OQ

This is what I used...

Top is sh 40, bottom is the thin walled stuff. You can see the difference in wall size, more inside dia.
At this store 1.25 is the largest.

Ok, yeah I seen the thin wall PVC stuff in 3/4" and it's hard to find but I have found it on the web in a flexible coil looking stuff for a ton of money. Thank you for finding that Capt. UB

I think I am going to use the grey electrical PVC stuff cause I can sand the outside and it matches the dark grey lockers. :D That I will be painting with almost a work boat finish.

Chase tubes should all be as large as you can possibly fit in the boat where they are going. Minimum 1" for fuel lines. I have one 1 1/4" chase back to the bilge that carries too much, and pulling everything through was extremely frustrating. Could have easily ran 1 1/2" or even a 2". I did use 3/4" flexible plastic conduit for individual runs like running lights, radio antenna cable, and deck lights. Sweep elbows as opposed to streets.
After I read your post I checked the clearance I have above the stringer and the tank well bottom. I don't want to cut into the stringers if at all possible due to already down to the minimum 3". But I was able the slide a piece of 1.25" PVC easily in and out of the opening.
Was going to use this wire X3 to wire my 3 pumps.

The two bilge pumps have floats and then my tank well pump will also have a light on the 3rd wire. All 3 of them will share the same chase tube. That is 3-14 gauge wire in a sleeve, I would think it could fit in a 3/4" PVC but like I said I will get the wire first.

Just so it doesn't hold me up I ordered the triplex wire (3/14) and the main power wires. It was a lot cheaper to order two 20 ' 10 gauge than to order 10 feet of 12 gauge duplex. If I need to I can run my main power wires through a nylon sleeve from a winch cable I have. It will be in the same chase tube as the engine/trim harness.

I posted this on one of your guys boats a few weeks ago. 2-21/2 for controls, 11/2 for main electrical. 1" for depth finder. An 11/2 for all electrical to the stern. This will carry any thing you might come up with, Bilge pumps, bait pumps, lighting, etc. And a 1 184 fuel line. So that is 5 the minimum that Cracker Larry and I came up with 10 or 12 years ago. .You can always add and extra if you feel a need. Never put electrical in with mechanical.

Tom, I was planning on running my shift and throttle cables along with my steering down the starboard gunwale. Transducer wire will be routed down the port gunwale where it will be away from any electrical and very easy to upgrade as needed. That leaves me with just a chase tube for the fuel line, one for the three triplex cables for the pumps and well light control and one for the main power wires, anchor light and the engine harness wires. What ever size tube the triplex wires go in I may run one extra tube of the same diameter for anything I may add later. I don't see anything but I will have it if needed. Once the foam is poured and the well installed I can't change my mind. I will have one drain pipe that will be at a slight downward angle to drain anything coming from the fore deck lockers. It will have a 4 way tee for very small drains at the front of the sole for any water that may find it's way going the wrong direction.

Oh, I also ordered a 10 gang ground busbar. It's more connections than I need but has room to expand.

Once all the wires and hose are run do you guys seal or cap the ends of the chase tubes to make sure there is no water getting in and if so how?
