Thank you very much, Thataway, for this useful information. It matches my guesstimates, but it is nice to have confirmation based on experience.

Colby,

My Mercury 115 came with a Mercury 17 pitch prop, but the WOT rpm's were low. I have both the 3 blade and the 4 blade aluminum Solas 15 pitch props. They are both good. I keep the 3 blade on the boat and it gives about 5600 rpm's at WOT. The desired range on my engine is 5000-6000 rpm's at WOT.

Rob

When i had the F-115 for a decade on my 22, the right props, heavy or light, were always 18 to 19 P 3 blade SS. I tried a 4 B SS Stiletto prop, way too much.

If your going to be around a lot of ice and bulb kelps up there, definitely SS!

If I had to do it over again and had a F-115, I'd try the Solas 4B 17 P SS...

I have used the 13 1/4 x 17 aluminum prop on a yamaha 90 for 110 hours since new. In perfect water and as trimmed for speed as I can get I see 5400 at wot. I am running heavier this year so top is about 22 knots. I had a 13 1/4 x15 alum prop made for lake Powell and I think it may be my full load sea level prop. I'm looking to see 5800 wot. Will be testing for Comox cbgt. If it is a better fit I may then do a 13 1/4 x 13 for powell and higher lakes. George

Since my last msg here, I have replaced my SS prop with a 3 bladed 14 x 13 aluminum Mercury Black Max, and then stuck that one away for a spare, replacing it with a 4 bladed Solaris Rubex 13 1/4 x 13. I don't have all the technical details, but both props run WOT at about 5600-5800 rpm. (CD-22 Cruiser with Mercury 115 EFI 4-stroke). I have the SS Solaris 13 3/4 x 13 for sale now. Don't need the additional weight of Stainless, and happy with both aluminum props. Have the SS listed on Criagslist for $200. Colby

If you are going to Yellowstone Lake (7,900 feet) go with the 13" three blade prop on a 115 Yamaha motor. My motor is the Mercury EFI 115, which is really a Yamaha with Merc. cosmetics. With a medium load I can max out at 28 mph (gps speed over ground recorded), With very heavy loads, you will need to move weight forward on your 22' and use your tabs (60%) to get on plane. Changing a prop is not that big a deal if you are not on the water.

OK another 115 prop question. I have a 92 yamaha 115 2 stroke with a 13.25 x17 blade on it. I normally run it between 4000-5000 rpm for a speed range of 14 to 24 mph when loaded. a little faster when light. the sounds about right but I can drop the throttle and get 6000 rpm and 33mph loaded and even higher rpms and speed when it is just me. I am thinking I am under propped and there for looking at 13X19 to drop my WOT rpms and up my fuel economy. right no I am getting 2.5-3 mpg but that is running above 20 mph. will this work?
