Welcome to iboats, good to have you aboard. :welcome:
It looks like it could be a 1977 model if your numbers decode like others... Yes I think that is it! Do a search for your model number and you will find breakouts for your engine and parts still available too.
likely a 1977 model.----Changes were being made in the 77 / 78 model years so you need to shop carefully.---------Unlike previous year models of the 25 hp with a 22 cubic inch powerhead , the 77 model used a 30 or so cubic inch powerhead.-----The 77 may have a different spline than earlier models on top of the driveshaft.----It may be more difficult to find a lower unit.----Post pictures of your motor as that always helps in these " i need situations "
