I feel like an idiot, but I cannot figure out the year of these motors ?

[MuskyHunterDave]

Hey . . . Guys

I went and grabbed the serial numbers off the two motors that came with the cat I recently bought, and I did search the net and links offered here, but i could not figure out what year they are and model for the small one

Smaller one is: model ??
Searial: A1419814

The bigger one is a 800EL i Believe:
Searial: 1376538

Thanks again "in advance" for the info

Happy Holidays
Dave

The smaller, the A should be a 86 or 87 can really tell as it should be 6 digits not 7 so they is a problem there. The 800 is 1960 inline 6 cyl by the number.

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

Well I double checked the numbers, and that is right . . . A1419814

They are both inline 6 engines, and look like the same era? ,do you know the HP's as well ?? I would imagine the 800 is an 80hp? what HP is the other one (A1419814), and I would really like to figure out the year and model on it as well ?? The guy I bought it from said it was a 35hp, but as rediculous as this may sound, did they make a 6cyl 35hp ???

I have always been an evinrude guy, so I know nothing about these old merc's . . . .

Thanks again "in advance" for the help

Happy Holidays to all
Dave

Yup, there's something wrong with the serial number.
But, I have seen the odd prefix.
The A shouldn't be there if it's the same vintage.
Going with 141xxx would make it a 1962.
If it were 41xxxx it would be a 1975 which would be too hard to mistake.
Axxxxx would put it well into the 80's making it a V6, also hard to mistake.

Is the cowl white?

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

If you omit the A it could be a 1961 70Hp 6 cyl inline, if you look on the starboard side of the engine block there should be a name cast in it also a block part number, if you can find them they will help.

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

Not sure in on that vintage, but there could be a serial number on the welch plug on the side of the carb. Might be too early for that (?).

 

[Laddies]

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

It'd to early, should be stamped in the top of the engine lock above the exhaust plates

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

Well I was thinking more 1960's for both of them as they look almost the same but one is a little smaller. They both have the black metal band / cowling that goeas around them.

I attached some pictures, the first is the 800 and the rest are the A149814 motor in question The smaller motor has a pull start on and the 800 does not I believe. I have bigger pictures if needed . . . .

I Looked at the block and on one Cyl it says:
"Full-Jeweled"
"Super Marathon"

Then stamped a couple cyl down is the number "832-1815"

Does that help to figure out what year it is ??

I did not see any numbers on top of the block . . . . as later stated

Thansk again in advance for the help / info

1962 or 1963 model 1000.
Serial # range 1464949 thru 1665001.
Since you're toward the beginning - 1962.
Is this the one that is "slightly bigger".
1960-1962 the motors were white with a black cowl.
1963 they started all black.
You should also have a Mercury logo halfway down on either side of the cowl.
But I s'pose a lot can happen in half a century.

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

No this is the smaller one (seems to me) and it has the elctric or pull start top end. You know they are both 6cyl (at a glance the motors seem similar)so maybe the one is just a short shaft with smaller mid section, thus the "seems smaller". DUH

Are you sure on the numbers?? Model 1000 doesn't that mean itis a 100hp ?? are the 80hp and 100hp motors that similar ?? I AM CONFUSED . . . .

Did you look at the pictures of the motor I attached in the last Post ??

They are both all Black

1962 or 1963 model 1000.

Yep.
Go over to www.oldmercs.com
They have some pictures and serial numbers for Mercs made before 1977 - back into the 50's.
A pic of the front name plate might help too.

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

Alright, I searched the link you sent me, and I believe now it is a 1961 Merc 700
So both are 1961's and one is a 800 and the other a 700

After scratching some paint, I did determine they have been white.

My Serial (minus the A) is 1419814 and the website stated Serial numbers 1413611 thru 1436114 were 1961 700 models.

So actually there is probably not much difference between the 700 and the 800 . . . is there ??

Thanks for all the help

Merc made a 70 from 1960-1962 with a white body and black cowl.
The '61 fits in the serial number range but that's across the product line.
BUT - the 70 was a 3 cylinder.

The inline 6's were pretty much the same physical size.
If you have a short shaft (15"), you got something there...they are rare in bigger engines. Maybe one is 20" and the other 25".

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

Well CRAP . . . What the &$%# is it then as it is a 6cyl not a 3cly, but it looks like that 61 700/70hp and the serial number fit. . . ARRGH

What did you mean "that's across the product line" ? 3cyl versus 6 cyl ??

As I said it looks like they both may have been white at one time, or atleast part of each motor ??.

SO we know for sure the other (bigger) motor Serial: 1376538 is a 1960/61 800EL / 80hp that one is good to go . . . . .

I attached some pictures of the lower unit on the unknown motor (short shaft?) and the front panel for the motor as well.

The lower unit is off the A1419814 the one we cannot identify, how would I tell if it is a short shaft ?? What do I measure I forget ??

I am pretty sure the 800EL is along shaft the lower unit is off of it as well, what do I measure for that one as well ?

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

Okay . .. I measured each motor from the bottom of the engine cowling down to where the lower unit bolts on and the 800 measures 20" and the "unknown" motor measures 15"".

Is that where the measurement needed to be made, and does that mean the Unknown Motor is a short shaft ?? Plus if this is the right way to measure it, is the 800 at 20" considered a long shaft ??

Thanks again For any and all the help

HOLD THE BOAT . . . . . I have been doing some digging, and I believe They did make a 6cyl 70hp so it must be a 1960 model 700 . . . . . . . I see it was also called a Super Marathon Six by Mercury

This is a breakdown on a model 700 6cyl, and while the 700 is not on my front plate, everything else looks the same, and the serial number matches.

Anyone else wanna comment on this ??

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

A coupleposts back I said it was a 700 here's a link with the block number. Mercury did not build a 1000 till 1962 and the starting number was 1503332.

Wow.
Uncle. I give up.

Re: I feel like an idiot, but I cannot figure out the year of these motors ?

Well this is all been a little confusing to me not being a merc guy, but after using your link (thank you), and checking block numbers, if you click the 800 6cly link it offers two perameters for ranges of serial numbers and the serial 1419814 fits in between the second group. once clicked and double checking the block number 833-1919 IT MATCHES, so it seems to me it is a 800 as well.

Could someone who knows comment on the lower end measurements I stated in my previous post . . . If I measured it right It looks like I have a long shaft 1960 800EL, and a 1960 800 short shaft, would you agree ?

Also, it was mentioned before that a 1960 80hp short shaft is a rare item, is that true ???

Thanks again "in advance" fo rany info

Happy Holidays . . .
