    I was just perusing Merc's website and noticed there is now a new short shaft (15") 3 cylinder 4-stroke 40 at 204 lbs which would make buying Mercury an option once again for me. For a while, Tohatsu has been the only short shaft 40 option. Anybody know if this is a rebadged Tohatsu or if this is a new Merc design?

    I know some here liked the 4-cylinder 4-stroke Merc 40, but that one was never an option at 260 lbs without oil even if they had made it in a short shaft (which would never happen because it would have sunk a short transom boat).

    Hmm... comparing on websites.. perhaps it is not a rebadged Tohatsu. The 40 Tohatsu is 52.84 cu.in of displacement and the Merc 40 3 cylinder is 45.6 cu. in.
    The Merc is 2 valves per cylinder, single overhead cam (SOHC) but Tohatsu does not say what theirs is. So far the Tohatsu sounds like the stronger engine.

    I ran across some other threads mentioning this engine in the past and saying it was weak, so I am guessing it has been out for a while, but Mercury only just got around to adding it to their website?
