My new (to me) '95 SuperJet came with a Solas YB-SC-A prop. Anyone know what pitch this is? I've tried searching. I even emailed Solas.

Got an email back from Solas - its a 12/17 pitch. Seems to work okay on my ski (stock 701 w/ Factory Pipe and water box). I haven't ever ridden another SuperJet so I don't really have a good baseline to compare to, though.

I have one of those too. Does yours have a big bullet shaped hub?

You got a grinder? Flatten those beat leading edges, then angle back the backside of the blade edge at a 45*. Piece of cake!

I have an angle grinder... I really need to get a bench grinder haha. Thanks that sounds doable, I guess I just read impros repair process and got intimidated.

Angle grinder is all u need. I dress them up all summer long with a 4" angle grinder and thin cutoff wheel. Leather gloves, and keep your digits away! I still have a black mark on my left middle finger where a cutoff went through the glove and maybe 3/16" into the end of my finger....right through the nail too. Hurt like a sumb!tch.
I probably have a screwed impeller around I can make a short vid if u want.

Ouch! I bet that did really hurt.. and take a while to heal up if it went through the nail.
Thanks for offering to make a video, I appreciate it. I think I about got it. You are right easy peasy with a cutoff wheel. The tool for my Solas YQ big hub does not work so i need to get a different removal tool to get to these so I can hammer them smooth.

I file mine by hand. I want to remove the least amount of material as possible. I finish with sandpaper. You can also print a pitch guage to check your blades. Usually it's the trailing edge of a blade that gets bent. If you need to straghten a blade I hold it with a vise and bend the blade with a large adjustable wrench tightened onto the blade.

I remember seeing one on here previously but cannot find it now. I just want to print one off on paper to get an idea of where my impellers are at. Anyone have a link or a file?

Like Mark said if you have a vise and an adjustable wrench you can repair a lot of stuff, a grinder with a cutoff blade and a flap disc comes in handy as well, , you will also need some kind of flat table and a set of calipers to measure the blades with, barring that you can use a piece of cardboard bent at 90 degrees and mark one unbent blade as a reference then set the other two blades to the same height.
I got a good look at the tools professional prop benders use and plan on building some of my own, they are basically just two pieces of steel rod welded to a piece of flat bar with a gap between the bars for the blade to go in, pretty simple but it allows you to get into a much tighter area on the impeller to get the waviness out of the blades easier.
As long as the blades are just bent and not torn you should be good.

I thought the angle grinder with a cutoff wheel worked really well for grinding the blade flat due to its size. I think I will probably use a file to give it the 45 degree angle like Myself mentioned. Using sandpaper at the end seems like a nice touch. Thanks for the link to the printable pitch gauge, I had not seen that thread before. I saved the PDF posted for printing.
Thanks for the tips! Prop repair and bending is all new to me. ill try and get the bend blades all to the same height.
It would be cool to see those tools if you ever build some of your own!
I use a vise with aluminum blocks on its grips, and clamp the top and bottom of the impeller. Then I use a brass hammer and measure progress with a machinist scale. Most 144 impellers you come across have too much load for best response. Hammering on the leading and trailing edges can make a huge difference in performance. The typical 62T cylinder will really come to life if the distance between the trailing edge and the blade above is 1.3 inches. A nozzle bored to 85MM also helps noticeably. This is something that should be generally well known but its not..
