I am not at/with my 1987 BW 17' Montauk right now, but hope you can "generally" tell me if I am proped right? The motor is a 2003 Yamaha 90hp two stroke. SS prop (unk #s). At WOT, 5,400RPS, full trim out going 43-44 MPH. Other info: 20 gals gas under RPS, battery in console, one (1) me, 210 lbs , OK really 255 lbs on board. Sorry, no, I do not recall what mounting hole it is set at? It does snap up on plane.
Is 5,400 RPS, full trim, 43-44 MPH respectable/avg/good/OK/needs better?

Sounds fine. The Yamaha two stroke 90 has a 5000-5500 RPM range and a Montauk with 90 HP is usually good for 42-44 MPH.
