What size conduit under deck??

[JohnC]

Working on a 77 MA. I'm ready to place my conduit in the box stringers but I'm not sure what size I need for the engine harness and transducer cables. My motor will most likely be the Suzuki 140B, drive by wire.
The footprint of my console is around 30-32 inches wide, not enough room for a 3" pipe to route completely inside of the stringers. 2 1/2" is pushing it and I haven't been able to find the pipe anywhere.

Has anyone an idea of the size of the new Suzuki harness? Is 2" pipe enough?

I imagine 2" is plenty for the transducers but I'm not 100% on that either. I've never seen one over about an inch or a little more. 12 pin Airmar/Garmin tilted element and a sidevu/downvu transom mount.

Both cables will be pulled through after everything is glassed in and done. Both runs will have two 90 degree turns. Hoping to get this right the first time!

Thanks
