A gentleman, David Alan Jones, posted a link to this on Facebook. It's 436 pages of detailed info on our favorite engine: [url]http://www.packardroyal.com/4M-2500-PACKARD-MARINE-ENGINE.pdf[/url]

Must see - - - the notes on pages 84, 85 and 358 probably from an [b]old “salty“ chief, clearly an expert motormac[/b]

Great find and link Jeff, thanks much. This digital pdf is very convenient - Frankie had sent me a photocopy of his copy from his personal library, way, way, way back when I was a mere innocent infant ! ! ! ! probably back in the late 90’s.

Glad you enjoyed it Dick! Yes those notes are interesting although I think the heat from the engine he had to sit on was getting to him. [:-laughing-:]

I found this interesting, I don't remember ever seeing fork and blade type connecting rods before:

You're welcome Bill, wish I knew who to credit for scanning this in.

The site sponsoring the download, [url]http://www.packardroyal.com[/url], has some beautiful pictures of a 4M-2500 powered car which is a rolling work of art. It's a beast about 3/8 the length of a PT boat.
