Land & Sea torq shift propeller
 

Just found a Land & Sea torque shift propeller in my father-in-laws shed and trying to figure out what I have and what it might be worth. It has a model number stamped on it #926 and it's approximately 14-7/8" in diameter and has 15 splines which makes me think it's for a Mercury. It also has 5/32 scribed on it in a couple places as well as what looks like someone's S.S. number that was probably used as I.D. if it were stolen. It's in pretty good overall condition, the blades are NOT dinged up but do have what looks like some very minor pitting and all 3 springs are inside the hub



. I don't know what the pitch range is but thinking someone with knowledge of these might e able to steer me in the right direction by the information I've provided. Send me your thoughts.

I had years ago,keep it in the shed.

They were never a worthwhile design. Sell it for scrap value. Sorry.

we used to run those but the interchangable cams in the prop blade shaft did not last long i have on the wall here a merc shifting prop that i don,t know much about

I actually disagree with that. My father had one on his 18 ft 4.3 powered lake boat in Upstate NY that we used for wakeboarding and ripping around, and it made a pretty big difference and never had any issues with it. I think they were a good idea, when applied properly to application

Break all the time
 

A friend of mine with a prop shop thought they were cool, imported them to Sweden and sold to customers.

Got very costly since they broke all the time and you have to give a 1-year warranty by law in Sweden.

Accelerated very hard while they lasted, though.

As with most (all?) Land & Sea products, they worked much better in the catalog than on a boat.

My boat in the late 80's was one of the test boats for the prop, they were amazing and super cool the way they worked, boat jumped out of the water then shifted up to the high pitch for the speed run. I literally picked up two miles per hour over the Bravo one..

Untill it imploded..... (Everytime)

Make a propellor clock out of it and hang it in the mancave

I thought I read somewhere that somebody in California bought the patent, redesigned some of the parts to improve durability and was selling repair parts. Anybody have any knowledge of that?

So, I guess I have either a wall ornament or a clock! Any idea what the pitch range might be?

Maybe you will get lucky and it will “shift” into and out of daylight savings time for you.. worth the try!
