Very little uniformity between engine manufacturers and boat builders. Even today most engine manufacturers have a standard alternator for their motor, but not uncommon at all for the boat builder to use something completely different if their needs differ.

They used Prestolite or Motorola also.

Most prestolites and Motorola’s are the same thing. Many early marine Valeo’s as well. Would not want any of the above on anything I own.

Do you have parts or service manual for that 305K? Those would likely list the alternator,

Here's a slightly better pic of the alternator:

Check the number of alternator wires/plugs dangling on your motor against those needed on the offered alt.

For future use: Always a good idea to note all info on the part and wires being removed , diagrams are good too and pics better.

Hope they find the original and fix it , or the replacement fits, takes same wires and works well. Obviously it would have to have a conventional ( single or double?) v-belt pulley.

the one in the 2’nd link looks to be a presolite/Motorola. Absolute garbage by today’s standards. Back in the day they were the easiest to make spark shieled, but not all that great to begin with. If one of those comes on my shop it’s getting swapped for a Delco every time. Nothing crazy on the wiring.
