I saw this crack on the main stringer at port engine. It's at the inboard motor mount area. 8.1 motor. This not my boat but a boat we are looking at. Any concerns?

Im not an expert and take this with a grain of salt but that kind of just looks like a superficial crack in the paint or top surface. I don’t think there’s gelcoat there

Don't fall in love with it. People do that with cars, motor cycles, boats, machine tools, etc... and it clouds judgement.
That said. Have it thoroughly surveyed.
Wet wood swells.

Usually, and probably . . . a crack in a stringer is indicated of the core (wood) having retained moisture and is expanding. Looks to be early stage, but worth looking into before jumping into the abyss.

Hard to tell without a good moisture meter or drilling a hole into the stringer.

That large black hose running from the top to bottom of the photo looks like it has seen better days. Lots of cracking below the clamps.
