I just bought an older boat with 1980's vintage Lewmar
48 3-speed primary winches. The winches are functional, though they definitely need cleaning
and servicing. Upgrading to self trailers is high on my priority list. Are the 48ST's and the old 48 3-speed winches similarly sized, and a direct replacement? I'd prefer to reuse the old bolt holes, for obvious reasons.
I also have Lewmar
16's on the mast
for the halyards - are the 16ST's also a straight replacement?
Any advice on this upgrade would be most welcome.
