Underfloor trunking and steering cable

Hi Folks its me again asking beginners questions for my humber project ......

I am now planning ahead my future moves as I need to think about purchasing my steering.

I want to put my steering in the underfloor trunking which will be located in the middle of the bilge just above current drain bung (see photo if needed).

If I wanted to use a teleflex NFB cable steering system it would mean it maybe difficult to route into my planned trunking hole due to the cable been quite stiff and the angle it comes out of the engine. Has anybody had any experience of doing this or know whether or not this is possible? Or does it mean I will need to purchase a hydraulic steering system meaning more money

Thanks in advance

Gareth

Not best route for teleflex cable Gareth to may bends to conquer successfully will be tight ,
Needs to be offset from top really

About here would be best bet without attacking any under floor strength of he deck not down in the well, seemy pic but move it over to edge ,if that makes sence can not edit on this, will dig out punter shortly if u need it,
See my orange dot move it to edge of transom knees

Forgot boat was on drive lol


Here ya go. Bare in mind I've not finished yet nor bolted down the take of pipe nor re located fuel filter , it's going in the console out of the way,

Do as this but off set it, if you wish to go lower as XS do where your bung is, hydro steering will be required, and still a bung needed here also

Steering Cable Routing


If possible the steering cable should be routed to the starboard side of the boat in order to balance engine torque. When routing the cable select a path with the minimum number of bends, making the bends as large as possible. Do not MAKE BEnDS LESS tHAn 8" RADIUS. Sharp or frequent bends will result in hard steering and premature cable wear. When necessary to pass through a bulkhead, a 1-1/2" diameter hole is required. The cable should be loosely clamped or tied for support at regular intervals.

Hi Ed, thanks for getting back to me. If I'm reading this right my options are as follows

1.) Trunking in bilge area like XS it will need to be a hydraulic steering

2.) Cable steering could be done if I go for trunking location like yours but will need to be starboard side biased with a minimum of 8" radius bends. Or if I go for cable steering will it need to be located on deck?

Thanks

Gareth

Was done by BHG in Lymington. I was told its designed as a stainless exhaust port for something bigger!

Martini I think has similar on his rig ....

I've just routed my cables thru a homemade aluminium overdeck cable duct (not as fancy as you underdeck guys but does the job), it's offset and steering moves freely. Gives you an idea of the bend involved.

Aaaaaaaaaaaahhhhh, I have been stressing over this trunking for awhile and am hell bent on not having the trunking overdeck. I now have a hydraulic steering system and want to get the trunking in through the bilge area just above drain plug (see 1st post photo) as I have access to a right angle hole saw. I am proposing to do the following:

All elecs through following trunking and gland - 2" (50mm) Black Flexi Hose Pipe 5 METERS POND KOI | eBay and NEW Boat Rubber Cable Grommet Gland Cone Steering Control Marine Witches Hat | eBay

And then hydraulic steering lines, fuel lines and oil pump pipes spiral wrapped and put through same cable gland as above.

I am now worried that as I don't have a bilge pump the bilge area will be full of water and the trunking/cable glands will be permenatly under water and not just wet fully submerged. Although I won't have any wire connections in this region I am not sure how good a seal I'm going to be able to get?

If everyone advises against this I could just get a flange and enter on the deck floor just like Peter M and Ed suggested

Thanks and would appreciate everyone's opinions

Gareth

You're going to be really pushed (IMO it'll be as near as dammit impossible) to get all that lot threaded through a flexible 2" ID tube under the deck.

I've just rigged my Opti, and the standard above deck rigging tube is 2" for the Optis/Verados. It only just fitted through the tube. You need much larger tubing under the deck.

You really don't want to spiral wrap it either. You'll have to remove everything to change one cable.

Whatever trunking you put in don't forget to leave a spare draw wire for future alterations / repairs
