m18

We have recently purchased a new to us Ericson 30+. The mechanical inspection showed the thermostat didn’t appear to be opening. When we pulled out the thermostat housing it was full of a gelatinous white material. The thermostat definitely wasn’t opening. We are a bit fearful that the heat...

The M18 in my 30+ runs at less than 160 on the temp gauge. I have installed a new thermostat and new temp sender that I purchased from Featherman before he closed his business, but it still runs the same temp. Any ideas why it does this? I thought the operating temp was supposed to be 180. Does...

On the top of my exhaust riser there is a small plug similar to the plug that holds the zinc in the heat exchanger. There is also a larger plug on the port side of the riser at the bottom near the exhaust flange. What are the purpose of these plugs?

The temp sender on my Universal M18 may be dead. I tested the function of the temperature gauge and it appears to be OK. I used a multimeter to test the sender itself and the resistance readings do change as the temperature goes up, but no reading on the gauge. Torresen Marine sells a...

Over the weekend, my v-belt broke. Further inspection indicated that what might be an "auxiliary water pump" seized, thereby stopping the rotation of one of the 3 pulleys around which the v-belt travels and causing the friction that caused the belt to break. I'm not even 100% certain it is a...

Is the hose from the crankcase breather supposed to connect to anything? (On my motorcycle it routes back to the air filter; on others it has it's own filter and collector bottle.) On the parts schematic at Torresen Marine I see that the breather has an internal element. Does this element...
