420/44 DB Owners Club

Got a call from my neighbor today while I was at work telling me that a loud alarm was going off on my 2006 44. I checked the security camera, and sure enough a very loud, almost like a commercial smoke alarm or burglar alarm was going off. My neighbor went down to the boat and checked everything and nothing looked amiss. I had him turn off the battery switches and then back on, and the alarm quit and has not come back on. Any ideas what this alarm was and what triggered it? I am completely baffled!

The system monitor alarm at the helm can decide to go audible for no reason at all. I've had mine go off just by working on wires under the helm near it. It's also gone off on occasion when using the vhf mic which is right next to it. Sometimes it scrambles the two line display. Cycling power to it always gets it back to a known working state. I think its firmware may not be the most robust software in the world (just a theory).

Bill, thank you, at least that gives me some comfort that there is not a major problem that I am not seeing. I have never had a boat with that load of an audible alarm that the neighbors could hear it!

Hey Rob,
The high water alarm is fairly loud buzzer. If the second (higher) bilge pump in the aft of the engine room activates there is an alarm at the helm. I'm not sure if it goes off also with the forward engine room bilge pump and/or the galley bilge pump.

If it was that alarm I'm not saying your boat is sinking, or even if that pump activated! It could be a faulty float switch...

That's the same alarm as the system monitor alarm. System monitor detects and alarms for both high water pump and emergency forward bilge pump. Like Rob said, sounds like a smoke alarm. It's really fun when it goes off right next to your ear when you are working under the helm.
 
Well, definitely leaning toward faulty as I crawled all over the boat, and in the boat, and everything was bone dry. No recurrence of the alarm today. Definitely a loud alarm!
 
Another topic on the 44 SB. I just purchased my "new to me" 2006 Sedan with 700 hours on the Cummins QSC500s. The boat was winterized in 2018 with all the oils and filters changed. Last year, 2019, the boat was recommissioned but was run only 3 hours. When they winterized the boat last year, they did not change the oil and filters due to the low hours on the oil. So my question is, should i change oil and filters now, and then again in October/November, or just wait until I winterize? I don't expect to put a lot of hours on the motors this year due to work and river conditions, but I also don't like the idea of two year old oil in the engines, even though it appears very clean. Love to hear opinions on this.

Finally can post we will be proud owners of a 2005 420DB. We should close on it next Thursday. Big change from the Ocean we are moving from. I have read through the thread, more than once probably, and I have learned so much already. Thanks for all the insight that you guys have provided. It made making the choice easy.

Rob, I am not a boat expert. But oil with 3 hours and u just ran it ~275 miles, any condensation should be gone. Look at dip sticks . If appears normal in my opinion you good.
My farm tractors I do the same way.

I second that Rob, enjoy your boat while you can and just do the annual service when you put her away for her long winters nap. There will be plenty of other things to obsess about the rest of the season;)

Thanks Roger and Rusty, you guys gave me some comfort in waiting! Now if we could just get a day without rain to boat!

Does anyone else have flaking paint on the aluminum frame on the bridge windshield. If so has anyone tackled refinishing?

Yep, I've got a few areas that are bubbling up. Its been that way ever since I bought the boat five years ago. It has not spread noticeably so I have not tackled it. Grinding away the paint and surface corrosion wont be hard but spot painting will be very difficult to match I fear hence I live with it. If anyone has a good matching product to top coat the area with, That would be a great share.

I did mine last year and removed the TV to get more room to work. You can also removed the small locker in the cockpit to give easier access to the hoses.
When you get the old unit out be sure to check the condensate drain as mine was plugged and caused so much rust the base was almost gone. This unit drains all the way forward to the shower sump in the stateroom area!
Before I installed the TV I glued on some insulation over the air gaps in the hole cut to give access from the cockpit locker. I thought it would be better to air condition interior air instead of hot humid Florida air from outside.
Since it's gotten pretty quiet here, I'll dredge up the air conditioning thread again... just now spending some quality time on our newly acquired 420 and devoured this entire forum (thank you Alex) before making the purchase. A few newbie questions:
1. The condensation drip pan in the salon was nearly full after running for a week in 80-90 degree temps, and I suspect the condensate line is plugged somewhere along it's long trip to the forward sump. Forward staterrom drip tray is bone dry and AC working well in both locations. Any tips on how to unpclog the salon line? I simply wet-vac'd the water out as a temporary measure. Somewhat rusty but not as far gone as the pics Alex showed earlier in this thread. Pic below showing water about 1/4" from the top of the tray.

2. I'm looking to replace this metal trim at the edge of the galley but don't know what the part is called and haven't had any luck searching for it. Anyone out there sourced a replacement at some point?

As for the metal trim, why not take some acetone and remove the adhesive residue and then all good? There is a white anti-skid piece of tape there from the factory and yours is missing leaving the residue. As for the plugged line, I would start with some low pressure compressed air and increase pressure to see if I could remove the clog.

BJ - I got a 25' snake from "China" Freight and ran it down my lines. Unblocked them nicely. BMAC on the 58 Sedan Bridge Official Thread got half inch nipples and 5/8" clear hose with a garden hose adapter and said a lot of crap came out when he flushed the lines out.
 
After a week trip in the boat I decided to give the engine room a good cleaning. I was wiping down the stbd motor when I noticed some slowly leaking oil behind the throttle linkage. See pictures below. It looks like the oil is coming from the plate that is secure by 2 torx screws. Anyone know what this apparent cover is and if there is a gasket back there that just needs replacing? I haven't dove in and started removing parts to get at it yet.

Another new to me boat question. What are the 3 thru holes forward of the bilge pump in the attached picture? I think the one on the left is the Raymarine transducer. Not sure on the others.
Dont mind the grime, that area is spic and span now.

Great suggestions, thank you Bennett and Carter. I'll check out the 58 thread too and report back on how it goes.

It's an adjustment housing cover. Cover is removed to make adjustments to the fuel system.
There would be a gasket of some type, possibly an o-ring.

The drain hose makes several bends coming out of the pan and is probably where your clog is. I tried a snake but wound up cutting the hose open to remove. Once you get it open you can flush it into the sump until it is clear.
