What is the size osf mercury?

I want to know what size this MERCURY BOAT MOTOR is its an inboard motor.?

• I know that you can get a book to tell you what size motors a Chevy has can you do the same with boat motor? I WOULD LIKE TO KNOW A WEB SITE THAT I CAN GO TO TO SEE IF I CAN TELL WHAT SIZE BLOCK THIS IS THE NUMBERS ARE 489777?

• Answer:

  First off, you are going to have to provide more information than this. A serial number alone won't help you. Also, did you include any letters that came before that serial number, like (A478777)? Why you might ask the serial number is not enough, well here's the reason: There is no way to narrow down the size engine of it without having the number of cylinders and the year of manufacturer. The link to one of the mercrusier serial number reference pages is: http://www.marineengine.com/mfr/mercruiser_models.html A little effort using a search engine might have have helped, I found this link in 10 seconds.
