the good ole speedo doesnt work.... i pressurized the little tube and the guage seems to be working.... then i realize that something is missing? the tube should be attached to something to pick up water right? so im sure this thing is broken so where would i find this bad boy? im sure i cannot find the same one so what are my best options withougt hacking and making big holes? also i notice the temp gauge didnt work, so i have 6 volts to the sensor... shouldnt be 5 volts? i ground the signal wire to ground and the guage spikes all the way up. i noticed the lowest reading on the guage is 140... either my boat is running colder than 140 at silverwood or the sensor is messed up. next time out i was going to bring a multimeter and measure ohms while its cold and when its warm.... you guys have a easy way of testing the engine water/coolant temp sensor? heres a pic of the speed pressure tube thingy
