My name is brnewbie and I am an idiot. I grew up boating with my dad and I just realized that he did not teach me a whole lot. Long story short - I bought a used bayliner BR yesterday. I was so excited - mostly for the excited look on my five kids faces at the prospect of a summer of skiing, wakeboarding and tubing. They were so excited. We piled in the vehicle and launched the boat. I practiced the little I remembered however, I was unaware that the seller had detached the water hoses when he winterized the boat. We ran once up the lake (3 minutes) and when I idled down, water was present on the rear floor of the boat. I kept it at a slow idle and limped into the ramp. I turned on bilge to empty boat. Total time on water about 5 minutes. Boat still fires right up. I tested a couple of times before I realized where the water was coming from. I took boat to marina to get serviced and looked over. I feel like an idiot. I did not know any better and ran the boat with hoses unattached. What likely damage did I do? The engine temp appeared to be OK. The dealer said it would take several days before they could get to it. The wait is killing me. I had to share my stupidity.
