Thru Hull locations?

[BCRider]

I thought I had everything planned out and was ready to drill my holes for my new thru hulls. I'm glad I saw the other thread that mentioned the wakemakers install videos. I would have dropped my new holes right in front of my paddle wheel/transducer which is a big no no. So, my question is I've now moved over my locations by about 4" closer to the middle of the boat. Where the middle of the 2 hoses are in the picture is inline with where the transducer is. The hole closest to the transducer will now be approximately 12" away. Could I still potentially be interfering the water flow to the transducer? The transducer is just past the engine mount shown in the picture. With all of the other OEM thru hulls in place I don't really have many options of where I can put 2 new holes. All of the existing is also all 3/4" and I'm installing 1".

Depending on the type of thru-hull you are using. With a low profile mushroom, the turbulence are minimal. I still like to avoid being in line in front of the paddle wheel, but the further forward of it your are, the less it matters. Given where Tige places the wheel, you are hard pressed to put a t-hull in its path, thats very close, because you would be right under the engine mount.

Thanks Chpthril. I am just using a low profile thru hull. Do you think it would be alright if I moved them back inline? The reason being is it completely changes and simplifies the set up of the thru hull, ball valve, and the pump as I can pretty much come straight up compared to where i have them in the above picture which is Thru hull, 90, union, ball valve, union, 90 up, pump. Any minimum distance I should try and keep?

Looking good... I will be starting these tasks next week as the weather out here wouldn't let me jump in the boat yet.... Are you putting inline check valves on your drain/vent thru-hulls? I know that I have seen some but chpthrill said they shouldn't matter so long as the T-valves are above the water line... At least I think that is what he was saying... Anyhow.. looking forward to seeing your progress! Best of luck and thanks for your input on my thread...

I will have check valves between the pumps and the bag for the fill lines. My vents will be T'd in to the existing which I just crossed left to right to stop passive draining. At this point I wasn't planning on putting check valves on my empty pumps as the only time water could run in to the bag would be when that side is listed and already full. They are also dedicated empty lines. They don't share with a vent.
