It may or may not. A lot depends on the condition of the inside of the block. I would say it would be worth getting it out and pulling the t-stat housing and block drains to see what the inside of the cooling system looks like. If that looks good then pull the valve covers and see what it looks like inside them. I will say that is not a marine engine, but a car engine dropped into a boat. It looks like a EDELBROCK performer intake(looks like performer cast into it in front of the distributor), the water pump is an early GM short pump(definitely not a marine pump), and that is an auto style carb as it still has the decal valve on it.
