Thunderboat Boat Isolator Block
Rule change proposal:
In the Thunderboat class ;The stock plastic isolator block and
gaskets may be replaced by one's made of a different material as
long as the overall thickness, (block plus gaskets), size and shape

(a) GX-1 will include engines from 15 to
31.99 cubic centimeters.
(b) GX-2 will include engines from 26 to
35.99 cubic centimeters.
