The original motor from the factory was a 3 liter 200 hp pro XS equipped with sea star hydraulic steering . Everything seems to line up to the older motor with the steering cylinder and swivel . Sea star says their HC 5345-3 model fits the 2.5 liter Mercury . Basscat installed a HC 5345 10.3 Sea Star at the factory . Is this model compatible with an older 2.5 Merc or could their be binding or other issues?
