I’m hoping to put together a Mark 25 out of components from my parts pile. Is there a way to identify the 18hp vs. 20hp powerhead?
Carburet0rs: Looks like there were two different Tillotson carbs used on the Mark 25’s. AJ47A on the 1955 18hp and AJ50A on the 56-58 2ohp. They look identical to me, except for the fuel strainer. Would either carb work on either powerhead?
no real difference in them just marketing. serial ### would tell . give us the ### and i can look it up.
Is there a serial number on the powerhead? I know it’s usually on the plate on the transom clamp but these heads are long separated from their shoulders.
