cruising at 4000RPM produced 28.6 MPH using 11.4 GPH
cruising at 4500RPM produced 33.7 MPH using 14.2 GPH
trolling at 1800RPM produced 6.51 MPH using 3.4 GPH
and drumroll....wideopen trimmed up at 5800RPM produced 44.4 MPH using 24.5 GPH (OUCH)
and i also checked the cavitation plate running wideopen and the engine trimmed in the middle and i could see it just below the water line, so i think the engine is mounted properly..
whatca think ferm??

175 2.4L Merc Blackmax will put you right at 9gph @ 4000rpm with the same speed
