I always understood the Tower of Power's to be the 90, 115, 135 and 150 all with 6 cylinders. So possibly you have the HP worng or the make wrong.

When tha V6 came out in '76 they derated tha 150 in-line ta 140 in '77/'78 best I can remember. But I'm old. :redface:

Good motors when left alone and not twisted toooooooo hard. Best to leave all that to tha "Twister" type in-lines of tha day...............

Hi,

The 1978 140 was right before they left the Distributor ignition to go to the ADI system that used two switchboxes and separate coils for each cylinder. So; you want to decide which ignition system you'd rather have. They switched in mid-production in 1979 is I remember correctly.

I just had the opportunity over the weekend to view a '78 and a '79 side by side with the cowling removed. Wow! I'd forgotten how simple (comparatively) the older ones were. That big ol' distributor in there...but a LOT of open space everywhere. The newer ADI model is crammed full of wiring and electronics.

As with any old Merc like that; be prepared to re-wire internally if it's not already done. Check the wiring carefully before you even go so far as to hook a battery up.

All in-lines are very sensitive to good carburetion and cooling. Don't run one without being certain that the carbs are clean and the impeller is fresh and the cooling passages are clear.
