Hi I use my sportster 4tec 2004 in salt water with no problems. I also keep it in the water all summer still with no problems so far. My dealer said with the closed loop I shouldn't have a problem . We shall see. I also had the bottom painted wasn't to happy about that because I thought i would lose some speed. I clocked on my gps top speed with the wind almost 47 mph and when I was taking it out for winterizing one final run I clocked 45-46 mph. I will run the same test this year.because there is no trim adjustment do you find porpoising a problem when dooing in swell or does it ride fairly well?
Also I am curios about taking this boat in the ocean if anyone has experience please tell me about it.
