The lineage of the Marlin can be traced back to the PBM-4 Mariner design proposal of 1941.The PBM-1/2, ordered in 1937, was fitted with Wright Aeronautical Company (WAC) 1,600 HP R-2600-6 engines. Follow-on PBM-3, -3C, -3R and -3S models were equipped with WAC 1,700 HP R-2600-12 engines. The final version of the series, the PBM -3D, had WAC 1,900 HP R-2600-22 engines. Even with the 1,900 HP engines, the PBM-3 series Mariner was seriously under-pow¬ered, with poor take-off, climb and single-engine performance.
