I have a problem on my Lagoon 400
that has me and my engineer
It has been out of the water
for antifouling. I changed the oil
in the sail drives (yanmar SD50s) and the engineer
changed the sail drive zincs (requiring removal
of the propellers). The props are folding 3 blades - flexofold I think but not sure what brand Lagoon
supply. When the boat went back in the water
after reversing a few yards I immediately lost
all drive - first in one engine
then the other. I think this happened when i went from reverse to fwd.
I assume the cause must be incorrect installation
of the props but the engineer insists this is not possible and he has fitted many before. There does not appear to be any problem with the sail drives.
Any suggestions/experience of this issue? Are there any common mistakes
when refitting folding props on sail drives that could cause this?
