There seems to be MANY questions about this topic so......here's a couple of helpful quick-checks. Some have been discussed, some haven't.
Remember...."if it leaks in....it will leak out". Mostly all of these checks can be done on the trailer in your yard!!
If you are getting water in the bilge it can come from a number of areas....
-1] Motor mounting bolts. NEVER turn the shank of the bolt when checking torque, only the nut. Twisting the shank will break the sealer. If you've done this, the only PROPER way to re-bed is to remove the motor. You cannot get new sealant between the motor and transom unless removed.
-2] Thru-hull fittings. I've seen the sealers break-down. Simple test. Put the drain plug in and fill the boat from the inside. Look for leaking around the base of the fitting.
-3] Livewell leak. If a leak is suspect, install a plug at the outlet, fill the livewell and look for water accumulation in the bilge.
-4] Rivet or hull leak. Install drain plug and fill boat to the level of the floor.
-5] Rubrail. Most 'glass trackers are built with a "shoe-box" deck-to-hull joint. If you are getting water through the rubrail, a high pressure hose sprayed from the inside out will more than likely show the area that has a seal breach. The rubrail must be removed completely {not just the screws}, and the joint re-bed. All screws should be re-sealed as well as the BOTTOM half of the rubrail. You have to remember that all boats FLEX, and it is only a matter of time before the elasticity of the sealant breaks down and becomes brittle or stiff, then looses it's ability to seal.
-6] Transom mouldings. As with the rubrail, these are prone to leak over time. Be sure that all edges are sealed. This is important as you don't want water entering and rotting the transom.
-7] Backwash. Have your fishin' buddy watch the water closely as you come off plane. On some boats, you can literally FLOOD the boat from the wake. I might as well mention now that this is a huge issue with water entering the fuel system on boats equipped with fills at the transom, near the motor well.
-8] Anytime a screw is installed {or removed}, use the appropriate sealant to keep water out.
I use 3m 5200, Boat life Life Caulk or Life seal when doing any leak repair. You CANNOT use regular silicone. IT MUST STATE FOR USE ABOVE AND BELOW THE WATER-LINE
