Re: how & where do i find the Model S/N
Welcome to Iboats, JTS4U!<br /><br />The model number should be on a tag on the side transom clamp. It should have two numbers on it - a model number and a serial number. These are the '78 25hp model numbers:<br />258BF62<br />258BF63 <br />258B62<br />258B63 <br />258BE52<br />258BE53 <br />25802 <br />25803 <br />25832<br />25833 <br />25852 <br />25853 <br />25832C <br />25833C <br /><br />Often with OMC outboards of this vintage, the model tag is missing. There is a welsch plug - a quarter sized convex silver insert - on the engine block at the spark plug end. Into that there should also be stamped the serial number and sometimes the model number.<br /><br />Hope this help!
