washers behind prop

[O2VW1.8T]

How many washers should there be behind the prop. I just removed my Skat 13/17 and it had 2. I'm going to try a stock 08 prop do I leave both those washers in there...

I only have one but do not know if that is the correct answer but that's what I have.

Yeah I'm going to try one also and report back on how it runs .

the washers are optional. i personally like the washer behind my 12/17 because it loosens it up a tad on the bottom. without the washer it just dart wherever the ski is pointed. this is in a mag pump.

wow just looked at the pic and man those are some big spacers. mine is a lot thinner, maybe 3mm at most. my prop is a cut back so the washer allows me to go back and forth from cut back to non cut back.

they are 5mm thick the first one installed sits about 1-1.5mm up from the surface... Im hoping this clears up my bottom end.

Hmmm... I do not have any washers at all.

Is that bad?

It just determines how far the impeller is from the vanes. You can adjust "cutback" that way.
On my 140 Mag, a spacer is actually necessary because the impeller that was ordered new from Skat Trak was so far cut back that the hub would rub the stator section without a washer.

no, you probably dont need one.

My 140 is exactly the same - I need 3mm of washer just to allow the prop to clear the static vanes

-3mm with no washers here.....the ski hooks up like mad and it is point and shoot like Tzane says..

Hmmm maybe I will remove the washer and see what happens

does yalls literally rub the stator section without the washer? mine is very very close, cant even get my fingernail in it. just curious, i need to put the washer back in mine, i like it with it better but had to try it without just to see what its like.

if you remove the washer/washers just make sure the prop and driveshaft spin before you reinstall! last time I messed with washers I removed, reassembled FULLY then hit the button and it was locked tight lol... make a 20 minute project like 2.5 hours
