We have the ambassador on both saildrives. The prop hub has to be machined down to accommodate it and the zincs have to be modified to fit it. The hub mod is a one-time thing, and the standard zincs can be modified with a hacksaw and a hand drill, but it is a bit of a pain. You can, of course, buy the modified zincs from Ambassador for 5x the price
of normal ones, but who can afford $100 zincs?
Our two have been trouble free for 13yrs. The only time that I know they have been put to use is when we once caught a lobster pot when sailing. After a futile attempt to get the line clear, I started the engine
, put it in gear
and the line cut like butter.
