I am redoing the dash in my baja sport 250 and there is no good way to get mechanical k plane indicators installed to my liking so I started looking into the electronic sending units for the k planes, they are not cheap to say the least. so I got to thinking, why not make my own sending unit? why couldn’t I grab an extra 2 trim gauges, some 25 dollar a piece sending units that come on mercury outboards, a couple of 3 foot control cables and fab some brackets to mount onto my inside transom to hold it all together? I am picturing a piece of plate aluminum with an arm of some sort attached to the sending unit with the cable attached to the arm and the plate. I am pretty sure I can do this and make it look very clean and make it so that I have just regular gauges to install on the dash with no cables being a pain. I already located the matching trim gauges I need for 60 shipped, 50 for 2 cables and 50 for 2 new sending units so 150 for all new parts, figure another 20 bucks, even 40 on the high side in hardware and I can do this all for 200 bucks. mechanical indicators would be around 200 bucks for a used setup anyways. has anyone attempted this before?? am I crazy for thinking this??

check out the electronics forum on here -- there is a thread started there

thanks!

this is what I have in mind

How about trim sticks? The Mercruiser sending units never held up for me in the past. Mechanical is set it and forget it.

Why not do something like this??

Replied to your other thread but thought I would mention that along with installing the K-planes on my 250 ES, I installed a set of Stainless Marine LED indicators to the right of the helm on the top of the gunwale. The installation was straight forward and they were well situated and highly visible. Overall they were highly reliable and effective.

I think that may have been another guys post. here is my dash, its not possible to go on the side

i bet you could fit a set of trim sticks on that little shelf next to where your can is sitting in that picture.

is there something similar to fuel sending units that would stand up to being in water?
