Try a dealer for an owners manual (nothing on line at least that I know of), for a workshop manual the official manuals are much better than non official ones. CDs off ebay are often crap.

Wills Marine have been found to be good for mail order spares .

The i Boats forums are the place for help and advice when this forum fails.

Parts lists and exploded diagrams HERE
 
Specifically for that model or a Seloc or Clymer manual covering a wide range of models produced over quite a number of years?
 
Diagram of the lower unit HERE

The centre part of the hub #37 is pinned to the shaft #32 with pin #38 Then the rubber part #35 fits on that followed by the prop which is retained by split pin #36 This pin is offset and locates in a groove in the end of the shaft.

The idea is that that if the prop hits and obstruction it will allow the shaft to spin, the prop slipping on the rubber splines.

Important that you always use the correct size of split pin to retain the prop and fit a new one whenever you refit the prop. Improvise by using an old pin or one that is the wrong diameter then the prop falls off. Seen it happen!

Amazon.co.uk for Amazon in the UK but be warned the Seloc and Clymer workshop manuals cover a wide range of models over a fair number of years (Up to 60hp and from 1971-89 in the case of the Seloc one) Consequently they do not cover any one model in full detail.

You would be well advised to get the Owners manual from a dealer in the first instance as that covers operation and routine maintenance

Fuel Mix by the way is 50:1 (Even if the engine decals says 100:1) using a TCW-3 spec outboard engine oil.
