Thank you in advance for your input.
I recently purchased deck boat with a 2002 DF140 with 330 hours on it. I had the engine checked out by a Suzuki dealer and was advised that all was well. However the compression check was as follows, Cylinders 1,2 &4 were at 170 psi. Cylinder # 3 was at 155psi. The tech advised that it was within 10% so it was OK. I was caught up in the excitment of buying a new boat and had drivin two hours to look at the boat. The sea trial went well and so I purchased the boat. So far it hasn't given me any trouble.
Now that the excitment has worn off a little, I and concerned about the #3 cylinder difference from the others. Am I beining over concerned, or should I check out somthing else that may have caused this? Could a valve have build up? I have pulled the plugs and all looked the same and in good condition. Any in put is appreciated.
Thx
