raw water scupper removal

[BobCT]

Both of my engine and my A/C pickups are partially clogged.

I'm trying to remove the scupper on the bottom of the boat. I cleaned them up and have 1 screw removed on each side. I have some movement now in the front but I don't see a third fastener in the rear.

It won't budge. Is there a trick to removing these?

Not sure how many bolts you are dealing with however, it will be bedded down in a sealant/adhesive compound, like 3M 5200, so don't expect it to be easy to remove even with the bolts out. Good luck. Just one of those more difficult jobs we undertake.

On one of my raw water intake for the engine, I have a piece of silicone trapped inside the scupper underneath the boat. I tried getting it with a pick but it's too big.

I have the exact same issue on the seacock for my A/C pick up as well. I unbolted this one from the inside but it wouldn't budge. I figured I would remove the scuppper/strainer from underneath but couldn't get it off either.

Is there a way to disassemble the seacock from the inside w/o completely removing it so I can clean them out?

thanks,
Bob

Not sure - but be sure to avoid silicone on re-assembly. 3M's 5200 is the only way to go. Silicone is not an adhesive - and will come off - while 5200 will actually adhere (one of the stickiest substances on earth) and last for years.
