I have a Skat Trac stainless impeller it has five blades and a 10-20 pitch. I am trying to figure out if it fits a omc turbojet. Any info would be much appreciated. The number of splines and drive shaft diameter would help as well.

Made of stainless steel, labeled 10-20, 18 splines with a space between the nose of the impeller and the spline for a seal, threaded on the opposite side of the impeller from the spline to attach to the bolt that runs through the bearings, 5 blades. The impeller is roughly 6-1/2" in overall diameter. The spline is inset 0.73" from the nose of the impeller, the bore of the space in front of the spline is 1.10" to hold a seal. Cannot measure the splined shaft diameter as the boat is in the dark at the moment. (I just happen to have a spare impeller housing with an impeller in the garage to measure).
What else did you want to know?

Thank for your help you confirmed my suspicions. I have a new in the box Skat Trak impeller for a Omc Turbojet. I sent it in to Skat Trak to be identified but they were no help. I even paid them to identify and recondition another impeller at the same time. Asked for that one to be positively identified. They sent them back to me. All I got was that the reconditioned one fit a Yamaha. They were supposed to put what models and year on the box. That is why I paid them to recondition it. I was not looking for a freebie. So after five hours of research on the web I have at least identified something. I invested $80.00 with Skat Trak. They were the ones who suggested I send them in. I know they have great products. But were not much help to me. I am just trying to finance my toys Waverunner, Motorcycle and Snowmobile. Your measurements were right on again thank you very much.

What is "a 10-20 pitch" on the impeller? It sounds like it has two pitches simultaneously. Can you explain? Thanks.

Jim: I suppose the 10-20 designates the pitch or angle of the blades when they are close to the hub and then at the tips. Jet impellers are rated this way. If you go to Skat Trak or Solas websites and look at applications. You will see that impellers are listed this way. I just want to say that I have been on alot of forums and you guys are very helpful.

I was not aware that Scat-Trac or anyone else ever offered any "modified" impellers for the OMC Turbojet. After my initial response to yur inquiry, I dug all over their website, and never found ANY mention of any products for OMC jet drives.
From the looks of my "spare" impeller assembly, I could use to send them my spare impeller to be reconditioned. The leading edges of the blades are dinged.
In a similar quandry as Jimh, I spent some time on Scat Trac's website before I understood what 10-20 meant, and why my two impellers are clearly stamped with this on their noses.
Now that you have identified the impeller, do you have a boat to run it on?
