The hull weighs about 4600 pounds without engines. YThe weight of the motors are about 470 pounds per motor ( not including the props and assuming 6 cyl models) Note that just have a decent amount of gas in the tank will add 6 ponds per gallon. Water added about 8.3 lbs per gallon.
I don't know the pulpit weight but if you need to get that accurate I worry you are not sizing with a reasonable margin.
If you are trying to determine if a vehicle rated for a 5,000 trailer load, the answer is no. The trailer alone will weigh 1200 pounds and up depending on type and configuration.
