2016 240 DAUNTLESS; Water Seeping from Screw Fastener Hole
Posted: Fri Jul 21, 2023 5:45 pm
I recently purchased my second Boston Whaler boat, a beautiful 2016 240 Dauntless with only 260-hours on the original engine. When using the boat, I noticed the cockpit sump pump was not automatically coming on, and the float switch controlling the pump was hard to trigger. I replaced the original SAHARA pump with a newer, MK2, version of the same pump.
When I removed the original sump pump, I saw water seeping from the now empty mounting screw holes in the hull liner. The water continued seep out for several hours. I am now waiting for this water seepage to dry up before I install the new pump.
The sump pump I removed seemed to be original to the boat. I did not notice any sealant on the screws holding the pump cage down.
Q1: should I have concern about the water seeping from an empty screw fastener hole for a cockpit sump pump?
Q2: should I contact Boston Whaler regarding the water seeping from the empty fastener hole?
Q3; should the screw fasteners have sealant applied when I install the replacement sump pump?
Q4: should I use 3M4200 ADHESIVE SEALANT on the screw fasteners?
Q5: should I use Silicone sealant on the screw fasteners?
