| If you live in the Boston area, call Mack Boring (617-848-9300).
They are located in Braintree and have been most helpful with
questions on the Yanmar.

| 920.2 | maybe WATER PRESSURE? | CADSYS::SCHUMANN | | Fri Jul 22 1988 11:12 | 19 |
| > Does anyone have any guess what "WATERPROOF" might mean?
Are you sure that's not "WATERPRESS"?. To figure out what
this light means, follow its wire back to its sensor. The position of the
sensor on the engine should give you a hint as to what it measures.
If it measures water pressure (to verify coolant flow), and the coolant
is flowing, but the warning light is on, it probably means a defective
sensor. From your symptoms, it could be that the switch in the pressure
sensor may be a bit sticky and/or corroded. The second time you start the
engine, there will immediately be coolant and pressure, and the vibration
of startup may be enough to unjam the switch. It is also possible that
the pressure and flow are marginal, due a failing water pump or some other
problem. Since engines are expensive, it would be wise to verify that the
coolant flow is adequate, and to replace the sensor if it is defective.

| 920.3 | You have a saildrive ? | HAEXLI::PMAIER | | Mon Jul 25 1988 05:09 | 6 |
| Do you have a saildrive? If yes,then "waterproof " means there is
water between the two seals of the "leg".

| RE .1 I called Mack Boring. They claimed there is no such indicator
(I said "yes there is", they said "no there isn't", I said "yes
there is".......)
RE .2 The problem finally reaccured so i could double check this.
The indicator definatly says WATERPROOF.
RE .3 I don't think it's a saildrive. It's just a shaft with a prop
on the end. Isn't a saildrive a unit that looks like the lower half
of an outboard?
I guess this weekend I'll trace the wire to the engine and see
if that tells me anything.

| 920.5 | info about panel and wire? | CASV05::THOMAS_E | short!! | Wed Aug 17 1988 11:19 | 8 |
| I have the Yanmar Technical manual and may be able to help.
What type control panel do you have? With or wothout the tach?
Which indicator light is coming on? I.E., the Nth from port or stbd.
Do you recall the color of the wire?

| 920.6 | As best as i remember... | OURVAX::NICOLAZZO | Better living through chemistry | Wed Aug 17 1988 12:16 | 16 |
| It is the control panel WITH the Tach. The panel is mounted on
the port side so it looks like this;
<--------stern bow---------->
X X X ENGINE TEMP WATERPROOF CHARGE
(don't know what
these light are)
I think that's the sequence of the lights. I'll check it this
weekend to be sure. I don't know what color the wire is, I'll check
that also this weekend.
Thanks much.

| 920.7 | Marblehead YANMAR dealer | YACHTS::CORKUM | I'd rather be sailing.... | Wed Aug 17 1988 14:06 | 16 |

Hello Rich,
I too have a Yanmar 2GM and I'll check my panel (with tach.) as well.
There's also a YANMAR dealer in Marblehead, Rich Phelan (Marine Power Systems
639-2248). He's located next Marblehead Trading's yard on Cliff st.
(This used to be where Bob Cloutman was located and I believe there's a small
yacht club there as well). He's a one-man operation but does good work.
I recently had him upgrade my salt water cooled engine to fresh water cooled.

| 920.8 | Ahhh, the answer | OURVAX::NICOLAZZO | Better living through chemistry | Wed Aug 17 1988 16:42 | 11 |
| Well i called Marine Power Systems. They said that the light is
for a saildrive and is an indicator for what .3 had explained. They
also said that the wiring harness for all the engines are the same
so although i don't have a saidrive the wiring is there and it must
have shorted out on something.
Guess it's time to go crawling around the engine compartment, what
fun:-)
Thanks all

| 920.9 | Book Sez... | CASV01::THOMAS_E | short!! | Tue Aug 23 1988 11:56 | 5 |
| I checked the technical manual and from right to left it shows;
charge, oil pressure and water temperature.

| 920.10 | .9 partially correct. | CASV05::THOMAS_E | short!! | Thu Aug 25 1988 09:55 | 11 |
| re .9
Shoddywork on my part!! sorry. :-(
Re-examination of the manual shows the waterproof light as the 4th from
the right(as you face it). There is no discussion of the indicator in
the text of the manual about the waterproof indicator. Presumably it
would be discussed in the manual that came with the Saildrive?
