U-35 Stalls when shifting into reverse??

[Nico Walsh]

The Universal 35 on Far and Away has just taken to stalling when put in reverse . . . Fun! 

I thought maybe the coupling had slipped and the prop was hitting the rudder (who I would surely have felt), but observation of the shaft while shifting suggests that is not occurring. The stall is immediate, seemingly before the engine even takes a load. Any ideas??

sounds like a neutral safety switch/low oil/kill short...do you have such a one on there?

Hansen Marine asked "Do you have a Maxprop?" I said I do, and he suggested the pitch-setting device on the prop had sheared so it went to full pitch in reverse, stalling the engine. I'll haul soon and see if that's the case.

Mystery solved: I changed the zinc in August using SCUBA. I used the wrong zinc, and it interfered with the ability of the Maxprop blades to fully flip. 

Always something . .. .

Wow... Thanks Nico for following up with the resolution. From where do you source your MaxProp zincs?

I typically get them from a local yard. The thing is the boat is new to me, and the boatyard that winterized her last year gave me the spec. I should have noticed the issue but I did the work underwater and was not sufficiently careful. The zinc went on fine . . . .

Could have been a lot worse. I discovered the issue when I backed away from a mooring, not when coming alongside a pier.
