I have a one page product bulletin for the TAMD40A that lists propeller output at 148 with MS3B gears although I have been told by other people the 'A' and 'B' engines both put out 165 hp.

I'm not sure at this point. I do know the pre-cups on this engine are smaller than on the 'B' so I think it made less HP due to less fuel being sent to the engine.

I just installed TAMD41B engines in the boat. I still have a few small issues that I'm dealing with but it is much faster now.

Thank you for the info.
