In 1979, Testors introduced a one-time-only 1/25 scale replica of the 1977 Miss Budweiser unlimited hydroplane (No. 4179). It included a simplified Merlin V12 engine and automotive-style vinyl adhesive panels for the top deck graphics. Monogram introduced two combo kits in 1990 with slightly different iterations of USFORA “Formula 1” 3.0L outboards. The Mach I (No. 7240) and Yamaha boats (No. 7241) were somewhat simplified replicas without engine internals, while the trailers could be adapted to transport other relatively larger 1/25 scale watercraft.
