Hornet FF Install

Installed a Lowrance 4 into SloMartins Hornet during lunch today, here's the result.

I tacked a short length of threaded stainless M5 rod to the transducer bracket which made life so much easier than previous installs.
Slice of teflon for topside
The usual excess 438 metres of redundant cable wouldn't fit in the moulding, so popped a slot in the hull, well above water line, and tucked the bulk out of the way, the cable-tied bundle wedging snugly between the finder scupper and the tray moulding. Left enough in the moulded scupper to allow for future adjustments in head unit position or upgrade. Note the two orange cable ties, which prevent load on the through-hull sealant (only a token smear needed as the hole was nearly airtight anyway - Use a cable tie to draw the doubled cable through the hole, spreads the load better than cord or fishing line).
Power lead was likewise squeezed through an equivalent diameter hole - no sealant required; Round cable, round hole... :P

The rest is self explanatory.

From lifting the yak off the roof rack, to lifting it back on was just over 40min and powered solely by two bacon butties and a bottle of Green Beret.

the only thing left is to get it wet first thing tomorrow and see how quickly the hornet sinks :)

Mate, this was a huge help in getting my Hook 4 installed on my Hornet

Thanks for the photos etc.

While mines not as tidy as yours it seems to have done the job!

Thanks for this thread and the photos. 40 minutes? I've spent two days just thinking about it!
Does anyone know if a side-vu/scanning transducer can be tucked up against the bottom of the scupper like this one is and still scan OK without the hull affecting it?

I'd set it up on a temporary rig and compare results on an identical line, say, between two mooring buoys.
Start low, and keep tweaking it up until you lose the periphery, eg mooring blocks at the outer edge of the screen.

Then drop it down a smidge to give you optimum sidescan with minimal exposure to damage.

Thanks, yeah will go that route and it gives me the option of easily and quickly removing the lot too.
