Evinrude 60HP VRO 1990 temp.

[duke3]

Hello out there.<br />I have a small question.<br />Is the cooling water temp. around the temp.switch, the same as the cooling water there is comming out of the pea-hole.<br />The servicebulletin according to outlet of cooling-water to the pea-hole from the top of the motor, hase been done.

The water from tell tale is suposed to remain cool. It does not circulate through block. <br /><br />Its only purpose is to show that water pump is working. It does indicate that water is circulating through block howerver.<br /><br />The water that is around the temp. sensors are the same temp. as water to thermosttats. <br /><br />If thermostats do not open water becomes hotter and sets off alarm triggered by sensors when they ground out therby seting off warning horn with constant tone.<br /><br /> Indicating an overheat condition.<br /><br />Water from tell tale can become heated if their is a restriction of hot water comeing thru thermostats back down exaust leg. <br /><br />Or if the combustion tempetures go shy high because of lean runing condition. Water becomes heated while on its way up thru water supply tube from water pump.<br /><br />When this happens motor is about ready to blow a hole in a piston or worse.<br /><br />Bottom line....water from tell tale is to always remain cool.<br /><br />If it isint....sometings wrong!<br /><br />Good luck!

Back a month or so ago Boat Boy asked Joe Reeves if water from tell tale is before thermostats or after thermostats.<br /><br />Joes answer was!....Before thermostats! and this is true for all models of OMC/BRP outboard engines.<br /><br />Hope I didnt misquote you Joe. If I did then please correct me.

"The servicebulletin according to outlet of cooling-water to the pea-hole from the top of the motor, hase been done."<br /><br />I've done the same on my '86 70 horse Johnson. Since then, I've noticed an increase in temp at the telltale hose that I didn't have when the water came out of the original outlet on the lower side of the exhaust cover. It's not burning hot, just warmed up pretty well. I attributed the temp increase to the fact that the water is now coming out of the exhaust cover thus warming some. At idle, I can touch the thermostat and block without burning myself and at idle on the muffs, water isn't coming out of the exhaust ports (my hand will get wet if I hold it over the ports). BTW- My old thermostat would let water through the ports at idle.
