JLM 3.29

JLM marine power latest generation PERKINS based marine diesel engine. The base engine is built for industrial application and adjusted for marine use in the most difficult working conditions, which guarantees reliability and long duration. We achieved visibility and simple and cost efficient maintenance with intelligent construction and high quality.

Indirect engine cooling system (coolant liquid cooling in the heat exchanger using seawater), guarantees optimal work temperature in all working conditions. Due to its low weight, minimal noise and vibration level and its compact size it is ideal for installation on sailboats, recreation, work and fishing boats. The new generation of JLM marine engines comply with strict exhaust gas emission laws around the world (EU Stage IIIB and US EPA Tier 4).

Info: “JLM marine power”: standard 24 month warranty proves our quality, durability and reliability.
