410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread**

I got the stainless exhaust elbow off yesterday to gain access to the water heater/battery area. This is my first time dealing with this but it looks like there is some damage to the fiberglass exhaust pipe. Does this look bad? What’s the fix here? Fiberglass repair? or cut off a few inches and replace with a longer exhaust hose?

Its starting to to delaminate and crack, so maybe a good idea to replace. I think this is just 6" marine fiberglass exhaust pipe...standard stuff.

Centek Vernatube Hi-Temp Fiberglass Marine Exhaust Tubing

Centek elbows are made from the same corrosion resistant high-temperature resin used in Vernatube and allow for change in direction in limited spaces where exhaust hose might buckle and resist flow. Precise outer diameters allow for easy connections. Feat

Measure, and buy what you need. You can paint if you like.

And the rubber couplers / clamps. The couplers are probably blistered inside.
Regarding paint - use a good epoxy. Otherwise the couplers will become one with the hard pipe.
 
Thanks for the suggestions! This is my first diesel boat. Just got it late last year. Working on getting a good baseline. Coolant has been flushed and raw water system has been serviced. Cleaning engines and bilge now. Fuel system is coming up next! I'll look into the options for replacing the fiberglass pipe as well. The hose couplers are in pretty good shape, no delaminating. Wondering if they've been replaced at some point.
 
subscribe to the site and look at Franks diesel treatment - I went from black racors to clean red fuel in one shock treatment when I did the same thing on our boat. Takes you a few changes of the racors to clean out all the dead algae
 
Hi Everyone

Does anyone know if the bow thruster batteries get charged by alternators also or only from the battery charger during shore or generator power

Our factory install is from the dedicated battery charger. I always have that breaker on whether on shore or Gen power
 
Can anyone tell me where the wire from the accessory switch on the dash goes? It does not seem to do anything, and I would like to use it to power some electronics

Mine powers my autopilot. Does yours have a wire coming from it currently? If so you may have to trace the wire to be certain of the current setup.

What I found is the wire from unused switches is cut and wrapped in the harness somewhere under the helm.

Thanks. Mine has a power wire coming out of it, but doesn't appear to control anything. Might very well be wrapped in the harness. Now to find it and repurpose it to on/off my NMEA network..
 
Took off the switch panel (12 screws) and saw there were two outgoing wires.Nothing happened when I switched it on. Was able to trace one of the to a disconnected wire and will use that
 
FWD & AFT thrusters here on a 450DA installed by PO about 12 years ago - (have receipts for $29,000 ! ! !)

Fwd thruster has two dedicated group 24 batteries operating off their own independent charger.

Aft thruster runs off one set of the factory engine room batteries.

Regarding the electronics, I added a BLUE SEAS flip circuit breaker and ran 8 or 10 gauge (don't recall which)wire to the helm electronics switch to power all onboard electronics.

The beauty of doing this is no more electronics reset during engine starts.

I did the same with the sound system and amplifiers, and also ran a similar system, breaker and wiring.

Mounted the breakers on the engine room fwd bulkhead.

Now that I'm close to the finish line I'd bet there is close to 100 lbs more wiring on her than when she left the factory.

BEST !

Replaced 4 of my 5 batteries yesterday (left the generator). Man...I'm sore. I'm getting tool old for this crap.

Boats launching everywhere! I guess I need to wrap up this waxing thing eventually.
