500/520 DB official thread

Does anyone have or use the Fly bridge Seating area converted to the lounge pad?
 
Anyone with pyrometers notice the harder you push, the lower the EGT's? If I run at 1700 RPM's, my temp on my starboard motor gets up to 1100 degrees. If I push up to 1950 rpm's, my temps go down to 950. Fuel burn goes up obviously.

Yup, that's why you need to pitch down to keep fuel burn @ 18-19 GPH in that 1950-2000 RPM range. One of my engines runs 900 and the other 950 degrees @ 1960, burning 19 GPH.
 
It's that cooler under the turbo - Cummins has a bulletin on the bracket and will provide the repair kit. The surveyor should know all about the issue; if not it's a good "test" to see if you have the right surveyor....

Actually the cooler is a separate issue from what I described and show on the picture but you are correct about the cooler bracket as well.
 
So to get the exhaust temperature we will need to add the sensor and gauge?

The Cummins Mercury Display does not show the exhaust temperature?

Thanks
 
3 seasons on my impellers and again they looked new this spring.

Owner said the same thing (QSM11) which I doubted until now.

What life span are you guys getting with the two 8D Batteries?

When you start the motors do you use the combiner each time to start? Owner told me it isn’t needed but it is better on the starters. However it still made the GPS flash/restart when he started the engines with the combiner engaged.

Thanks
Rich

My house batts lasted around 5-6 years and yes I always use the crossover when starting the engines even with new batts the engines don’t like to turn over slow i was told.
My routine is start the engines then start electronics so I don’t have them rebooting

Interesting, I didn’t know it is good practice to link them together for starts. I will start to do that.

Thanks joe, approx how many hours in those 3 seasons? I was planning on changing every other year but maybe I can go 3 years.

Have thought about doing this on our 420 as well since the grid heaters tends to drop the volts a bit. I usually wait 20 secs before cranking them over. Was wondering if combining them to start would be good practice.
 
I added 2 more 8Ds to double the amp hours. We anchor a lot, and with only 2 batteries, the voltage would drop below 12v overnight. They’re stacked in a custom rack aft of the waste tank.

I also added a dedicated battery to the generator.

You turn off the genny at night?
 
I am not sure if it effects 07s but my cabinets are delaminating on a lot of the edges. Mostly on the doors to the cabinets.
When you say delaminating of your cabinets do you mean cloudy finish or the peeling of the veneer? I have the cloudy finish of the doors in spots. My cabinetry seems to be holding up so far. Does anyone know of a refinishing shop or has anyone tried this themselves?
