this guy was stuck in with a bunch of other stuff i bought recently. im thinking its an Arneson, but im not sure. i honestly have no experience with these big surface drives, and im having a hard time finding info out how many teeth each arneson drive has.

the only thing i can read on it is RLCORD Nibral 24 x 29

Arnesons like Mercury had a 19T spline shaft.

What are the spline count on this prop????????

looks like 25.

Nibral is an alloy of nickel, bronze, and aluminum, " inboard propellers"

You might try contacting Pitchometer in Alameda, CA. They have been working on all kinds of props for over 35 years. Ph. 510-522-2616
Good luck.

There's a 19, 25 and 26 spline on the smaller drives. 31, 32, 33, 41 and so on

thanks for the info. looks like this guy must be for the asd8 drive then.

RLCORD is probably RECORD and was manufactured by Phil Rolla.
