2012 excel stalker center console 18' it has a 80' beam and weight 825 lbs.The motor is a 2012 E-tec 90hp it weights 320 lbs and the ratio 2:0:1 total weight of the rig is 1245lbs with gas filled up .As of now I have a 6' jackplate (manual) I measured center on the prop shaft to the pad and from a level ground to the pad subtracted those measurements and got 5.5 ' they say i should be at 3.5' center prop shaft to bottom of the pad) scared to raise the motor higher because i dont want to pick up more R.P.M.'s as of now IM running a 13 7/8 X 19 pitch Viper S.S. prop and WOT IM turning 5950 RPM . At 46.5 MPH gps . Should I goto a 21 pitch s.s. Prop to cut my RPM closer to 5500 RPM? Or a 19 pitch with more cup?evinrude says 5200-5500 rpm max) i have 2' left of adjustment on the jackplate should i raise it those 2' and try a 21 pitch to lower my R.P.M.'s ?
