[Rhodes22-list] Converting Electric Winch Motor Lift to a Manual System

[Tom Van Heule]

I don't disagree with the sentiment.
If a 6:1 did fine why is a 9:1 having issues?  Is it a law of finishing
returns adding blocks, while also adding length load and a second or fourth
set of block friction.

The outboard isn't THAT much heavier to cause a 49lb effort.... I have the
Merc 8hp 4 stroke. 90lbs wet....

Seems like maybe something isn't aligned ?

Fwiw, my electric lift works well (2011 boat recycled 2017) although a
teeny bit jerky, I don't fear for it past hooking up a safety chain to it.
 But maybe working the lift in larger waves has an effect on the
experience.  It's usually calm at stern when I drop the shaft down in the
water/prep for approach to launch/mooring.

But we all enjoy!!!
