Hot not burning.

Water from the tell tale should be approx the same temp as the source, as the tell tale is plumbed in pre-engine water flow.

Re: Telltale temperature

Hi, Roly.<br /><br />Some engines have the telltale at the input to the cooling flow. Those telltales will be at lake water temp, as Pro Crappie Guide says.<br /><br />Other engines have the telltale at the outlet of the cooling flow. Those telltales will get hot.<br /><br />So, it depends on what engine you have, of which you have told us nothing.

Cheers Guys.<br />Yamaha 80Hp 1989. & I'm told it is pre-plumbed so<br />I guess its ok to be same as source.<br />The hi-temp alarm went off at sustained 5k revs so<br />I guess a new thermostat/impellor kit would be advisable.<br />I am looking at buying the motor and this appeared at sea trial. The compressions were 130,128,130,; so seems pretty tight.<br />Thanks,<br />Roly
