THANKS - the current problem is the REMOVAL OF THIS YELLOW BEAST !
View attachment 147647
Pulling on it in all directions - appears to be fastened from the bottom, and I can see what appears to be a screw in the left foot closest to the front.
Found only one screw from below - in the cabinet beneath the microwave:
View attachment 147644
there are no other fasteners accessible from below the unit.
Removed the door and every screw to the left side:

Removed the screws holding the middle shelf from the next cabinet over:

At this moment, there are zero visible screws to remove.
I can usually figure this stuff out, but am now at a stopping point.
PLEASE HELP ! ! !

Replaced.
Had some issues locating a similar sized unit that was available to ship.
Came up with this:
Amazon.com: Panasonic Microwave Oven NN-SD372S Stainless Steel Countertop/Built-In with Inverter Technology and Genius Sensor, 0.8 Cu. Ft, 950W : Home & Kitchen
it's the one pictured aways back

Can either of you post a pic with the new microwave installed? Mine works but its ugly. What did you do with the coffee maker? Find anything to fit there by the steps?remove the plastic feet
screw through the panel, into the base of the new microwave.
use the shortest possible screws as to lessen the chances of doing any damage to anything.

*Looks good! My factory coffee maker just stopped working.
Has anyone replaced their forward ac unit? Mine is a cruise air 10k btu. I had to rebuild the pan a few years ago and now this season it has stopped working. I replaced a few fuses in the electrical box and it kicked on for a moment, the. Shut off. The new fuses were still good… looking at a Webasto unit from citi marine. Anyone have a replacement unit that worked for them?

When I initially lowered the selling price on my 10 meter Trojan International, I swapped out some high end equipment with the Sea Ray.
In 2013 I removed the Trojan's VDO tachs and installed a Floscan system set up for the Yanmar 6LP intercooled/turbocharged diesel engines consisting of flow sensors for supply and return on both engines and digital tachometers that also recorded constant GPH, total gallons burned per engine <resettable> and with an interface to NEMA 0183, to provide an instant NMPG total number.
This setup requires an initial calibration and a second calibration after burning off some fuel. Further fine tuning of the calibrations can be done, albeit with diminishing returns, as the first calibration creates tremendous accuracy.
I have completed the first calibration and now have some initial data to share which will be refined as I have more information.
While results on the identical hulls/prop set-ups may vary, here are some takeaways for THIS particular vessel and props:
A 76 NM run fully loaded trip leg yielded a total average .705 nmpg running between 2200-2400 RPM
- Of note: this boat may weigh in heavier than most 450's as it is equipped with both bow & stern thrusters and two additional Optima batteries forward. Additionally this boat has an unexpectedly heavy vinyl plank flooring, a good deal of non-factory wiring, some of which is high amperage and we generally run with full fridges and carry numerous tools, spares and gear. We'll have a good travel lift weight number at the next bottom job haulout.
- Boat has clean bottom & props and makes 2800 rpm.
- Props are 22x22.5
- Tabs are employed/adjusted/applied in this perlim data to gain the best speed/efficiencies
- The 450DA hull is in fact very load sensitive. Burning off 1/4 to 1/3 of the fuel load combined with 50% fresh water carried on board results in a 12% increase in efficiency.
- As fuel burns off and efficiencies increase, so does speed at a given RPM
- Higher RPM rates (at least with fuller tankage) are more efficient than lower RPM rates
- preliminary fuel burn is consistently higher than the published CAT table.
FULLY LOADED
2000 RPM @ 16 kts burns 11.5 GPH - CAT data shows 7.5 GPH
2100 RPM @ 17 kts burns 12.3 GPH - CAT data shows 8.8 GPH
Burn off 80 gallons:
2100 RPM @ 18 kts yields .77 nmpg
2200 RPM @ 20 kts yields .78 nmpg
Burn off about 125 gallons of fuel and get into some no wind, smooth as glass water shows some interesting results:
2300 RPM @ 23 kts yields .83 nmpg
2400 RPM @ 25.5 kts yields .89 nmpg
converting that last 2400 number to statute miles is a shock:
29.34 statute miles per hour
1.024 miles per gallon
these numbers began to drop significantly, as sea conditions became choppy.
I'll be sharing more data as it comes available.
BEST !
