The rating listed on the jet motors from everyone is the brake horsepower
not the true jet hp, for that you add 20%, or subtract 20% if you want the
real work horsepower. Up here in the Pacific Northwest we are having some
trouble getting jets for larger boats, it seems some dumb ass had a 200 hp
tiller jet and ran it hard enough aground to kill himself, so Yamaha and
Mercury (share the same power heads) decided to stop somewhere in the 40 -
50 hp range and we're waiting for the shoe to drop on the other
manufacturers.
