Not sure on yours, but on my 1985 85hp Force just above the themostat housing on the top to the right as you are looking at it there is an 1/8 " stainless pipe plug that looks like a screw. depending on whether it has been used in salt water or not it my be kinda hard to remove. this is ware the sending unit goes (electric). Hope this helps some.

Re: water temp gauge

Although I cannot give you the answer I believe you are hoping for as far as how to go about installing a best method to monitor engine temp. There are ways to go about installing a temp gauge. However, one method requires the removal of the overheat thermoswitch in the cylinder head to make way for a probe of a battery powered remote digital thermometer. Performance of the probe pretty much requires that the probe be placed in the same location as the overheat thermoswitch and that it be epoxied into place. Although, cheap and realatively easy to install, getting rid of your engines overheat alarm I believe may not be a wise idea. Grumpy II mentioned the water plug located ontop the head directly above the thermostat housing. Some people use this location to install either a tell tail or as I decided, to install a dashboard mounted pressure gauge to monitor water pump operation. Although, neither method monitors temp. Such methods do allow for keeping an eye on whether or not water is flowing through the motor which does offer some comfort in that aspect. It also allows one a manner in which to tell when your engines water pump maybe worn or faulty by noting a decrease in pressure over the life of the engine.

It is much cheaper and easier to add a tell-tail to your motor, please refer to this thread http://forums.iboats.com/showthread.php?t=210027

As long as the water pump is operating correctly, the engine water temperature will only be few degrees higher than ambient intake water temp. With tell-tail you can always confirm that there is water flow in your block which is all you need. The impeller does not generate high pressure, just enough to circulate water around the cylinders and exhaust manifold.
