Step 1: Find the Source of the Problem

This process can be tricky, but you can do a few things to make it easier.

First, check for obvious signs of a leak, such as water damage on the deck or puddles underneath the boat. Once you’ve ruled out these areas, it’s time to get creative.

  • One way to find leaks is to pour some water onto the boat and watch for where it collects
  • You can also use a hose to spray water onto different parts of the boat and see where it comes out
  • If you’re still having trouble finding the source of the leak, you can try using a smoke bomb or candle to create an airtight seal around suspected leaks and see where the smoke escapes

Once you’ve found the source of the leak, it’s time to start fixing it.
