Merc trim pump

[RidgeRunner]

250 Merc EFI Outboard - Is there any way to R&R the integrated style power trim motor without removing the starbd side clamp bracket? The one allen head bolt is buried in the corner. I don't think it possible to get to but it was worth asking the experts. This is one corroded mutha. Previous owner let her sit in the drink long enough for barnacles to grow upon barnacles.
