Re: Please help me ID this 14ft speed boat
Can not tell you the model but I can say that that configuration hull was colloquially known as an "SK" type. They all had low freeboard, no windshields, long front decks, and there was a "bump-up" where the windshield would be. Back to back built in seating like yours was almost always used. Earlier models were flat bottom and later ones were vee bottom like yours. They were a "California type" hull used for water skiing and racing out there. Larger models with rear mounted custom dragster engines and Vee drives would do well over 125--and that was back in the 1970s.
Classic design ones were not square at the stern like yours: They were rounded at the transom from the splashwell to the chine--called "tumblehome" and the hull was almost teardrop shaped with the rear of the deck near the dashboard being the widest part of the hull by a wide margin. Wild custom colors were the standard with many metalflake finishes common, back when Candy Apple Red, Pearlescents, and Metalflakes were upscale paint jobs and George Barris was king of the automobile customizers.
