PROP speed and compatibility

[SHOTGUN RUSS]

Hi, I have a spare prop for a AQ260/290 with a pt# C 851138. This prop looks like it is for a newer leg, will it work on the 290? One other really weird question: does anyone know the Boat speed at idle on a 15"x19" prop for the above? Thanks for any info!

That prop is a 14"dia x 21" pitch left hand rotation long hub high speed aluminum propeller. Volvo renumbered their parts system, can't remember when, but that 851138 is the old part#, superceced by part# 854979. It fits any 200 thru 290 single prop drive.

Theoretical speed at 650 rpm with 1.6 ratio drive and 2% slip is about 8mph using a prop calculator.

Thanks, I was hoping the spare would work.
