I've had used jet boats where the previous owner had some real interesting silicone sculptures on the transom adapter and it still leaked.
Yeah, that's what I'm getting at. The amount of silicone is not as important as where it goes.
I want to get it somewhat decent looking and be on the water. I don't want to add more silicone to the mess and regret it later but I do want to be on the water. This boat used to be my dad's best friends who died of cancer. It's been around for a while and it would be my first jet boat.
