Default Can someone look up my Mercury OB S/N?

This came on my "new" boat tonight. I don't know a thing about it except:

It has 4 cylinders.
It says 75HP on the case.
It's got Power Trim and Tilt

S/N is 6615354

Supposedly it ran 18 months ago. I'll be finding out soon how viable it is.

I'd love to know what the exact year and model name are; as well as the RPM range. I also need to know the exact weight of the whole unit; and if I can still get a manual and parts breakdown.

Thanks in advance!

Thanks again!

Here is some basic information on your engine that I could find for you.
Engine Serial number: 06615354 Engine Model number 1075625 MERCURY 75 ELPT
When you look up parts you will want to look them up under Service Literature for A 1985 MERCURY 75 ELPT.
The service manual part number you will want to find from a mecury dealer is 90-86134-4. Try googling this part number, It will come up.
