LOL, Ok. Here's my top picks....It means nothing other than the fact that I have made friends with them all, approve of the design and never have to scratch my head wondering "WTF?", never feel compelled to throw things, and never have to study all night long just to make 40 bucks swapping out a sensor.
Here we go;
9.5hp and under.... mid 80's to 1998 Yamaha
9.9-15hp... 1981 to 1992 J/E
20-35hp... 1981 to 2005 J/E
40hp... 1984 to 2005 J/E
45hp... 1986 to 1989 Merc (classic)
50hp... 1981 to 2005 J/E
70hp... 1984 to 2008 Yamaha
75hp... 2004 to 2007 Evin E-Tec
85hp... 1979 to 1995 J/E
90-115hp... 1995 to 2006 J/E (60° V4 eagle series)
150-175hp... 1991 to 2006 Evin (60° V6 eagle)
200hp... 1991 and up Merc 2.5 liter EFI
I have yet to see a 4-Stroke in any hp range that I wanted to own. IMO the only good thing about a 4S outboard is that when they do run well they are quiet....that's it, everything else about them just sucks and they are a PIA to work on.
