Pitch my prop for year round or have 2?
I curently have a Solas 13/19R and in the dead summer I turn 8120 RPM with one top run of 74.2, but consistantly at 73.6 no matter what the conditions are, seats and bucket in or out.
Now with 59 degree water I am turning 8180 -8200 RPM still at 73.6 MPH so it seems I have exceeded the 13/19 impeller so I was thinking of having two props, one for summer and one for winter.
Should I have two props or should I have mine tweaked to try and be a year round prop? I was thinking to get a 15/20, but dont know if that is the right solution. My holeshot and top speeds are killer and I dont want to lose either.

I would try the 14/19 befor the 15/20. I think the 15/20 may be to steep for an RXT

I would get another prop for this time of year so that you dont have to repitch again for summer.
I would buy a 4 blade and pitch to a 14/22 for starters and i bet you will gain speed.
what is your boost right now.
I ran a 13/23 pro pitch in my T-X last week with 83 ring and was awesome but was on limiter. speed was 73+. will be a good prop for me in summer.
this past weekend i ran a 15/22 that actually mesured out to a 14.5/22 and was 8,080 rpm running best of 74.6 mph.
I just thought i would share some info.

Gus, remember that we dont have a very effective winter... We will be 80 degrees most of it....

Go with another prop as your already running 82 ring.
You can never have too many props.

I would add about 1mm pitch to the prop and run an 83mm ring in the summer and an 81mm in the winter.

I would try to be pitched to were you can run the smaller(81mm) ring in the cold temps and change to the larger rings (83mm+) in the heat.
Or you can do like Steven and stock pile every prop that is for sale in the classifieds so that no one else can get there hands on them.

Thanks for the input. With my RPM in the summer still being a tad over the sweet spot of 8080-8100 at 8120 I have the ability to have my current prop tweaked a little to bring me down 60 RPM and just run one prop year round putting me at 8060 in the summer and 8120 in the winter. I shouldnt even have to mess with the rings either. Saves me some $$ too and I wont hear the wife yelling at me cause I bought more jetski stuff.
