What is this wire for?

[Dersu Uzala]

I just installed this 1988 evinrude 90 hp on my boat. Does any know what these wires are for? Should I connect them?

Tan is usually an overheat wire.

Wire to your temp sensor mounted in the head

Check for continuity with a meter between the end where it was cut and the block. It should be open on a cold engine. If not it may be only a defective sensor. Follow racerone's instructions to let us know what shape the engine is in also.

Others will I'm sure have answered before me but that's the overheat sensor for your buzzer

Yea those dang alarms that keep going off. But if I cut this wore I don't have to listen to that annoying beeping when I'm going wide open!!

FYI to the OP, at least that powerhead is NOT a 1988 Evinrude model. I don't know if the powerhead is a large mismatch versus the model tag on the midsection.

It is important to get this accurate info so you don't go ordering certain parts that are wrong on the powerhead you have installed.

The powerhead looks like one from 1978 to maybe mid 1980's when they still put the lift eye on the 90 HP motors.

Would have to see more of the powerhead to narrow down the year model.

Powerhead appears tp be 84 or older.

I am no expert like the others but when I saw it I was surprised to see he said it was an 88 I thought it was early 80s myself. Y'all confirm what I was thinking

Interesting that they cut the Wire, as a couple of inches away, are the Knife Connectors, inside the Sleeve next to the finger
