I am running a Renegade 4 blade 25p I think its 13.5 inch.. Runs about 5800 RPM.... I also have a Raker 2 3 blade that my 225 has trouble turning and I get about 5000-5400RPM
Can I adjust the jackplate up or down to maybe make the Raker a little easier on the engine and potentially pick up some speed too?
