I replaced the Hurth HBW100 transmission on an 18-hp Universal diesel I
owned a few years back. The original transmission simply refused to
engage in forward. Reverse, OK. I was told at the time that replacement
would be almost as cheap as rebuilding. Maybe, maybe not. Now, I have
another boat with an HBW100 transmission. The previous owner had
trouble with the original unit. He replaced it, and the new
transmission did not perform well. Hurth replaced that transmission
ultimately. He sold the boat to me, and now I'm having trouble with the
second new transmission, although it has very few hours. Is there a
problem with these units I don't know about? Is there another make of
transmission that would slip seamlessly into the hole left by a Hurth
transmission? BTW, for the earlier poster: Replacement isn't hard if
you can get at your unit. I think folks have already made that point.
