Chrysler Slant Six - identification???

[DianneB]

I have a 1966 Lone Star with a Chrysler Slant Six. The valve cover is marked "Chrysler 150 HP" and gives a lot of maintenance information but I can NOT find a nameplate on this engine! It is not on either side of the block, not on either end of the block, and isn't on the bell housing (in any location I can see)! The only place I haven't checked is the bottom of the oil pan!

I am assuming the engine is a 225, it is definitely marine, but I would REALLY like to have the proper model number.

Anybody know where else they might hide it????

Thanks!

It's either a Chrysler M225A or an M225D.....

And if you're quick you can get a factory manual for it....

I cant remember when the 225 was produced but I think it was later than 1966.
there was also a 170 and a 194 slant six.
but wow that goes back to many years and memory gets fuzzy.
only thing I can remember is parts are about impossible to find for chysler marine stern drives.
some volvo parts fit the drive but not many.

I thought the 60's Chrysler drives were just rebadged Volvo AQ250s.
Chrysler's own drives were more "mid 70's", no?

found this anyway, while trying to figure that out:

According to Slant Six sources, the 225 was produced from 1960 to 1976 (http://www.allpar.com/slant6.html) and was the only engine in the 'slant six' line rated near 150 HP.

The outdrive on my Lone Star isn't even "re-branded" - it is a Volvo Penta 270.

Thanks achris - I bought the manual.
