1969 20' engine choice

[Yamtt125]

I have been thinking about this same question for some time now, and this is what I came up with...

Alot of people here have suzuki 140's on their 20's, but the suzuki 140 is closer to a 115 b/c it used the same block.
The evinrude etec 115 i'd say would have about the same power as the suzuki 140. believe the prices of the two would be similar also.
I don't know anything about the merc opti's, but i have heard good things.
My personal engine of choice i think would be a honda 135. The 135 is based on the block of the 150 and is still only a four cylender, so your get the fuel efficiency of a smaller engine, but the power of a bigger one....

Ok..enough rambling. This is just my 2 cents.
