Thru Hull Exhaust help!

Hey all,

I am debating on a Thru Hull exhaust for my 2003 Seadoo 185 S/C. I am not considering this for performance upgrades, rather sound. Have heard a couple out on the lake and they sound great. I am wondering if this will create any issues down the road? Will water be able to enter into the engine or hull? Has anybody experienced anything negative with a thru hull exhaust? If so, what is the best solution to create the best sound. Thanks for reading and posting your comments.

Before I'd go thru-hull I'd try a free-flo. That way you'd keep oem exhaust location and hose. Just swap a pipe for the resonator. It's a deeper tone than stock...a dubba-dubba-dubba at idle no wake...does a have a drone around 3K.

The thru-hull is a raspier....more badazz sound...no doubt. But is definitely costlier and with another hole in the hull...this one real close to the waterline.
 
Thanks for the responses. I am going to look into a free flow as our location on the lake sees a lot of wake. Just need to find some videos or sound clips.
 
What does that matter? :confused:

I'm worried about the hole being at the waterline with the amount of wake that we see. I would always put it back on the ramp but when my family goes to the cottage they may not. Not overly experienced with the exhaust systems on these machines. I do have the entire winter to figure it out and get the parts I need.
 
It would not matter man, the hole in the pump area for the exhaust is at the same height as you would drill for your thru-hull. The thru-hull pipe angles up just like the factory pipe and no chance it will backflow into your motor. I had this on my rxp with 2 adults, no issues. If you go the free flow route there is a terrible drone.

How would this be affected if I had 3 adults on and the nose full of stuff.. We have boat access only and if another couple comes I do not take the boat on the journey to pick them up.. Also, if the machine is flipped how would that affect it? Just want to have all angles covered. Will help me to make the decision and not look back.
 
pwgsx,

The exhaust pipe from thru-hull fitting to waterbox does not climb as high as the oem hose.

Not saying that it's any more liable to get water back flowed into the wb.

As for the drone at 3K and up a bit...I don't spend any time at that rpm range so...not a prob for me.
 
It's high enough, water would have to be a foot above the foot well to even come in. Even at that the whole ski would have to be that low in the water for it to happen. It will be fine.
