Thanks guys! It pales in comparison with some of the rigs on this site but I am pretty proud of it.
Sandy, I ran the boat all last season with the updated engine room. I actually run the boat harder now because I have a better understanding of how things work. And, as my dad says, "they like to be run".
I'm not sure those mufflers do anything but they can't hurt I suppose. I have diverters installed on the outside of the boat to submerge the exhaust. It's quiet with the diverters but without them it's like I'm running straight pipes.
