Welcome and congrats on the new Stream! Unless you documentation of a full rebuild, I would be more concerned about replacing the core, stringers, transom, and floor before anything. That plate on the transom is almost always a bandaid for a rotten transom.

Check out the rebuild/resto section here and you will see lots of great info on rebuilding these things and if you have any questions, please don't hesitate to ask.

Hi Guys(and Gals) I'm Mike from South Jersey.
Fell in love with vipers as a kid and have recently been watching for one.
Stumbled across a Viking close by and couldn't pass it up. So my 1st Stream is a 79' viking with a 79' Mercury 200.
Motor is on a transom plate with no set back and prop shaft about an inch below pad with a 24p big ear chopper. Standard water pick up on lower.
Over winter probably do the Bob's nose cone and low water pick up and a jack plate.
Plan for this year is to build a fuel tank and rear bench seat and run it.
Hope to learn a lot from here and from trial and error. Hopefully less from error! lol
