Way OT - Evinrude motor on a house boat

Does anyone know where I can go (on the web or elsewhere) to find out more about the motor? I have the s/n and model number but don't know how to interpret them.

The boat is a '72 and I'm thinking the motor is probably about the same age.

This whole mess is gonna get sold as soon as I can find out enough about it to talk about it intelligently to potential buyers.

Thanks!

Does it look like thes?

when OMC was still alive, Johnson was white paint and Evinrude was blue, other than that they were practically the same engine

OMC fell on hard times and the remnants were bot by Bombardier, according to my boat dealer he can still get parts for my OMC engine

if it starts and runs you are doing good, if it charges the battery you are even better, about time your engine was built, the motors were built for power, mid-70's on they dialed them in for lot better fuel consumption

lets hear some other opinions

Really good discussion board too for outboard ailments.
