I saw the admirals post on the blowout prop sale at iboats. problem is that i do not know size? the boat is a 1989 hydrasports 3500 lbs dry, 5500 lbs loaded, 24 degree deadrise, 8' beam i am in process of repowering with 2003 counter 175 johnsons. the older motors were 200 suzukis running 14 1/2 x 20 props. have no idea of old engines rpm range. does anyone have a similar setup to give me a guide on propping?. a was thinking of the 14 1/4 x 21 or the 14 1/2 x 19 ballistic prop.
