Removing Corsa Mufflers Need Help Removing or Gut Them?
#11
Are you sure they used 5200? That is generally something you use for a permanent installation, like a swim platform that is below the waterline. 4200 or just regular marine silicone is usually fine for thru hull tips. Also, if Formula didn't already do it for you, now would be a good time to get some resin and glass in the openings where the tips pass through the transom. That way, if you ever do develop a leak hear, the water will pass relatively harmlessly into the bilge instead of wicking into the core of your transom and rotting it out.

Guitar string is what we always used to remove windshields back in the day. You pull it back and forth to "saw" through the sealant. Even though you might hit the studs, you may be able o get enough of it off to minimize gelcoat damage. Maybe use this method combined with a few of the others to get them off.

I think I hit the center rod or bolt with the die grinder when I was in there... It was pretty rusty and came apart fast..... I had lots of rust inside and wanted to get rid of everything inside as it was in bad shape..... TBF

Rust Inside? Thought these were full stainless steel? For the $ they should be!

I bought my boat with no engine and the exhaust was still in the boat attached to the corsa system..... Obviously the stock 502 exhaust was gone but I was surprised to see rust in the diverters and tips.... I had to replace the diverted valves as there was not much left of them and it seems the pieces that broke off sat for years and caused the rust. But with some work and new parts it all cleaned up well! Salt water is nasty and I am a big believer in using salt away after every use..........

I am planning to gut my silencer tips on a 28ZX tomorrow with a plasma cutter. I have one tip off and want to see how it does in the shop. I am hoping to do the other 3 while on the boat. Anyone have any experience with this??
