Hello all,
Getting ready to put in some new bilge pumps in my 280 Sundancer. The boat has the Rule 1100 27D models and I'm putting in Rule 1100 27DA pumps. Unfortunately, the pumps use different mounting-bracket designs, but the screw patterns are the same. On all of the guides I've read, many suggest to use a mounting plate and to never drill into the hull, but since the old ones are drilled directly into the hull, I think I should be fine to re use the old holes.
On the mounting-bracket, I saw some type of white/yellow sealant used. It was oozing out of the screw holes as well as all over the bottom of the mounting-base. What new sealant should I use when I screw the pumps down? Would 3M 4200 work? I was thinking about coating the screw threads and bottom of the plastic base in 4200 and then screwing it down. Does this sound like a good idea?
I did tons of searching online and couldn't find anything pertaining to using sealant AND directly drilling in a bilge pump mounting bracket, so hopefully this thread can help others as well.
Thanks
