Need help with ID of Merc lower unit/gearcase

[southeast_scrounger]

Found this at an estate sale...measures 19" from bottom of skeg to top of cav plate, about 25" overall from stem to stern. Has a sticker with the number 14 above the zinc mounting area. Any idea what it fits? Thanks!

Get the numbers on the inside of the casting on the top of the cavitation plate

Thanks...the numbers inside are 1667-9010-C8 with 413 stamped by the rearmost bolt hole. Hope this helps!

Looks like later style 6 case, but, then again, all I play with are old inline 6's...not worth a heck of a lot without the guts...

It's a gear hsg fr a newer 3 cyl--70,80,90 and 4 cyl 100-115 125 type engines there are many variations that are designated by a letter with a numeral after the 8 numerally part number so I can't really tell ex tact engine it will fit
