G'Day Frank,
New boat indeed!!!! (typical dealer comment there Brad!:wink: )
The conversion can be done if you're at all handy.

It is still working well on our 06 Tandem (Oasis)
After re-reading my original post I realise I never did get around to working out how to do the conversion without welding. I was looking at rivetting the tube for the new rudder directly to the older system.
If you do go ahead with it look at upgrading to the newer up/down system at the same time.
Keep us posted!
