Narrative:

Upon preflighting and reviewing [the] logbook we discovered that the auto pressurization was deferred along with a maximum fuel load. Our first concern was with passenger comfort due to a flight in manual pressurization. I spoke with owner services and my partner spoke with the owners; who were already on site about the issue. The owners were insistent on taking the plane; in its current condition; and did not to be delayed any further. But this did not solve the fuel weight issue.after double checking the performance numbers for the flight; I confirmed that we were over maximum ramp weight and maximum takeoff weight with six passengers and maximum fuel. The aircraft was at 19222 lbs; the max ramp weight is 18497 lbs; the max takeoff weight is 18397 lbs. At this time my partner was inside the FBO speaking with the owners and a [company] representative trying to find a good solution to our issues. I called the acp (assistant chief pilot) to inform the company of the weight issue. I stated that we are over maximum ramp and takeoff weight with 6 passengers. The acp started that he has been working with my partner of the issue for an hour and that we are okay for takeoff and would just need to burn the gas in route to our destination. I again stated that we were over maximum ramp and takeoff weight and asked how could we take off in that condition. Again the acp stated that we can take off; but would need to burn the fuel in the air. Feeling that. Was getting nowhere in the conversation; I ended the call. I then sent an email to the company stating that the aircraft was over maximum ramp and takeoff weight (19222 lbs) and attached a picture of the limitation from the fom. After my partner returned from seeing to the owner's needs; I informed him about the weight issue also. He then called and informed the company that we would not be doing this trip. In the end; the company was able to accommodate the owners with [another aircraft] that was onsite with no furthering delays.the main reason for this report the pushback I received from the acp concerning a limitation on the aircraft. Namely the maximum ramp and takeoff weights. It might be a good procedure for acp to reference the limitations section of the aom when something like this happens in the future. The issue of manual pressurization with owners on board; this should never be done in my opinion. During [another flight] there were times when the cabin pressure was climbing or descending at 3000 fpm! As the pilot monitoring during this leg; it was all that I could do to keep the cabin pressure under control in moderate turbulence; heavy rain; and dealing with two reroutes. I was definitely tasked overloaded. If I also had to deal with passengers during this time; I feel that there would have been a safety of flight issue. Not to mention the substandard owner experience.
