Ok. I dug out the issue of WoodenBoat magazine with that info. It is the January/February, 1997 issue, should you wish to look it up. The reduction unit used in the article was a model HBW150-1.5 Hurth unit (a reduction of 1.56:1). Says here a new one would cost $1200usd, while rebuilt units are $800~$900. The reduction unit's weight is 28#. Further info is given should one require a different ratio or offset: It is suggested one obtains a T.B. Woods Sons catalog entitled 'Industrial Power Transmission Products' (717)264-7161.
On my Subaru engine (in my plane) I used a reduction drive (2.3:1) made by Karlo Kuhner of Quebec. It weighs 23#, and cost $2400cdn. 40hrs. on the unit so far and it is still smooth as can be. Best of all, it was bolt-and-go.
