I had someone tell me the octura y535 fits the Miss Budweiser the best. but don't know about the other props. Of course the boat comes with a plastic y534. I would guess it would either be size or pitch prop. Kind of like a real Prop.

There is one relatively new prop that you can try, the M-535/3. The "M" series are basically an "X" series prop with some of the tongue area removed. One local Miss Bud owner runs an X-435 on his and says that it doesn't cavitate like what the stock prop does. An X-440 would be to much prop for that boat. Here's a brief explanation of Octura prop numbers. In the X, Y or V series, the first number represents the pitch in millimeters times 1.X A 5 for instance means that the pitch is 1.5 times the diameter, the second 2 numbers in millimeters.
Y-535= 35mm dia. and 53.9mm pitch. A "/3" denotes a 3 bladed prop.

well im looking at a x-435 now and i hope to get it. how does the boat react to a 2 blade vs a 3 blade prop? ive read somewhere that the 3 has more speed but doesnt corner as easy? thanks Ron for all the help man.

I don't know as I do have some props that are available in both the 2 and 3-blade versions. Some like the X-435 only come in a 2-blade and others in only a 3-blade. One advantage ot a 3-bladed prop on a surface drive is that one blade is always in the water. I've messed around with a lot of props on my boats, one I went through at least 6 props trying to find one that the boat liked. You can find that even if another manufacturer has an almost identical size that it will make a difference on a boat. My .21 mon for instance likes a Prather 220 but an Octua M-445 is close but the boat didn't like that one. Prather props have a constant pitch whereas an Octura has a progressive pitch so it works more like a scoop. The easy way to figure this out if you don't know is to put your hand under running water with a flat hand then cup your hand to see the difference in the flow of the water.

ok i just got the x435 prop today and it said it needs sharpened and balanced? i thought the octua prop has this already done, how do i do this and not have to buy the balance machine? wich side of the blade do i sharpen, and is there a way i can check it for balance or can i just run it stock, will you notice that much if i dont do this?
