Temperature, pee hole, paint, water draining

[i ski]

Hi all,

I just got a 'new' engine to replace one that was on the boat when I bought it. The 'new' engine is a 1977 Evinrude 115 HP V4, 2 cycle, model 115799S.

First question...One of the temperature sensor wires is disconnected. It does not appear to have ever been connected. The Clymer manual I have states that some models of this engine were made with only one temp sensor, while others had 2, one for each side. I assume my case is the latter. How can I tell to be sure someone did not disconnect the wire? If it should be there, I would like to fix it. If not, I guess I'm okay with just one (as it was made).

Second question...Where is the pee hole? I have looked all over the underside of the motor and it is just not there. Where did they hide them that year? Most outboards are obvious, this one is not.

Third...I would like to repaint the lower unit. Is there any special paint I should use for this? I assume some type of high temp paint should do the trick. Or is it a bad idea to paint it at all? The current color is like a dirty brown (even after I cleaned it up). I want a flat metallic finish.

Last but not least...If I were to store the boat outdoors, how can I verify all of the water is out of it after flushing? Does it drain by itself? If not, what do I need to do? I am concerned about it freezing up and cracking the block.

Thanks...sorry for writing a book,
Jeff

1. Look on the top area of both heads. It should be obvious where a sensor would be. I thought they all had two.

2. It may not have one. If it does, there will be a tube going from the right (looking from back) cyl. head to the lower cowl pan. If it doesn't have one, I'll bet that right head is the one without the temp. sensor. Correct?

3. Use any high quality paint. The trick is the prep. Sand the area down. If you get to bare metal, wash it with a 50/50 solution of vinegar and water and then prime with Zinc Chromate primer. Any top coat will work. High temp. is not needed.

4. The engine self drains as long as it is in the vertical position. If you want to be sure, turn the flywheel (by hand) in the direction of the revolution of the engine. That will ensure any trapped water in the pump is gone.

I am pretty sure this engine has 2 temp sensors also. I have seen people disconnect the temp sensor because they went bad and the person didn't want to hear the annoying buzzing or replace the sensor. You should be able to test the sensors resistance with a multimeter. It is also possible that it just disconnected from vibration.

I just checked the parts books. The '77 shows one sensor and no pee hole. '78 shows two sensors and a pee hole.

If you want a pee hole, it's easy to install one. On the starboard side of the block, high up and close to the head gasket, there is a blank boss that is left over from the olden days when they had a hot water choke. Drill and tap that boss for a 1/8" pipe thread. Install a hose barb nipple and a piece of small diameter hose. Run the hose through a hole in the lower pan. If you want to do it right, the part number for the plastic pee indicator nipple in the pan is 321885.

Yep that's right. I've got a 77 85hp - basically the same thing.

One temp sensor, no tell-tale.

Thanks to all. Excellent information as always. I am now in the process of swapping out the two engines. Hopefully, I will be able to start/run the '77 this weekend. Somehow, the '77 looks like it is in much, much better condition than the original '88. It seems like the owner(s) really took good care of it. I'll let you know how it works out. Fingers crossed...
