Well, if these are my two choices then I would say it's an M-18 because the engine in the picture, like an M-18, is fresh water cooled whereas a 5411 is raw water cooled. I had an M-18 in a 27 footer I used to own and it looks like what I see in the picture.Does anyone know which Universal motor this is? Suspected M-18. Or is it a M-5411? 1984 Ericson 30+.
Thanks,
Doug
Until someone can answer this more definitively, back when I was considering an E30+ I did notice several of them that were fitted with M-18's.Thanks Alan. Does anyone know what the stock engine was on the E30+? Were there different options? The M15 and the M18 look similar to me in the very few photos I can find on the web. The 5411 does look different.
Thanks
