Not an AT10 – I’ve had one. The AT10 is a 5hp with a common 5hp block. This motor has a different power head – similar to the power head on a DT38 which I used to own. This power block has no head bolts as does the 5hp block used for so many years. That’s why I suspect this motor is a 4.2 hp. I have an old Johnson service manual that has a rear photo of a LT38 but with the addition of a recoil, and thought this motor might be that. But I have not been able to find a model number and serial number on it anywhere. Had the same problem with the DT38, but found the model# and serial number on the cast cover. I’m new to old outboards and thought perhaps someone with more knowledge than me (wouldn’t take much) might know where that model number and serial number might be found. Sure appreciate all the responses and hope we can get this pinned down.
