HELP, Max 1200 RPM in forward, too slow
My Atomic 4 starts rights up and in neutral will go up to 4000 RPM easily. But when I engage the transmission in forward it goes to a maximum of 1200 RPM.
I will admit the bottom of my boat, and probably my propeller too, are dirty. Which accounts for part of my boats slow speed of 1 MPH in forward. The hull speed is 6 MPH. Water temperature and oil pressure are fine.
But why will my Atomic 4 not get up to a recommended cruising RPM of 1800 RPM in forward gear?
Any thoughts would be appreciated.
Thanks,
