Guys, just got this from OSE and want to install in my DF29 Mono hull. I plan on not using the rudder pickup and using this to provide separate cooling paths to the ESC and motor. My question is, do I mount this so that the raised square area, the surface with the actual ports is just coming thru the hull or do I drill two clearance holes for the barbed fittings and mount the whole thing to the underside? I got pics for reference. This is for a sports boat, thanks in advance!

i believe that you cut out a square so the bottom of the pickup sits flush with the ride pad or "bottom of the hull" if you please.There's a hole at the center of earth where the rest of the world sinks but i stand still... -
Thanks! Would you know if it should be closer the V at the bottom, or can it be up towards the side?Comment

my preference would be towards the middle or "lowest point" of the V, but i haven't used those before. I'm just basing that on where a V hull seems to make consistant contact with the water surface.There's a hole at the center of earth where the rest of the world sinks but i stand still...Comment

Got it, that makes sense to me and was the direction I was thinking. Thanks for the opinions, helps a lot!Comment

Help, Bail Faster!! There's a hole in me bloody boat!Comment

The general area looks about right just make sure you get it flushed with the ride pad. If it sticks out a bit when you glue it in, you can grind it down a bit, making sure to be careful you don't grind down to the hull itself. I've had no experience whatsoever when I did mine but the way I did it worked out great. What I did was place a piece of paper covering the hole and taped the the edges of the paper so it wouldn't move. Then, I put a piece of flat wood or anything flat that can cover the area so it acts like the piece that you took off. . .YIKES! ! Tape that as well. Then I flipped the boat over to the side with the pickup..leaning it in some weay making sure it's flat with the surface it's on. Then I placed the water pickup making sure it sits flushed against the flat side of the wood covering the hole. I glued it in and I maneuvered it in some way where I was able to put something with some weight to weight it down and let the epoxy do it's thing. A few days later I removed the piece of wood and the paper that stuck to the pickup was removed easily. Please remember this is how I did it with no experience or anyone to show me. When I saw the hole I was so scared that I screwed up because that hole shouldn't be there. .lol If someone can chime in(after you've probably had your laugh. .lol) and give you/us a better method would be great, as I would like to know an easier and better way.Comment

Very similar... First, I made sure to make a very precise hole. This thing doesn't have much of a lip on it. I ground down the port side until it was about 0.015" proud. Then I put a radius on the front side to help funnel water. I got expos in it now for the water seal, but don't trust that completely because of that small ledge. So tomorrow I'm going to throw some fiberglass and Z-Poxy over the top, inside the boat, to strap it in.
I'm going to not t use my rudder pickup. My thinking behind a dual port on the ride pad is the water inlet pressure should be identical. So if I get a choked down flow rate on the discharge of one of the water circuits, I know it has to do with that particular circuit, not the pickups..
Thanks for the ideas, it really helps! Yes, I'm with you, it ain't easy to put a hole in your boat!! Just goes against nature!Comment

I'm glad I'm not the only scared s******* when doing this for the first time. Also, just want to say it's nice to have you as a very active participant and contributer to this forum. Even though you haven't been here that long you've contributed greatly. . .nice and thanks.Comment

It's nice to be appreciated, thank you! I have learned so much. You know, I put in over 40 hours, just reading what people have done, as I collected ideas for my Hydro build, the first in a very long time. Just as it feels you get to know an author when reading their book, I felt that way about a few people. I read so much of Properchopper he seemed like my new best friend, lol! Anyway, this is a great forum and I'm proud to be one of many among its collection!Comment

Hole in Bottom Fixed!
A happy ending, the dual port, thru hull water pickup has been installed in my DF29 and ready for the water tomorrow. Going to meet and run with some new people in Tulsa, really looking forward to it!
From the bottom pick, you can see that it is slightly raised with a blend radius up front to catch plenty of water. Slight speed hit, but good cooling ain't an option for me!Comment

I've used these and I will reiterate comments above, I would be sure it is flush with the hull.
I've blue printed quite a few hulls and have seen the difference in handling after removing very subtle irregularities.
The way it sits now, raised, makes me twitch a bit and I predict one of two or more handling issues:
1) left turns push the bow in hard or other strange behavior
2) straight lines it may lean to the starboard
I suggest working it flush. If you happened to ding the hull while working it down, bondo is a great filler.
Good luck!"Look good doin' it"
