple engines - everything is interchangeable.
* Longer engine life, less noise and air pollution
* No fuss, no muss. Simplifies life greatly.
I have no idea how engine warranties, weight, fuel consumption, or purchase price compares today, but think it is worth considering those factors.
Just trust me at face value, but also consider the other posts, your own reseach and apply that to your situation.
