I surf the port side all the time and it is pretty nice. I just have a 750 in the port trunk and the center 350 tank (stock) full and possibly whoever I have in the boat in that corner. I usually ride with just 2 or 3 people including myself. I wouldnt fret it. The keypad issue is hit and miss but expect to replace it every 5-10 years, mine was done before I got it. It is about 300-400 depending on where you get it and what year you have.
The ballast system, well, who cares, it will all get redone anyway lol. I did a malibu type setup with antisiphon valves and I wont waste my money on puppies after doing it this way. I love my setup.
I did have my gateway go out and that was 650 or so, but that was about it. I gotta run but maybe I will post more.
