Depending on your drive system there can be clutches involved. Just about
all inboard + lots of i/o drives except for merc alphas have some sort of
clutch system to engage forward and reverse. There are also rubber
couplings that can exhibit the same behavior when they have slipped. What
is between your 454's and the props?

I think they are alphas, I will go to the marina in a couple of days and
check.
