The
Ocean 48ST looks to be the closest direct replacement for size and power ratio. That said, the
EVO 45 and
Ocean 46 would also be reasonable alternatives. Both the EVO 45 and Ocean 46 have a slightly smaller base diameter, while the Ocean 48 is slightly larger than the existing winch.
If I remember correctly, the gelcoat beneath our current winch is less faded than the surrounding area, so moving to a slightly larger base would actually be beneficial from an appearance standpoint. Looking through a few photos of the existing installation, it also appears there would be plenty of clearance to accommodate the larger winch without any space issues.
Older pic, but we haven't moved the winch, so it still applies.
