Editing Ford small block engine (section)

===Marine 351===
From the late 1960s through the early to mid-1990s, the 351 Windsor had a long history of being [[marinized]] by Holman Moody Marine, Redline of Lewiston, ID (now defunct), Pleasure Craft Marine (PCM), and Indmar for use in several makes of recreational boat, including; Correct Craft, Ski Supreme, [[Hydrodyne]], MasterCraft, and Supra inboard competition ski boats. The early marinized engines were rated at {{cvt|220|hp|kW|0}}. Most PCM and Indmar marinized 351s were rated at {{cvt|240|hp|kW|0}}. In the early 1990s, a {{cvt|260|hp|kW|0}} version and a high-output version that used GT40 heads and the Holley 4160 marine carburetor was rated at {{cvt|285|hp|kW|0}}. A few 351 GT40/HO engines were marinized equipped with throttle-body fuel injection (TBI) and were rated at {{cvt|310|hp|kW|0}}. The marine industry's relationship with the 351W platform ended when Ford was unable or unwilling to compete with GM's production of TBI- and MPI-equipped engines in mass quantity. During that time, the recreational marine community's small-block V8 platform of choice shifted to the {{cvt|350|cuin|L|1}} [[Chevrolet small-block engine (first- and second-generation)|Chevrolet L31 (Vortec 5700)]] engine series.
