Our boat club have inherited an abandoned boat (Scorpion 21) complete with MerCruiser engine which was pretty much neglected by the previous owner in our yard for 3 years. We have now fully acquired ownership of the boat and engine from the previous owner and are working on a project to make the boat sea worthy again for our members use.
I have a list of items we'd wish to purchase and I know the best way to identify the appropriate parts list is via the engine serial number - this I cannot find ................ lol
I've taken some photos which would perhaps help identify the unit. Or I'd be more than happy to look for / advise / photograph in greater detail & quality anything that may be of use to help identify and purchase all of the parts below please? (is it permitted to upload or PM those?)
Also I've noted the following markings (it's an inboard GE 3ltr straight 4 cyl assembly / sterndrive / zdrive)
GM ENGINE CASE MARKING 4097080 \142 01 & HH IA 8068686
STERNDRIVE PLATE REF 0B685475
ZDRIVE PLATE REF 0B655907
? CANT FIND SPECIFIC ENGINE PLATE REF
**Update Thursday - Last night the lads working on it thought that the motor was much newer than the stern-drive serial numbers, but we noted the serial plate is missing due to the prev owner using an after market starter with the wrong fitment shape & he welded an arm on right where the plate marking should be - we could see the pins. On disassembly last night there was another faint marking on the engine that looks somewhat like a Mercury part number starting 1M0621--- ? (then some weld marks). But I cant make sense of that number in the Mercruiser serial tracker list either - its very frustrating. Really appreciate any guidance gents. Thank you so much.
