It's in my boat.

I have a Cruisair heating/air conditioning unit. It's tripping the circuit breaker and the copper pipe I am pointing to in the picture is getting almost too hot to touch. Any ideas on what could be the problem?

Thanks for all the valuable input. I've traced the wiring and have not yet found any corrosion of bad connectors. The one thing I haven't been able to find is the breaker between the motor (the lift is electric, not hydraulic). Anyone know where I should look?

It's a swim platform lift, model 5220.

2017 400 Sundancer. Bought brand new in 2018. Never had a problem with the electric swim platform until a couple of months ago, when the fuse (10 amp) started blowing. So far put in a new circuit board ($950) which seemed to help for a few times of using the lift. But then started blowing fuses...

I'm getting a low oil pressure signal on my Cat 3116 starboard engine and it's shutting down my engine. I know it's not the sensor because I swapped the sensor with my port engine and I still got it on the starboard. Also, I know I don't have low oil pressure because I clear the alarm and...

Today I finally fixed the problem (original topic of this thread). It was the o-ring on the pressure switch.

I know this is an old thread, but do you have the part number for the oil sending unit?

Has anyone who owns an older 400 Sundancer had problems with the carpet in the aft cabin getting wet/stained? I've had this problem for a while, and can not figure our where the moisture is coming from. I was just wondering if anyone else had experienced this and be able to trace where it's...

Anybody know the Sealand toilet model # for a 1997 400 Sundancer? I'm trying to buy the gasket for the toilet, but can't find the model #.

Well it's not the duckbills :( Replaced the 4 duckbills and re-installed the vacu-flush. Nothing's changed, bowl holds water, and pump cycles but never shuts off. I'm getting a vacuum at the bowl, when I flush it I can hear the vacuum/suction. Any ideas??

found the 4th duckbill imbedded in the pump

I took the whole pump and couplings out of the boat and took it apart on my work bench. I only found 3 duckbills.

I only found 3, 2 on the intake and 1 on the output side.

Yes the water remains in the bowl.

Back to my favorite forum for help with another problem with my 1997 400 Sundancer. I turn on the breaker for my rear head and I can hear the vacuum pump running for a few seconds and then it shuts off, everything working fine. I turn on the breaker for my forward head, and the vacuum pump never...

I called them Monday morning and they were at my boat Tuesday @ 9am. They had a big job scheduled nearby, but the boat is still on the east coast, so I got that spot. I'm having them change all the hoses, and with the new impellers, I should be good to go for awhile.

"This part I'm not sure on since I haven't removed our injectors but -- it's possible the overhead and injection timing dimension need to be adjusted now that the injectors are re-installed. Do you know if the mechanic did that?" This was not done, but I did notice the mechanic numbered each...

Mechanic figured it out! He took the injectors out and scoped the piston, no water/anti-freeze. Pressure tested the cooling system and nothing leaked into the cylinders, had a small leak in the hose connected to the thermostat housing. Put the engine back together and did a test ride. Discovered...

Good advice, I have a mechanic coming tomorrow morning.
