I have a problem on my
Lagoon 400 that has me and my
engineer stumped.
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?
Thanks
