[mike-stgt]

Hi there,
next week i want to test my SR for the first time at lake garda in Italy.
I have it in the moment with a 75AET Yam, year around 1980.
Does anyone has the experience , which prop will be prefered?

Assuming it's got the same gear ratio as the 90 yams,try a 17" to start.

agree 17k will be ideal

[no excuses]

I run a 17 with a 92' 90 yam, I could runa 19 but it pulls good coming up out of the whole when loaded down with the 17
