Does a 1988 Evinrude 70 have SLOW?

No SLOW on that.-----Install a new impeller if you do not know condition of it !-----Find the tan wire on the cylinder head.-----Slide the rubber cover back to expose connecter.-----Turn key to on.----Touch the connecter to the block.---Horn should sound.----Does hose for tell tale come off the side of the block or the top of block ?

I recently purchase a 1988 Evinrude and was wondering if it had SLOW on it. Also how do you test the overheat horn on this boat.

That engine does NOT incorporate the S.L.O.W. feature.

The warning horn should beep momentarily (1 second self test) when the key is turned to the ON position. If it does not, find out why or chance disastrous results.

(Testing Warning Horn)
(J. Reeves)

On VRO equipped engines where the VRO automatic fuel/oil setup is still being used, make sure that all components are connected as required. This would include the VRO pump wiring harness itself, the oil tank wiring, the overheat sensor(s), and if so equipped.... the vacuum switch that is standard to many V6 & V8 engines.

If the VRO automatic setup has been eliminated and has been disconnected properly, and the fuel and oil is being premixed, make sure that the overheat sensors are still connected, and the vacuum switch if the engine is so equipped.

On engines prior to 1984 which have no VRO setup, ignore the instructions pertaining to the VRO components, etc above.

Turn the key to the ON position (Engine Not Running). Find the TAN wire at the cylinder head(s), then ground out the portion of that wire that is part of the engine wiring harness. If that Tan wire connector has the knife type connector where as it is exposed simply by sliding the rubber insulator back, it does not need to be disconnected.

Grounding that TAN wire should cause the horn to sound. If it does not, find out why as that's the only warning you'll receive should the engine overheat or have some portion of the VRO system fail, or have the engine encounter a fuel restriction if it is equipped with a vacuum switch.
 
There was a sevice bulletin in 1994 that indicated that the telltale fitting should be moved to the top of the block.
 
I have a 93 70hp Johnson that this was updated on. I see no where to put the telltale out the top of the water manifold. Any suggestions.
