190 Thru hull fittings

[Redman79]

I posted this in the restoration section but thought it might be better to get some advise from Champion owners. I cleaned out my bilge are today to find out that the live well pump thru hull fitting has been loose and the live well re circulation thru hull fitting had a crack in it both failing and leaking. so the small piece of plywood these fittings go thru is pretty wet. I dont think this piece is connected to the transom because from what i can tell the transom is dry and solid stringers are also very dry and solid. ( i have a fan blowing thru the holes hopefully it will dry up nice)With that beings said i have read somewhere not to use stainless or brass thru hull fittings is there a reason for this? Also i have looked and the only thru hull fittings i can find that is recommended for below water line is brass and stainless. What are the best thru hull fittings yall recommend? And is there a special procedure to installing? 3M 4200 im assuming?

I used stainless and I sure do hope nobody gets on here and gives a scientific explanation as to why stainless is bad; because I do NOT want to ever re-do mine!

I used the same ones 86 inches used, different name on the package; but they were the same.


There was an mention of the metal shrinking in that thread, plastic shrinks in cold too,almost everything shrinks in the cold.

I got my Thru Hull fittings in and im gonna install this weekend. The wood was soaking wet and has dried up pretty good i think. with that being said do i need to do anything to the plywood before installing thru hull fittings with 4200? I have read and watched people (you tube) using epoxy around the hole, let it dry and then use 4200 on fittings? Is this something i should do? or will the 4200 keep it pretty dry? I dont have any epoxy resin handy but i could get some if i needed to.

I epoxied mine with the epoxy from west marine. Several thin coats. Seemed to make sense at the time.

I’m not telling you what to do, but I’m just gonna make a suggestion from experience. Did you heat lamp the holes for a week or so, if not you really might want to make sure it’s really dry first.

had a fan blowing on it 24/7 and kept my garage about 75-80* for over 2 weeks. I did not have a heat lamp on it. As small as that is(just guessing prolly 4"x8") i didnt think it would need it. I will get one an put it on there if you think i need to.. Just to give me some piece of mind that plywood piece is not connected to the transom correct? from what i can tell inside the hull it is separate.

I’m not positive how they are constructed exactly, I know my 2005 is tied together because I had wet foam that was draining to the transom and out my left transom hole. But maybe you got it dried if it’s not wet anymore.

If you do a search in this sub forum you will find that the guys that know about this sorta thing are very adamant about drying the transom with heat lamps. Double check but I think they say two weeks.

I would do it. If you seal it up with moisture still in it, it will rot. The heat lamp can completely dry it and save the transom. I think you need to pull the top trim piece off to do the heat lamp thing.

I pulled the trim piece on the top of the transom last night. it looks to be fiber-glassed over. i just bought the boat last month and i plan on taking motor off and resealing the jack plate holes. I will put a moisture meter on it at the holes and see what it says. i will hold off on putting the thru hull fittings in until i know for sure if everything is dry.

Stick a piece of wire (or toothpick) down into those screw holes and see if it feels solid or comes out wet. I like your way of thinking and playing it safe and taking the time to make sure it’s fixed right.
