Default Mercruiser serial numbers
Looked at a boat today in the rain, dead batteries , couldnt open hatch. Guy says they are 370 HP and he gave me these numbers
B405478
B404479
Boats an 87 and he says they are the original motors.. trs drives.
They kind of sound like gm casting numbers except for the B
Anyone have any ideas ? Thanks
