Hi Julian,

Just in case, for a 1982 with original engine, it should be a Universal 5424, 24hp, with a Hurth HBW 100 transmission 1.8:1 on a 1 inch shaft. The prop should be right handed. The specs said that the transmission ratio is 2:1, but they are really 1.8. If not mistaken, the exact ratio is 1.79:1

Hope this helps,

Some time ago I saw some correspondence on the listserve about feathering propellers - right now I have a folding prop which I would like to pension off.  I would appreciate any thoughts any recommendations people have.  I talked to one supplier, who told me that before recommending anything he needs to know a) the engine model number, b) the transmission ratio, and c) the shaft diameter.  My boat is a 1982 with a 25 hp Universal which I think is the original.  Since I am about 4 ½ hours away from my boat right now (which is in Mackinaw City MI) I would appreciate any information.
