[charlie_the_tuna]

hey guys, my buddy has a 95 or 96 v21 with a 96 johnson ocean runner.
he says that he tops out at 4400 rpm. this does not sound right to me.
also says he thinks hes getting less than 35 mph.
says that hes buning a sh!tload of gas.
running out at about 4000 rpm.


WHAT GIVES?

what does he need to do?

being an I/O guy, the only thing i can think is he is an impropper propper.
any help will be passed along to him.
