Hello...I am new here....Great Site!!!

I have an '02 Yamaha 50hp TLRA that I just converted from tiller to 703 control box. Smooth conversion for the most part..for a rookie...However I have 2 questions:

1. When I removed the tiller wiring harness I unplugged a plug that goes from that harness and connects to the t/t motor and also a plug that goes to the oil level gauge. Do these two plugs connect back into eachother now that the tiller harness is gone???

2. When I turn the key to the "On" position the overheat buzzer goes off constantly. When I go ahead and start the motor the buzzer stays on. (If I disconnect the plug from the oil level gauge, from my question above, the buzzer doesn't sound in the "On" position or while running.)

The motor is "peeing" , thermastat appears to be fine, and plenty of oil in the oil tank. Only had it run hot one time in the past after being in shollow muddy water, changed out the impeller and fixed that.

When I use to run the motor with the tiller I always thought it ran a little warmer than other motors I have owned.

*Note* I have only test run it hooked to the water hose for about 30 seconds because I don't want to damage anything due to the buzzer going off.

I can provide pictures or wire colors to simplify questions above.

Thanks in advance!

Re: tiller to 703 conversion help!!!

sorry ment to say 703 control box....

wires in question are the Green and Green/Red on the female connector coming from the oil tank guage and the Pink, Gray, and Black on the male connection. Do these plug together now that the tiller wiring harness is gone?
