Best Of

Today I figured out why my AC pump was leaking salt water into my bilge!  This is a 1" threaded pipe that corroded because they used brass instead of bronze.  Eventually, the pipe wall got so thin that water started spraying out through the threaded section.  Luckily, Nantucket has a really good hardware store that had one in stock.  Brass, but it'll work until I can get a bronze one.  

I'm kicking myself for not replacing the pipe when I replaced the pump three years ago!

Yeah mine came as a kit of all,

Just my opinion. But I would replace the switch as well as the circuit breaker at the same time. I think the one that has all that included is the better deal. Even if you decided not to replace it it's good to have those spares on hand just in case.

This year’s theme is for each boat to pick one of their favorite themes from all the Rinkervous.  This is year 20!

I replaced my 600 with the 1000 but had to add a relay and rewire.

Congrats -- awesome boat! 

You can definitely change the calibration point.  The exact button sequence depends on make and model ... download a user manual for yours and find the "programming mode" to change the temperature offset. 

Beyond that, it might depend on where the temperature sensor is mounted.  You'd have to trace the sensor cable -- a flat cable like an old-school phone cable.  Maybe you can relocate the sensor so it's seeing return air and not affected by the cold air coming out from the AC unit.  

Sorry for giving generic advice - others can give advice specific to your 390, but maybe this will get you started.

I swapped out for the 700. And wished I had done it years ago. It's pretty straightforward to get to you simply have to remove the mirror to get to the access hole for the chain. You also need long arms or a decent extension to get to the bottom of the bolts. The bolts all line up and the wiring calls for the same gauge wiring so it is a pretty straightforward replacement.
