I am wanting to buy a used 2001 yamaha 2 stroke 150hp. The dealer is doing a compression test on each cylinder. What should I consider as acceptable compared to when it was new. THANKS

All cylinders should compress within 10% of each other. Psi is typically over 100, but that is not the important thing.
