Hello, I just purchased a pontoon boat knowing that the power tilt and trim motor was dead. Referencing the Mercury parts exploded diagrams on the internet for a 2001 60 hp 2 cycle Mercury Bigfoot indicates that the replacement part is 893907A02. The only issue I have with this $500 replacement part is that if I search ebay and the internet, a very similar mercury power tilt and trim motor (809885A2) is available for $180. My question is this...Are these possibly interchangeable? The $300 savings is attractive. I wouldn't want to go through a custom retrofit but thought others might have been down this road before with a succesful swap. Cost differential would surely allow for some risk as well. Should I entertain the thought of this or just bite the bullet and shell out the $500? Or, are there other used/remanufactured suppliers that I haven't found in my search. I've included an attachment that shows both trim motors. They look like identical exploded diagrams, but sure know that this might not result in everything being the same size. They look so close that I thought it was worth asking. Your opinions appreciated.
