1985 Mariner. 150 XR2
Bought the motor and it was turning 5800 rpm smoking and running rough.
I rebuilt the fuel pump it had a hole the size of a dime in it.
After rebuilding the fuel pump the motor is running way way better.
But running wide open I am now turning 7000-7200 rpm and it spikes up to 7500 running 55mph
the boat is a 18' Bumblebee with a 12" jackplate. 25p four blade prop.
