420 DA Thread

The 42/44 is well known for water leaks over the gen. Look carefully at the pan under the generator and you will find it is either rusted or it has been replaced. I found water leaked through the cockpit shower and followed the hose right over to to the generator.
As far as new parts, some were available , you would need to call or plan on having a new panel made.

I removed the cockpit shower and covered the opening only after the damage was done.

Since were talking about water leaks . I have water in the stern rope locker. My line that's are hung are soaked after it rains . Also if I lift the engine hatch I have water that drips on the port side of the hatch that lines up perfectly with my port engine belt cover.... The seat is directly above . WTF >>>
 
Guys - I am replacing both the cabin refrigerator and my cockpit refrigerator in my 2006 44 DA. If you have replaced yours I'd like to hear what you chose and if you like it? For the cabin I was told either the Isotherm Cruise 130 or Vitrifrigo C130. I also want to be able to use the mahogany panel from existing frig to keep the color match. For cockpit I was told either the Isotherm Cruise 65 or Vitrifrigo C62ix. Open to other options that you may have used too.
Thanks - Mark
 
On the refrigerator I put a Vitrifrigo in my 340 it was awesome. This Dometic in my 44 is horrible.
 
So I got my pocket door for the aft cabin off. One of the rollers on top was bent and I was able to find that online.

But the guide pin on the bottom is more difficult. Anyone know a part number on these or know where to get them?

It is the spring loaded pin on the bottom of the door.

I know I bought some of those, but now I can't find the part#. I got them from my local sea ray dealer, may try them - my local dealer is very good at finding parts that are not well labeled in the parts manual.
 
Well we finally settled on our new to us 2006 44. Boat and engine and oil surveys/samples came back great. She needs some attention here and there to finally make her ours but we are glad to be back boating again. We spent the weekend mostly cleaning and moving in. The heat was unbearable but we managed. Also, a big thanks to FrankW who took time to review the results of some of the surveys for me and provide us with his feedback. Looking forward to this group and learning as much as I can, and contributing too..

Beautiful Boat! Congrats. Be sure to stay up on your raw water maintenance (aftercoolers). These are great boats. I've been doing most of my routine maintenance myself. Reach out if you have any questions.

I'm having trouble with the gel coat chipping in the bilge in the engine room. I think others have mentioned this on the forum. I don't want the expense or effort to replace the gelcoat so I started experimenting with paint colors. I found the Rustoleum Almond spray paint is almost a pefect match. I cleaned the areas that had the chipping and sprayed them with the rustoleum and the engine room looks new again. It was completed in less than an hour and the paint has proven to be extremely durable. I hope this helps others that hate the look of the missing gel coat.

Did you scuff up the area or just wipe it down with acetone to prep?
 
Guys - what is the sweet RPM for cruising? I'm trying to ramp up my knowledge on Diesel engines and heard of over revving, or too much RPM? I wanna make sure I am not cruising at too high RPM and causing damage. What is the high end? Also, I have heard the term "engine runaway".. Whereby we are in a full speed run.. Why does that happen and if it happens how do you stop it?

Congrats on the new boat!

You should check your RPM and fuel flow at a few points. For long engine life you should be at or under the rating curve, which for you engine would be the numbers below (these come from the sbmar.com website - fantastic support for Cummins Engines). In addition your WOT rpm should be well above 2300, 2365 is the max and you should be able to hit that and be at or under 95% load. If your WOT is under 2365 and/or fuel flow is higher at any of the points below you should consider dropping pitch or reducing cupping. Once your fuel flow is within that range you don't want to exceed more than 80% engine load for extended periods of time. Guessing 80% load is around 2450 rpms which will get you probably around 26 kts. We generally run closer to 2300 rpms, well under 70% load at about 23 kts.

Cummins Specs
RPM Gal\Hr
2600 25.4
2400 20.1
2200 15.7
2000 12.2
1800 9.4
1600 7
1400 5
1200 3.3
1000 2.1
800 1.3

Engine runaway is possible with diesels but not electronic controlled ones like the QSC we have as far as I know. From my understanding once a full mechanical diesel starts it no longer needs any electricity, just fuel and air, the only way to shut it down is kill the fuel or starve it of air. If an injector sticks the engine can run faster, pump more fuel and run faster etc until something goes boom or you shut off fuel or air.

Good luck and enjoy the boat, were on our 4th season with ours and LOVE IT.
