drain hole configurations?

God
Can you guys post some pics of your drain hole in your transom? I have one hole that I have drilled already for my garboard or bulge drain. Me and REEL talked about this already and he mentioned putting 2 drain holes for sump well on my floor,1 hole for each side of the motor bracket. All advice is welcome. And yes I know I will have pics up soon to better explain

I'd like to see the way you've configured yours 1st hand...floor level inside vs water level outside the hull will dictate what kind and where drainage...from what I can tell, bilge pumps will be muy importante!!...:party:
 
I don't know if I'm saying this in the correct terms. But I'm not putting back the actually free floating type splash well. I'm keeping my transom open except for the 3 walled splash box I'm building off the floor around my sump well the height of the 25" inch sides of my transom. Sorry if I'm using the wrong terms. Did yall actually put 2 drain plugs down in the sunken box in the floor? I'm also putting a bulge pump in this recessed hole also to pump out deck water. Do I need to build this 3 sided raised box off the floor? I'm kinda second guessing my original design now. I mean they had to have drain holes in these recessed wells to drain while on land or trailer.

If I understand you correctly you are planning to have a splashwell that reaches all the way down to the floor? If that's the case, I'd reconsider..... the deeper the well, the more water could come in and the longer it would take to drain.
 
The 3 sided box was gonna have a half moon in the front and half moon cutouts back at the transom to allow deck water to drain back into the recessed sump well . But the 3 sided wall or splash box would also keep a lot of water from coming over the 20" part of my transom and flooding the deck. Kinda like a hybrid 25" inch transom. I put the recessed sump well in the floor the get rid of the imediate water off the deck. Then pump out with a bilge pump when needed. And if in a bad situation I could pick up and run and pull the 2 plugs to drain the water quicker along with the sump mounted bilge pump.

I would have to fab one up and really didn't want to lose that room in the back with a bulky port to starboard splashwell. My floor ended up 3/4 of an inch higher than factory height. And with the light weight 135 HP I might be able to get set with ball scuppers.
 
you just thinking to much!! my old v just drained all to the bilge and i would just pump out when needed, i had my boat filled to the gunnles and it still floated you will never have that much water in there, unless there is something bad going on like me with a 10 foot wave!

so as they say, shut up and fish!:thre:
 
Here is what I have as of yesterday. the other picture is the style of wall or "splash well" i want to build around the sump well in the floor.There would be three half moons cut out at the bottom of the wall to let water from the floor drain into the sump well. I would also have flot switch operated pump in the sump well to pump out water.

The pic on the right is what I call a normal splashwell and is the same thing my V has factory... the only difference is that it has, and I suggest building, a floor in it that angles back to floor level at the transom and draining it through the transom instead of into the sump... then whatever water hits your deck would still drain to the sump and be pumped out.
 
like Maco joe said im thinking to hard. what i kinda want to know also when the boat is on the trailer how does the sump drain from rain water? i take it there is a drain plug i need to drill in that recessed sump well? I apoligize for asking all these questions but the po had the transom set up all wrong he had the sump well draining into the bilge, and the only other v20 ive been on was my dads and it was a self bailing with a higher floor.
 
well generally if you have a sump (V-20's don't) the garboard plug drains the sump and there are holes in the sump going into the otherwise sealed bilge that you keep plugs in while in use but pull for storage.

If my suggestions are not what you want to hear, don't hesitate to tell me and I'll stop but I suggest that you get some cardboard and build it a few times.... adding an angled floor to your "box" to turn it into a splash well really is a negligible amount of added work and ANY water that you can make self drain is an advantage..... Honestly, as high as your floor is, I'd strongly consider covering up that sump and letting your deck just drain overboard. Leave the sump to just draining the under floor area....
 
Being a 74' hull I was told the floor is water level so unless I raised the floor I couldn't make it self bailing. So I installed the sump well and was gonna make it a hybrid type transom with a sump and a well type box built up. What I can do now is cover up the sump well with a piece of ply and glass it flush then cut out a circle for a 8 inch inspection plate and make kind of a dry storage in the rear. Then drill my holes for my ball scuppers and make it self bailing. The stern of this boat is lite weight and I don't think I will have a problem.

When wellcraft took this design from bilge-draining to self-draing floors, they raised the floor several inches and built the cap up several inches as well...you're saying you expect yours to be self-draining at only 3/4" above outside water level...plus the splashwell you're thinking about will only add weight in an area you don't want it...Smoke mentions having water drain into the sump to be bailed out by the bilge pump(s)...basically what I suggested early in this thread before there was mention of a splashwell...still makes sense to me...but a word of caution...WE are not there...YOU ARE...it's your boat and you know what you have in mind and conditions the boat will be used in...your craftsmanship is great...I wish I had HALF the skills you show...but the greatest workmanship won't forgive a poor design...
 
PICTURE #1 Hey guys heres the transom Im talking about. What year is this model? Where would I direct the deck water to drain? I now understand elevating and angling the splash well floor towards the stern with drain holes. Out of all the configurations I have mentioned which one should I go with? Guys thank you so much for all your help im sorry im asking alot of questions i have just busted my @$$ to get this boat perfect and I dont want to stray on such an important part. as you guys can see im at a point to were i need some sound advice. I feel comfortable building it anyway you guys seem fit.


PICTURE #2 Reel I raised the floor from factory 3/4 of an inch and Im not sure where the floor sits in comparison to the water now, All I know is that Im a whole lot lighter in the transom than it used to be. Also the picture you see of BLUES 74' Is the way i would really like to go with 2 storage boxes port and starboard and a single batter board conecting the 2 storage boxes and 2 scuppers in the transom i WOULD SIMPLY HAVE TO COVER UP THE SUMP WELL i GLUED AND GLASSED IN.

I suggest that you build the splashwell for now and leave the sump alone for the time being. Hang the motor and even if you can't run it, fill the fuel tank with fuel or water (yes it's a pain to get it dry but it's cheaper than gas) and take your batts with you to the ramp. Launch the boat and see what your water level is with the boat loaded as it would be in use... check front and back.... it MAY be worthwhile to locate the batts in the bow.

After you find your actual water level you can decide how to proceed.
 
I just measured my factory CC outboard self bailing deck. Best I can tell, the floor is 18.5" above the keel and thus 1.5" lower than the 20" transom.... just a reference for you to compare to. This was measured at the rearmost portion of the floor beside the splashwell. Also the top of the splashwell is 11.5 inches higher than the transom or 31.5" above the keel.

Yeah, Man...I thought you were going for the #2 configuration and the sump would have a weight-supporting grate over it for water collection and pump location...w/no need for scuppers and thru hulls...scuppers are great when new and unclogged, but if a particular design doesn't require them, IMO no need to bother w/them...and of this I'm sure...scuppers are best used w/an inside floor well above the water line...:party:
