newbie/ need info on 92 180 nitro w/ 92 evinrude

[sailors hornpipe]

just bought a 1992 fish and ski 180 nitro tracker w/ 1992 150 hp johnson evinrude- havent got in the water yet- but cant wait - motor is good and runs great but i wonder if anyone out there has the same boat or simular? need to know the weight of the motor - im trying to figure out the max weight allowed in the boat - the info plate is so faded it is as if some one completely erased the info- i found a formula given by the us coast guard and did the equation and came up with 1260 lbs but this is to include the weight of the motor and all gear onboard-also wondering how it handles at high speed for tubing and skiing and just any good info - have to put in an impeller and do basic maintenance plus get paperwork together so it will take a little time to get out there - till then ill be dreaming of getting on the water!
