I have an outboard (Yamaha F80) from 2002. The corrosion broke through the block and the water entered the cylinder..

Now I would like to buy a second-hand block but I would like to ask first about the differences between these two blocks.
The right block is like mine.. the left has some pipe hose on the cover (see the image)..

On the left block, there is a sticker with 6D7 - 1019391
On the left block, there is a sticker with 308686
What do you think? Can I reuse the left block or is something else to check for?
