1995 Mercury 75 hp. 17ft.Ranger Alum. bass boat.
I don't know how to set the timing and don't have a manual for the motor.
The motor seem to runs good and hitting on all 3 cyl, The linkage/throttle is advanced as far as it can go.
Yet the most it gets is 4100 rpm's and 30mph. at wide open and trimmed up.
The load is minimal and no soaked foam.
The prop was changed 6 mo. ago and then it would run 5200 rpm's at wide open and 45
mph.
Checked the timing and it's 12d at idle.(like I said I don't know the specifications for this motor)
??? the owner said it slowly lost rpm's and slowed down to the present speed.??
ANY ideas on why it would slow down??
My first thought was the flotation was water logged but it's not.
My second is the prop 18p.SS was the problem as he said it was changed.
ANY thoughts??? THANKS!!!
