For Yamahas, the order (at least, mine is) is thrust washer, prop, spacer (heavy stainless splined washer), flat washer, castle nut, cotter pin.

Note: Get true stainless cotter pins from a chandler. Hardware store pins will corrode and disappear after a couple of months. It's worth the extra few cents to keep teh prop on the motor, IMO.

Pretty much any kind of waterproof grease will work; all you're trying to do is keep sea water from depositing salt in the splines between the prop and the shaft (which makes things rather difficult to remove - ask Mr. Walker.)

Cheers JKY.
I haven't heard of cutter pins before but I'm guessing they are shear pins over here?

Assembly should look something like this, the cotter pin or split pin is No. 4 in diagram.

Went to fit the prop yesterday. It was sold to me as the right prop for my engine but doesn't fit.

In keiths diagram there wasn't a Number 1 on the shaft but the back plate (?) is further back on my old prop than it is on this stainless one. So the prop sits too far back so you can't tighten the castle nut on to it as the splines on the shaft are just proud. So have I been told porkies or is there something missing?



Some photos' (taken with a camera phone so sorry for the poor detail)

If memory serves me correctly, SOLAS props fit a wide range of different manufactures engines. So you first select the correct number of splines to fit the shaft, which seems to be ok in your case as it will go on, then you get a fixing kit which includes the parts 1,2,3 & 4 to suit the engine you are putting the propeller on. You can buy the fixing kits seperatly from http://www.steeldevelopments.net/erol.html You will need the prop part No. and engine details.

Thanks Keith. Only numbers on the prop are D13 x 19 but I've contacted Steeldevelopments so hopefully will hear back.

Is that a flow-torque hub I can see on your old prop? basically these are square rubber drive type bush that the spline part fits into they act as a shock absorber... Your new stainless prop defo dont have this system.

By the way I have an as new flow torque hub to suit Merc engine and vengance prop's, see pic. PM me if anybody is intersted.

Haven't got a clue. Looks like it's part of the old prop.


Wail I wait on Steel developments to get back to me. Does anyone know of a system besides there's? Any kind of spacer?

Make sure you have the thrust washer installed (usually brass, it's a highly machined washer type thing that hits the tapered part of the prop shaft) or you risk damage to the prop shaft. It may be stuck to the old prop.

In your second pic, there appears to be a splined spacer (the last thing on the shaft as it sits in the photo.) If so, move that to the new prop.

Several companies make hardware kits for mounting props. They usually include everything back of the prop (i.e. they don't include the thrust washer.) Might be worth looking into, especially if you need the spacer (referred to in my second paragraph.) The thrust washer can be purchased separately

That's again Jky. I've just thought, I know it's hard to tell by the out of focus photo. But do you think that could be the thrust washer stuck onto my old prop? The photos' show it as very dark but I remember it to be a brass colour to the back of the old prop. Maybe what I thought was one piece is in fact, as you say. The thrust washer stuck on?
