Questions on Marquis 59

Usually the 2 holding tanks have an equalization pipe so they act as one tank for pumpout and other reasons. Could be 2 totally seperate systems, but would be rare.

You should be able to run the entire panel off of one 50 amp cable if you don't run to many items (manage the load).

Quality is very average on Marquis.

One could be black water and one grey water. I'd recommend calling Marquis and seeing if they can shed light on it.

I helped a neighbor with one of these a few years back. Pretty good boat. From memory the two holding tanks aren't connected but if i remember correctly there is only one overboard discharge and have to flip a valve in th lazaret te which is a pita when underway. I could be wrong... check the specs and manual

I believe you can run the boat on one cord, if limiting your loads but never tried

May be a similar setup to my Carver--2x 50 amp shore power cords, and a whole separate panel for the second that powers only the 2 A/C units for the bridge and aft deck. No way to run everything off 1 cord as there are 2 separate panels.

Thx for your follow up.

I have a 2008 Marquis 59. Very happy with the boat.

The boat has two waste tank pump-outs on the stern. They are NOT connected. Everything said above is correct. The add-on crew cabin toilet (3rd toilet) is connected to the port tank.

With regard to AC and using a 50 amp splitter. I have not done this, but I believe the isolation/booster system that was used on later boats would prevent this from working.

If you have any additional questions, feel free to contact me. Best of luck.

Hi Scott, I am in contract on a 2008 59 Marquis Markham edition w the MTU Series 60 825 hp engines and have a few questions: 1. I have heard some owners have issues w their trim tabs, have you experienced any issues? Have you considered the Zip Wake system?
2. What kind of fuel burn are you getting at cruise, and what is your cruising speed?
3. How does the boat handle rough seas, and what is the worst wave height conditions you have experienced with your Marquis.
Thank you in advance.

I sold my Marquis in April.
Yes, the trim tabs are an issue and I would encourage you to include replacing them into your planned expenditures. I did not consider Zipwake, but think that would be a great addition. My boat had the Volvo D12-800's and it burned 50 gph at 20 knots, which was my cruising speed. That is fully loaded with fuel, water and stuff. I put over 1100 hours on the boat over 5 years and ran it through everything. It is a wet boat, but very capable and will not disappoint.

Scott, thank you for your prompt response, much appreciated. One last question: Have you had the boat on the ICW? If so was the draft of the vessel an issue transiting the ICW?

Draft should not be an issue on the ICW. Not for anything close to that size. The series 60's burn low 60's GPH at cruise rpm.

I ran it in various parts of the ICW between VA and FL. No issues.

Hello,

Do you still have your Marquis 59?
I just bought a 2008 Marquis and I have some questions?

Thanks for the reply.
The Grey water sump tank under the bed is not draining. I do not see a circuit for it on either panel. There is a circuit for the sump in the crew.
Have you had issues with this?

Rich

Thank you!
