I have these on my 525 and they work well. Engine sounds great but it doesn't bother those outside the boat.

Here is a video of me running one of my 565hp engines on a stand with the mufflers!

Everytime I recommend Aqua Power Ltd. mufflers to boaters, I always usually hear back that they had great results and no loss of power at all. Worth checking out.
