"David, forty plus years as a mechanic, and twenty plus years working on these drives says that I am. I've helped many people with this very same question..... and many times.
However, it is easy to see how this can be confusing.
<font color=""ff0000"">NOTE before we go any further....
What the chart is calling a "thrust washer", is commonly known here in the US as a "spacer/line cutter".
What some call a cone nut, is actually a "spinner".
There is a one piecc spinner.... and a two piece spinner.</font>
The chart above should really read;
<font color=""0000ff"">Volvo Standard shaft = 200/250/270/275 shown w/o short spacer/line cutter.
Volvo Long shaft = 280/285/290 shown w/o long spacer/line cutter.
Net shaft spline area is same when the appropriate spacer/line cutter is used on either shaft!</font>
**Look closely at both shafts. Yes, you will see that each grosses a different length. 280 being longer than a 270.
**Now look closely at both types of spacer/line cutters. (you will see a difference in length...... short on 250/270/275.... long on 280/285/290)
**Now consider the NET length of each shaft once the appropriate spacer is used on the shaft. (remember; short on 250/270/275.... long on 280/285/290)
**Now look at the recess within a long hub prop splines when installed on either shaft with the correct spacer/line cutter installed. You will see that the aft most part of the 2 pc spinner will protrude into this..... thus giving you the thread contact necessary.
**Now notice when a short hub propeller is installed, that the full spinner (or both pcs of the 2 pc spinner) works just fine.
**Also note that each type of prop-shaft bearing carrier... (AND ring anode).... are different. The result of this is a part of the mix regarding the required spacer/line cutter for each drive style.
Trust me.... It is not the shaft that determines which hub prop you can use.... not unless you have figured out a way to omit the spacer/line cutter.... and that cannot be done.
It is the hub style that determines which spinner style to use!
