I'm fixing to install a side exit corsa through hull exhaust system on my 1989 Century I/o with a mercruiser 350 magnum. Where I'm going to place the tips, they will sit right at the water line at idle. I have plenty of Slope up to my risers to avoid reversion, but I'm curious how water will flow over the hull when I accelerate to get on plane. When you start from a dead stop, the bow rises and the stern dips slightly. Consequently, the tips would be momentarily submerged. As the water flows down the side of the hull and over the tips, will this cause any problems? Just want to verify before I start drilling holes. Thanks!

I don't see an issue many boat builders put them right there, but no expert. To find out issues I would suggest talking to Corsa, they have been very helpful when I had questions
