2 stroke(optimax) vs 4 stroke

[Lake Chuck Duck]

Its another one of these threads guys.

I am starting to dig on the market for a used center console bay boat. I have been pretty set on the idea of getting a four stroke due to gas mailage, and the fact I have personal experience with yamaha and suzuki 4 strokes with no complaints.

Well I hit a snag. I found a boat that I will be looking at today that I really like so far. It is a 06 Kenner 1800 and it has (assuming 06) Mercury Optimax 115Hp on it.

Do yall have any reccomendations or advice here? Perhaps anyone that has switched from one to the other? What have yall heard good or bad about the 06 era Merc Optimax? Hold up in saltwater?Gas mileage?

Should I stick with getting a Yama or Zuki four stroke? Thanks.
