:cheers IF IT FLOATS,,,,,,,,,,IT`S A BOAT :cheers

so you are saying theres no diff to the motors? some said i could have a 62 409 boat motor because theres no casting codes anywhere on this motor on a build by the oil filler J/2/2 nothing by the rear bellhousing no codes..and very strange motor also the motor has NO X on it

[jim_ss409]

Apparently most boats got truck engines but it sounds like you've got a strange one there. 62 car 409's had no X but I don't know about the truck blocks. Did you look at the heads to see if they are high performance models. All 409 blocks and cranks are similar it's the other stuff that sets them apart like heads, intake etc.

this motor has 690 heads, factory 3814881 intake but it don't have a 409 crank in it looks like its a stroker strange motor..and no casting nos

I'd imagine that the starters would be pretty much the same. The boat version may have some extra "sealing" to prevent moisture from getting in.

As for the engines;) , it's my understanding that the regular production boat engine is essentially a truck engine. A good workhorse, but not very powerful.

[Daves 62/409]

i don't think its a boat motor i thought because that because no casting nos anywhere on the motor its also a full roller motor.the guy that did the machine work is dead now but all he did was drag motors for cars,in ILL he was a old racer and builder of drag and stock cars.his name was.Jack.Waldvogel live in Joliet ILL.

OK... I give up.... is there an ENGINE amongst all these motors ?:confused: ;) :p

[bobs409]

Ah yes, a motor is an electrical device and an engine is...well, it's under the hood of a car. Right Aubrey???

Anyway, here's some specs of a '62 marine 409. Someone gave me this but with my terrible memory, I forget who or where I got it from.

[Daves 62/409]

thanks but i don't think its a boat motor no its not in a car yet it came with a 1962 impala SS 409 car its a new fresh motor never installed have pics if anyone wants to see this motor i showed it to some guys here that have 409S and they said a damn strange motor its a late 62,should be in a 63 car but theres no X or casting codes it been decked ported balanced the whole yards 425/hp heads so write for pics.

Bob, the boat specs. came from me. It's from a Chevrolet Motor Division booklet dated 1962. I would think many of the marine co's of the time had there own variations though, depending on intended use, and some may have just used over the counter crate engines (car or truck) retrofitted with there own marine pieces.

[bobs409]

Thanks Crawler. I knew it came from here but couldn't remember who.

I used to have a pic of 2 boat 409's from ebay but lost it. They look quite strange with the boat parts on like the exhaust manifolds.

Thanks for pointing out the differences. Many of us often interchange the terms. It's a semantic thing, and generally we understand the use based on the words surrounding the term.
That's because we are smart (or "heuristic") when we process information, not binary and sequential like computers (or "algorithmic").

Here's what my friend drives: a "hay engine". Know what that refers to ???

Enjoy,

Actually a motor is any device that converts energy into mechanical motion. An engine is a specific type of motor that uses a comubustion process to get mechanical motion. :)

[348NUT]

I use both terms but I tend to naturally say motor. I guess they are both correct. Engine is just more descriptive. I'm pretty sure we all know what we're talking about.:)

Hmmmm! Would that be a four legged conveyance that produces road apples?:confused:
