Davybouy runs a 90 Tohatsu that gives him over 40Knts top end, and great fuel consumption.
I can't remember what Nos and Matt run on theirs but I'm sure they are 70s or 90s.
I have an 80, NOS 85, MATT 90, but all nice light yamaha 2 strokes.
Yam or tohatsu 2 stroke is the best for an SR IMHO.
the 60 would be OK but not a big foot, a bit un-inspiring in the performance dept.
