Dix 43 stern gear and A bracket

I have never been in favour of whats named a P bracket at the position just in front of the propellor,at best they leak,worst,they come loose,so when I was faced with how to position a bearing at the back end of this prop shaft,making an A bracket was the solution,its been a 100% success,the bearing inside the front and rear  tubes is made from Vesconite,which is a South African invention,made in Durban I believe.


An 18" Max Prop Classic (thank you Notty) which works really well,forwards or reverse,the engine is the Perkins 4108 46hp diesel and the pitch on the Max Prop is set at 18 degrees,which is about 2 degrees to course but the engine and  boat seems quite happy at this,with a cruising engine speed around 2000 rpm.
Note the two shaft annodes,made from real Zinc and not Alloy,Zinc costs more but lasts longer,as do two annodes over just the one.

The 35mm 316 stainless steel shaft if well supported each end and a dripless seal if fitted inside the boat,its a great idea and never drips a drop.The paint is International Paints Prop O Drev,applied with a spray can on their special etch primer,also a spray can application,recomended!
