Best way to check wooden stringers???

What's the best or easiest way to see if you're stringers are rotted or not?

take out one of the lag bolts that hold the engine in should be able to tell pretty quick whats goin on in there

Well of coarse visual is the first. Second would be lightly knocking on them with a hammer so you can get an idea of the condition inside the stringer. There will be a different sound between a solid peice of wood and one with rot or water in it. I wouldn't recommend probing or poking into the srtinger as this is just a way for moisture to enter later unless it's sealed up afterwards. Push on the sides and look for movement.

Thanks guys

Is it a Tige before 2002?

Prob wood

no, it's actually the boat in my prof. pic. Its a 1984 Ski Nautique 2001

Try tightening (lightly) the motor mount lag bolts. If they feel stripped, the stringers are gone.
