Water leak found...how to fix?

[78LS2]

I finally found the source of my water leak; the raw water pickup's thru-hull fitting. I assume that the sealant used between the hull and fitting has gone bad, hence the leak.

It appears as if there is not enough room to spin the brass valve and various fittings off with the transmission in place. (2003 196) Is this the case?

If I can get the fittings and what not off, and remove the large brass nut inside in the hull, does the fitting/strainer screen on the bottom of the hull just push off from inside?

Thanks

Yes, the thru hull/strainer is held on by the nut against the hull but some strainers do have a couple of screws from the outside. Check to see if your's has them They are just there to keep the strainer from rotating making installation a one man job.

Do use 3M 5200 or 4200 as the sealer. NO silicone!!!!

can I get the assembly inside the hull off/out w/o removing the transmission?

You dont need to. Just raise the nut up, clean both surfaces, mate and retighten. You should have a least 3/4" of an inch to play with.

Because Silicone breaks down over time 3M 5200 and 4200 are Marine Sealents. 5200 is like a glue and is meant for parts that dont need to come apart, it is fast curing I beleive 3-5 days. 4200 is a selaent that seals as well but is meant to come apart more easily and dries more slowly re 1 week. I use the 5200 for all through hull or under water fittings.
