420/44 DB Owners Club

I was having the same problem trying to read the switch legend and I liked your switches so much I had to do the same.

This is my goal! I contacted the company via email and they sent me back what appears to be a complicated switch diagram. I suspect its not that complicated though. I cant imagine how we can simply replace the switch cover to get this result and not the whole switch?? The diagram includes phrases like "add additional wire" "daisy chain them together". Any help will be appreciated....
 
Does anyone know the socket size to fit the coupling end shaft nut?
The one inside the transmission coupling, it looks to be around 2-1/4" AF

I don’t have answer to your question but can you post picture of what the i side of that coupler looks like and another after you take it apart? I’ve not seen one and I’m curious.
Also, anyone know if I can separate the couplers and slide shaft back enough without removing prop to pull the coupler off shaft so I can put new and spare dripless seals, and can this be done while boat is in the water?
 
I’m sure it’s posted but I’m not locating it- can someone tell me about fluid quantities? Looking to do my first servicing now that temps are cooling off here in northern FL.
How many qts or gallons of oil for the 8.3 mechanical’s?
How about the generator oil?
How many qts for the ZF’s?

Antifreeze quantity per engine and for geny?

Thank you
 
If you go to Seaboard marine you will find all the cummins info you need. Large parts supply also
Coolant 30.5 QTS
Oil 14-18 QTS
Transmission 4 QTS
Hope this helps
 
Good sign for me if we go the route of the 42 is there are now a very few with listing prices under 300k. Much better than the 315-350 I've been seeing.

The coupling can come off without removing the prop, the coupling is 165mm long & the clearance from prop to rudder is more than 200mm (250mm from memory)
Just preparing for the job when I next haul out, but I'll post some pics when I get the couplings off.

Thanks for the info. What makes for such a big spread on the oil quantity?

Man that is a lot of coolant, 15+ gallons! lol. Plus however much more the gen uses...

Yep, they use a lot of fluid. Each engine needs almost 6 gals of Valvoline Blue oil and around 6 gal of coolant, I use premixed Cummins 50/50. If you get 12 gal of oil and and 13 gal of coolant you'll have enough to do the generator too.
 
Might be silly question but how often should the coolant be changed I've never thought about it
 
Someone ask for a picture of the teak tables we use, here is one.

It was me. Thanks. I’m still looking into the options out there and especially looking forward to the next big boatshow to see what the industry has on offer

Sorry @AEO I could not remember sir, but we have two of those and they work great for us.

I changed my QSC's over to CAT EL, always has been a good product for me and easy to purchase.

Good question, in the Great Lakes more than 5 or 6 years is not uncommon. Depends on usage, but as Mark.60 said, test strips are the best indicators and use the Fleet Guard premixed.
 
Everything I can find says our transom has no wood, can anyone here confirm that the transom on a 07 44 sedan is solid fiberglass with no wood where the hydraulic swim platform is bolted to the boat.

My understanding also it there is no wood in the transom and that it is solid glass. When I had mine out of the water for my grounding repair in 2016 I had the opportunity to replace the hardware on trim tabs. some had broken off the heads so I had to grind out the old screws and repack the holes with marine tex. There was no wood present. That was an 06 44 and am sure the 07 would be the same. Is there a reason to be concerned? Is the hydraulic platform hardware loose and leaking?

5 years from the time of replacement. It's recommended to test your coolant annually to determine if you need to change filters.
