“72” 19’6 pump in floor bailing trough
« on: May 23, 2018, 11:25:04 PM »
First time poster/ longtime lurker! Not real confident scuppers are going to be above the waterline when all is done, you know. Had a idea to re-purpose the glass box mounted under the vent in the bow that I am getting rid of. Custom fit and going to glass into the trough so a automatic bilge pump(SeaSense 800gph) will fit. Also adding a 3 way switch to operate manually. Positioned dead center because I did not want to disturb my glassing of the stringers to the transom. What do you guys think before I glass it in? Photos in my member gallery. Cheers Tom

Welcome aboard!
That's a novel idea.  Are you going to have a bilge pump down below?
Back in the day when your boat and my 170 were built they didn't include bilge pumps.  They relied on the bilge being sealed from the deck, so no water could get in.
When I rebuilt mine I added a 1000gph and plumbed it through the stringer to the starboard side and have the output about where the badge is on the side of the hull.

Yes sir, going to add same identical pump in the bilge below the floor. Both will pump out starboard side as well. The previous owner abandoned the self bailing feature by drilling holes in the trough and letting the water go directly to the bilge to be removed by 2 pumps. As you all know the wood in the transom is/was not completely sealed from the factory plus the open access for water to get into the foam in the stringers. Wish I had found this site before I bought the boat. Oh well, got 5 years of use before I figured the transom needed replacing and than the foam in the stringers. Surprisingly the original floor was solid! Shame I had to remove it to get to the stringers. So the plan is to get back to the self bailing floor feature but figured the extra pump in the trough/channel might be good insurance. Anybody else try this approach?  Oh yeah, if the boat your considering buying has a full length transom piece of 1/4 thick aluminum bolted to it ,well it's not there just for looks or "extra" support. It is the support because the wood in the transom is shot...lol  The bonus is I found this site with all the great posts that has allowed me to have a fun project and escape to the garage once in awhile. Thanks ClassicAquasport!!!!

Yeah, that 1/4" aluminum is just to make the boat prettier, especially when the aluminum is new.  :laugh03:

had an old robalo that was setup the same way, small pump in the deck trough and a bigger pump in the bilge, worked great. 
The only thing I would suggest is putting the biggest & best brand pump you can afford in the bilge - small boats react worse than big boats with the same amount of water, you'll want a big pump when the sh#* hits the fan.  I wouldn't go less than an 1100, preferably a 1500 in the bilge.  Also if thats the thin plastic corrugated bilge hose in your pic might as well ditch that too & get the good stuff.

I'm assuming you have replaced the transom.  If so, have you considered removing the trough and extending the floor all the way to the transom and drillind the new scuppers at the new floor height?

Too late!, I already cut the marine plywood to fit and glassed the underside. That is great suggestion to raise the scuppers to new floor height and abandon the trough. Not sure why I thought I had to save the trough. I guess I can still make that happen after the fact if my current build gives me issues. Also will go with suggestion to upgrade the below deck bilge pump even though my plan is it never sees a drop of water, yeah right!
 Seen this splash well on 19'6 on Craigslist. Going to add to mine since I am getting pretty good at glassing.
This splash well along with the deck pump should solve all of my water issues I had before.



Also will be using 3M4200 to seal the tank hatch and the wiring trench. No screws
Open to any and all suggestions if you got em. Cheers T

I'd consider a bit of re-engineering. Removing the trough will increase the chances of keeping your feet dry. I bet that water in Michigan is COLD.

Here is my thinking if your interested. I drive my wife and friends up the wall with this stuff. This pic is what was happening before I started the rebuild. The scupper is sitting 2 inches below the waterline, the floor is about 3/4 inch above the waterline. That aluminum plate weighs about 50lbs. All of the transom wood was completely soaked and rotted and probably adding a lot extra weight. All of the foam in the stringers was completely soaked also, more extra weight. That's a 120hp Johnson that I will repower with a Mercury 115hp Pro XS, weight nearly the same 265lbs round about. Raising floor one inch. My plan/hope was the original scuppers will end up somewhere near the waterline and maybe a 1/2 inch of water will sit in the trough if it makes it past the ping pong ball scuppers I will add also. That automatic bilge pump kicks on when the water is at 1 1/2 inches in the trough. I keep my boat in a slip at a marina with shore power. I only have a cover for the console right now. New custom mooring cover for the whole boat almost cost as much as half the new motor around these parts, no bs. So I figured it was a good idea to keep the trough to house the small automatic pump for the big down pours we get once in awhile incase the scuppers get overloaded. I will add the splash well I mentioned earlier if the scuppers are in good position and can handle extra weight at transom. Oh yeah I moved the 50 gallon fuel tank bout 6 inches forward to help the situation. I made the tank brackets adjustable if I need to tweek the tank position. Have to bite it on the fuel hose if I am totally wrong. Some research I've done lured me this way. That's about it. Cheers T

Just a thought, why not finish your repairs and see how she sits in the water.  As long as your scuppers end up close to design spec, an above deck pump is not going to do much for you. 

The 196 has been going to sea for over 40 years without requiring an above deck bilge pump.  Most of the scupper issues are when a couple of heavy guys stand right at the stern.  As long as your repairs bring your boat back so where close to original weight, and your primary bilge pump works , you should never have an issue while moored. 

A better use of a second bilge pump would be a back up located in the bilge.

10-4 good advice, yeah I think I am going to wait to drill the scuppers too until I am completely done with new motor mounted. Like you say see where she sits in the water and go from there.
