I have a 1992 mercury 40 HP 4 cyl power trim remote steer on a Monark 160 bass boat. I am looking into swapping the motors and going to a new Mercury 4 stroke 9.9 HP manual tilt remote steer due to most of the lakes I fish have a 10 HP limit. Would the controls work with the new motor. Will the bolt patterns be different? I have also been told that since a 9.9 is under powering my boat that I should look into a bigfoot 9.9, any truth to this?<br /> <br />With the 40 HP and two people and all gear I can run about 30 mph. Any idea on how fast I should be able to run with a 9.9?<br /> <br />Any other thoughts that come to mind before I go any further is appreciated.
