Chrysler 30 Marine Engine: A Reliable Inboard Propulsion Solution The Chrysler 30 is a compact, gasoline-powered inboard marine engine engineered for dependable boat propulsion in recreational and auxiliary applications. Produced by Chrysler in 1973, this legacy powerplant delivers straightforward mechanical performance, making it a timeless choice for enthusiasts restoring classic vessels or seeking robust, no-frills operation on the water. Key technical specifications underscore its efficient design: an inboard configuration with a displacement of 491 cm³ (approximately 30 cubic inches), generating 30 horsepower (22 kW) at the crankshaft. It runs on standard gasoline fuel and features a manual start system, eschewing complex electronics for inherent simplicity. With no specified cylinder count in available records, its single-unit architecture emphasizes a lightweight footprint, ideal for space-constrained hull integrations. Aspiration and ignition details align with era-appropriate carbureted systems, ensuring compatibility with OEM parts from Chrysler’s 30 HP outboard lineage for maintenance ease. In marine environments, the Chrysler 30 excels through its marine-specific benefits, including exceptional reliability derived from manual cranking that mitigates electrical failures in saltwater conditions. Its inboard mounting enhances vessel stability and maneuverability by providing direct drive to the propeller shaft, reducing vibration and improving handling in choppy waters. Chrysler’s renowned durability—rooted in automotive-grade components—offers longevity with routine upkeep, while gasoline fueling provides cost-effective operation compared to diesel alternatives of the period. Performance characteristics highlight its nimble responsiveness: the modest 30 hp output suits moderate speeds, with high-RPM gasoline combustion enabling quick acceleration for activities like waterskiing or short-haul cruising. However, its smaller displacement may yield higher fuel consumption at full throttle, limiting extended range without careful throttle management. Ideally suited for medium-sized recreational boats, dinghies, tenders, or as auxiliary power in larger craft, the Chrysler 30 thrives in niche applications such as classic boat restorations, racing auxiliaries, or backup propulsion where mechanical robustness trumps modern efficiency. Though it may require periodic rebuilds to comply with contemporary emissions standards, this engine embodies enduring marine utility, blending simplicity with proven seaworthiness for discerning skippers.
