Install Hour Meter - HELP!

[Broncojim1126]

Well I Have never worked on boat wiring before, so please bear with me.

I have a 2004 Hurricane Deck Boat, With a Yamaha 115 4 stroke. The boat doesnt have an hour meter, so I got one the other day and I would like to install it. In the instructions it said to just take power from a source thats switched when the key is in the run position or ground thru an oil pressure sending circuit.

Ok the back of the gauge has 2 flat terminals. Where can I pull power from that wont cause me to go insane trying to decode the spagetti mess of wires behind the dash? Do I just pull a hot wire off of something, cut the wire then re-solder a terminal on that line with a little extension line to go to my hour meter? Ground to the common ground strip?

Heres pictures of my under cowl.

What is the antenna looking thing and what are the 2 terminal strips?

Looking at your first pic. If you could test those two terminal strips with a mutimeter to see if either is hot with the key you could go off one of those. Or if you plan to mount it in the dash you could again with a meter test your gauge wires to find the positive and piggy back off of one of the other guages for power. you could also find the common ground on the gauges and use it. However the reason for using an oil pressure switch is so you get true engine hours. If you just use the ground in your guage circut then the hour meter will run whenever the key is left on.

Does anyone know where this pressure switch is on a yamaha 115TXRC?

Pictures would really be helpful.

Ayuh,... Just jumper it from a purple wire from under the dash,...
That should be the ignition circuit, which is powered by the keyswitch...

Your Yamaha is a two stroke engine so it has no oil pressure switch. Look at the back of any gauge. You will see a terminal marked "I" (for ignition). That terminal is hot when the key is on. Hook the POS lead from the hour meter there. Look at the gauge again, you will see a terminal with a "G" or a "ground symbol". Hook the NEG lead from the hour meter there. Done! The hour meter will register any time the key is on (so don't leave the key on when the engine is not running).

Your Yamaha is a two stroke engine so it has no oil pressure switch.

It's a 4-stroke.

It's a 4-stroke.

Oops -- I was looking for the "F" (as in F115)
