My boat is a 260 Sundancer - according to the owners manual it is 6,200 lbs but I weighed it and it was closer to 7,000. That was with full fuel (84 gal.)and water tanks (28 gal.) It also does not have a generator.
I apologize for the delay , just got back out today. So here it is-Prop #s48-823661 L- 20PMercury Marine48-823662L - 20PStainless steelWOT - ( today) 42 MPH @ 5,200 rpm Also - 31 MPH @ 4,200 rpmand 23 MPH @ 3,500 rpm
I had my 260 with 6.2 mpi out yesterday, calm day and got it to 44 mph. I’ve only had it for one year now so I can’t tell you yet what pitch my props are . I can read the.numbers if it helps.
