I bought 2 new drive showers for my 303 SR1 and I have a problem now with the clearance below the swim deck. The silent thunder box hits the shower. I purchased Rex marine showers. They work awesome from what I have been told. I do run longer distances and feel I need them. I don't know If I should modify the exhaust box or set the tailer trim stop lower or sell them and forget about it. I would appreciate any ideas are suggestions. I have considered cutting holes and putting in bowls or some kind of box to allow for the clearance. I have thought about new exhaust mufflers to allow for the clearance of the drives.
