RE: SAW SV
if you really want a 540 size motor go to hacker. order a 5XL, get the hi temp magnets and throw on some boca berings
run the boat for about 20 seconds and see how it goes.
the boat if ran SAW is a P mono which i believe is up around 70 mph.
you SV 27 hull would be stupid at anything over 50.
get a diffrent hull
