    I like and prefer 3 blades on a mono you will find they tend to handle better with better accelartion

      Sizing and amp draw are your concerns here, for starters the CR 447's are good. Easy to sale off if you move past them. Especially if you get Chris to detounge and sharpen/balance them.

      You will be able to easily move up to 10s too at a later date with that Kv

        Oh yknow I just had a look at the pic of the back of the boat, how far up the transom off the running surface of the boat would you say the stinger prop shaft centreline is.

        I would hate to recommend a prop and have it not touch the water.

          I would start with a smaller size and then go up depending on heat from the very bottom of the v it's 1 in. from below the stingers it's 1/2 in.

            Well 1/2" should work for 447's. You may need to lower them. Did this boat run before?

            I just re read, it was not run before.

              I will start with that who is chris? on sharpening props. is my other option to go to bigger motors to run bigger props or not an option. the stuffing tubes are right on the bottom of the hull where they enter the back now sothe only way i can lower them is stinger angle i have 1/4 in. flex cables.

                        Octura has not made the 447/3 in a few years,,, you can not get them, I do have some prop shop sets of 4714/3 in ss,, that are just about the same size, or can go up to 450/3 octuras and cut them or reduce them down a bit ,,you can touch base with me threw PMs or email me at [email protected] thanks Chris

                          That should be a solid setup rad35. PropShops are good(I have a set) but you can just go Octura two blades as well. A three blade does draw more amps due to the extra blade. My preference and I'm sure Chris will agree is three blades on a single as it seems to even out the thrust.
