what are you using to seal exhaust pipes that go through the transom? Life Calk? 4200 fast cure??

Any good waterline sealant inside and out and then on the outside should be the sealed trim rings.

Never had any issues with life seal and it’s easy to pull apart when you need to.

dont think i can use the sealing trim rings as my pipes come out very close to the bottom of swim platform and the two center pipes are to close to each other

You’re in Naples? What boat?

2008 fountain 33 lightning, have had it for a month

Awesome. 496s? They are cool boats. Gonna be out this coming weekend? A bunch of us are thinking of going to new pass. It’s by lovers key just north of Naples. It’s got a nice spot to put the bow on the beach and 8ft of water at stern.

yes 496 Ho's , might try to make it. Have to seal up those tail pipes this week. let me know what day
