    Engine operating temp of 185?

    I recently bought a 1980 ericson 38 with the original Universal 5432 diesel with 4k hours, and I'm trying to decide if it has an overheating problem or not. The previous owners said the engine temperature gauge should be at 160f, but when I motor around it climbs up to 180-185 at 1800-2000 rpms...

    Universal M-18 adding high temp alarm

    Seems like this is something that someone has asked before. Let me know if that is the case. I would like to install a high temp alarm on my 1985 Universal M-18. The only one I have found is on Catalina Direct. While fine boats, mine is a 1985 Ericson 30+. I spoke to the sells department at...

    Transmission temperature guage

    Last year my new ZF15 transmission lost all it's fluid and the forward bearing on the input shaft siezed, bringing the engine to an abrupt halt. The engine temperature guage showed 185-190 degrees at the time, about 25-30 degrees hotter than normal. The tranny itself was hotter than a fritter...

    Fixing Temperature Gauge on Universal m25xp

    My temperature gauge is busted, was busted all last summer. Promised myself this would be resolved before I go back in the water. Does anyone have a link to a good article on the trouble shooting steps to be find the problem? I have never looked at this part of the diesel system and have no idea...

    Temperature Gauge Wiring

    The previous owner of my E29 had disconnected the Water Temp gauge for the Universal A4--as he believed it had a short. I have searched the web for a wiring diagram for the four terminals on the back of the gauge--with no luck. I actually tried to remove the gauge from the panel but it seems...

    Steamy smoke and high running temperature

    On our 1989 E34 Universal M25XP with 1260 hours on it, we noticed a steamy exhaust and higher running temperatures when cruising at 2300 plus rpm. I did the usual - change raw water pump impeller, clean out raw sea water strainer, check sea water flow, nothing helped. When we last arrived at the...

    Temperature & Oil Pressure Alarm

    I would like to add an alarm circuit to the temperature and oil pressure guages/sensors on my Yanmar 2QM20. Cole-Heresee manufactures an alarm with transducers (sensors) but I would require two sets of oil pressure transducers and two sets of temperature transducers. I have no idea how I would...

    Universal M15 temperature

    I have a 1983 E28+ equipped with a Universal M-15 diesel that insists on running hotter than spec (which is 150 degrees). The engine is set up with a closed coolant system rather than use raw seawater for direct cooling. Would this "modification" cause the engine to run hotter (say 175...
