Just bought new fixer-upper made by performer boat company in 1973. Hull is great except transom , had twin 170b volvo I/o removed for bracket and outboards has typical rot in transom easily repairable on this style transom. Never heard of boat manufacturer and would like to know if anyone has heard of them. Hull is copy of formula 233c or predecessor of it? Anyone got any suggestions on sizes of economical outboard(s) thanks for help
