    Default Record v-drive propeller, help with translating marking?

    Hello!
    Ihave a 16" v-drive flatty with a Record propeller o it. However, don't know the pitchof it. Does anybody have a translation sheet or equiv?
    The only stampings on the prop is "Record (one side) other side is 212,2. I meassured the dia to approx 11 inch.
    Don't really know what the 212,2 means, can't be 212,2 inch in pitch and 212,2mm would be only 8,35inch pitch, with about 0,75P/d ratio?
    Best regards

    Per, I've run Italian Cary/Record props quite successfully on two different flats. Awesome props, however a bid thin in the blade, so make sure to have it magged or dye checked for cracks (annually). I don't recall have those #'s on mine, they were just stamped w/diameter & pitch. For your application the 11" diameter is fine. What I would do is take the prop to any propellor repair service (doesn't need to be a high-perf facility) and just have them determine the pitch. Most have a small jig they drop it onto and they can tell you the pitch right away. Good luck with it! Jocko

    Hello!
    Well, seems I just need to do that, work at a propeller manufacturer for ships propellers (Rolls-Royce marin) and we do have meassuring dev for our model propellers that are about same size actually. Just affraid that it's hard time gettin the steel prop of shaft after having been there for as it seems many years (also used in hot saltwater in Florida). Aren't the Record props US made? Are they Italian?
    Anyway, thanks for helping!
    Cheers!

    If you have trouble pulling the prop......don't give up! You'll just need a good steel prop puller. Spray the front & rear with a penetrating oil (for several days if needed). Last resort would be to heat the prop while the puller is tightened. Yes the Cary is Italian, the Record is the same prop but destined for the U.S. market. This brand was (still is) used extensively on racing outboards and inboard hydroplanes. Good luck Per! Jocko

    I wanted something that wouldn't flex that is why I made a puller with a 3/4" thick backbone ! Mine hadn't been off in thirty years and it came off. Just make sure that you leave the nut on when pulling the prop so when it does come loose it doesn't hit the ground.
