Like so many others I'm looking for info on my old Grumman Sport Boat, serial # 1404-G-158. Primarily I'm interested in year of manufacture and load capacities for this vintage. She's in excellent condition- no dents, dings or repairs. Along with a vintage 6 HP Johnson, it's the perfect fishing boat for our north Maine woods lakes an ponds. At 112 pounds my wife and I can load it onto our camper with little trouble and you never know it's there. Thanks in advance for any info.
