I'm in the process of purchasing a 13' Whaler that has a 2005 4-stroke 40HP Honda on it. When talking to the owner he said that he uses it in brackish water and that he doesn't flush that often. I've always been under the impression that you should flush each time after using it in salt water.

I haven't bought it yet, so if there is an easy way to tell if I should run away, please let me know. He says that it runs great and I'll definitely verify that it runs smoothly before buying. I'm not sure how many hours on the the motor.

Should I walk away from this purchase?
