I am putting my boat (72 grady white / 78 Johnson 140) in the sound next week for the first time. I have been running it in the local lakes for a couple of years with no problems. My question is what extra steps should I take for safety and what is the best way to clean it out afterwards? It will be in the water for about a week. I know I need to flush the motor, do I just use a muffs and a hose? Any other suggestions.
