Y302 restrictor

[ricochet112]

Does the Yamato 302 use a 7/16' carb restrictor for any classes any more?

[JBM]

I believe that is the 20ssh Restrictor

[tcf284]

yes the 7/16 is for 20ss and the 9/16 is used for 25ss

I think you can use 7/16 or 9/16 in 25ssr if you change the weight of the boat.

Thanks! Looked in the rule book and inspection manual and found nothing. I just found one in an old prop box.
What do they cost now?
