Sorry I posted this message twice but it's very important for me to get an answer before I buy the engine<br /><br />I have a 3 cyl, 3 carb Mariner 75 or 90 (I'm not sure!!). <br />Inside the engine on the right hand side there is a round silver tag with tne number 9676485. I think this is the serial number.<br />There is no tag on the leg of the engine that says the year and the HP.<br />Can someone tell me with the above serial number the year and the HP of my engine.<br />Thanks
