Changed my fuel pump and found a surprise

Post by jtalberts »

So I could never find a service tag on the bell housing for my engines. I knew they looked different from the 318s that were in my 71 boat and all my friend's boats but I figured they were just a newer version. Hell, the surveyor and PO said they were 318s. So anyways, the PO broke the mechanical fuel pump outlet when putting on a new fuel line this past year and it was shooting gas all over the bilge when running. When undoing the bolts I found a tag hanging on the engine. I wiped on the grease and apparently I have twin Chrysler LM340s. So my boat seems like it is a very rare combination.

And quick, too! Those 340s were rockets.

I could have sworn I had my Sig all set up prior and now it is gone. I put it back in there.

340's are hot motors. A friend of mine had one in a Challenger and it flew!
