Hey guys, I know this has been beaten to death but I couldnt find a answer when searching so here goes. Just bought a 25 hp Johnson seahorse (my first motor) and cant find the serial number on it. Doesnt have the plate on the mounting bracket or anywhere else. Looked for the plug on the engine and couldnt find that. This is my first motor so its a possibility that I am looking in wrong place but Ive spend a good amount of time looking and come up with nothing that looked like the pictures posted previously about the engine plug thing. I found a round thing with the numbers 4919136 on it but it didnt look much like what Ive seen online.....any help identifying my motor would be greatly appreciated. This is the round thing with the numbers on it....not sure if it is anything relevant
