[Public-List] Stern tube

[Kris Coward]

What do you mean "without removing the engine"? If the job's done by
hauling, the bearing housing's going to come off and go back on again,
so the engine's going to need to be realigned anyway.

Of course hauling the boat provides more opportunity to clean the
bottom, touch up the bottom paint, etc. than pulling the engine (and the
stern tube rebedding/resealing is easier on the hard) -- but you don't
need as big a crane to pull the engine :)

(I write this all as I'm years overdue to haul and repaint the bottom,
but don't know how much it's worth looking for a yard that isn't booked
solid with slower, socially-distanced launches now that we're allowed to
launch boats in Ontario again. Of course, if I hadn't repowered to
electric, there'd be plenty of available cranes to pull the engine with
-- but as things stand I can just lift the motor out with my bare
hands.)
