420 DA Thread

I have been staring but can’t find how to turn spot light on and then toggle to rotate. I see under “lights” switch for “spot” but that didn’t turn it on.

You should have a black mouse looking thing with ACR written on it... That's 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.

A few years ago I ordered new props . I gave them my RPM , MPH at every 500 rpm. I gain 4 mph tru the entire spectrum. At 2350 I know cruise at 30 mph @ 40 gph .. its 80 % load which im told we can do all day long . Funny I top out at 35 mph , 2360 rpm . I don't recall the GPH but it was not pretty .

Does any one know where the shift control modules are located?

I am in the middle of a full electronics upgrade, including my Smartcraft DieselView and have spent a lot of quality time looking up under the dash and in all sorts of compartments around the helm!

On my boat (2007) the shift is full electronic, but the throttle is short cables to a set of modules located behind the small "chart pocket"/cup holder bin next to the helm seat. I suspect your shift is setup is either setup the same or you will find the shifter modules next to the throttles.
 
If you have replaced your tv in dropdown hatch in cabin with a smart tv can you tell me a bit about the process and what you used? I would like to replace with a smart tv.
 
I hate the mattress on our boat. For some reason it doesn't fit quite right in the base. It looks like the factory original mattress but it is a bit wider than it needs to be and climbs us the hull sides a bit towards the head. This causes it to cup at the outsides. Also, we added 2" of high-quality memory foam but that's just a patch for the problem of the poor quality underlying mattress.

So I'm considering having one made and would like to hear from any of you who've done this already. Our boats are a bit unique in that the cabin ceiling is so close to the top of the bed. If you put in a monster thick mattress then you're going to feel the loss of headroom.

I,m really leaning towards an inner-spring pillow-top design and not a solid foam product.

Questions:
1) what thickness did you select
2) Where did you buy it
3) About what was the cost
4) Did you have it made where the sides are angled to match the hull form.

That's it for now.

We bought ours from Tom Buis at www.beds4boats.com and it's great. Thickness is about 8" with the inner spring, and pillow top. I think it was about $2k with the options we chose. We went with he Huron model. If you look at their website I believe there's a pic of a 420 on there.

Yikes !!!... I replaced ours with foam... bought it at the foam Factory they have different densities. Then added a 2" memory foam on top.... thickness matched the original...I think all in with the Walmart electric knife was $375 and a couple hours work with a beer in my hand. It is the most comfortable bed we have ...I wouldn't dismiss foam right out of the gate.
 
Probably not directly relevant to you because I am in Australia, so more of an FYI, but I had a custom innerspring and pillowtop mattress made. They were available with 2 Spring heights. From memory mine has 6 inch springs (shorter of the 2 spring heights) with a 2 inch pillow top. Cost was circa A$1 boat dollar.

$2K isn't too bad if it means my wife is more comfortable and continues to enjoy coming up to the boat.

I hear you and live that life... I can't count the number of beds I have bought at home, the work house and the boat for that very reason.... Actually right now she is on about the house bed again... :)

JWILT purchased a new mattress but I don't know who from.
 
We previously had a 2007 310DA and then got out of larger boats once starting to have kids. Fast forward 7 years and we are now looking at selling out motorhome (have a 43 foot Class A) and get back into boating. We are looking at 380 & 420 DA’s, and leaning more towards the 420 to have 2 baths (since we are a family of 5).

Anything in particular we should be aware of or check out when narrowing down boats? It’ll probably be a 2004-2008.

Also we have homes in FL & Michigan on Lake Huron. My thought would be to have it transported beginning of summer & then in August back & forth so we can enjoy it in both places. Anyone ever done this? Any idea on cost or if it can even be done?

Thanks for any input!!
