First let me say that I bought a seaflush last week – a little reluctantly. I figured I could just build my own for a few bucks or pull the intake hoses and extend them and drop them in a bucket. I could have tried to do that, but I was sure happy to have the seaflush. It made the job so easy and that in conjunction with your video on barnacle buster already saved me thousands of dollars that the yard was going to charge me to start ripping apart the coolers to solve an overheating issue. A couple of hours of work made easy with the seaflush and the motor is back running at normal temp.
