112F ...Cool????

[NigelzFling]

Hi,<br /><br />Just took my 115hp evinrude V4 1994 for a run after fitting a Temp Guage to each block.<br /><br />First for the good part, both Temp Guages read the same temp...that's good. <br /><br />But, they only read 112F... from what I've read on this forum they should be a lot hotter... <br /><br />I bought this boat 2nd hand, could this mean the T'Stats could have been removed?<br /><br />Looking for help <br /><br />Thanks<br /><br />Nige

Possible. Where are the senders located?

To confirm the temp you need to get some temperature sticks or use one of the "guns" as the temp might be OK & your guages might be reading a bit low. Those motors don't like to run cold - - or real hot for that matter.<br /><br />However I assume that is a salt water motor and since it it new to you I suggest that you do the t-stats & pressure releif valves, water pump, plugs, change gear oil, deflectors in the block and new filter on the fuel filter/water seperator. If you don't have a manual check here:<br /><br /> http://www.theoutboardwizard.bizhosting.com/parts_service_and_owners_manuals.html

I was told that when the motor is operated a higher RPM the poppett valves open and by pass the thermostats and the motor temp will be about 20 to 25 degrees above the water temperature. <br /><br />I had a 50 hp evinrude and drilled the head and installed an electronic temperature gauge. In cold water at higher speed the gauge would barely show anything. In warmer water It would show a little more. When at an idle or running a slow speeds the temp would come to about 140
