John Deere 4045

The 4.5L is a 4-cylinder marine engine offered in cold cooled or heat exchanger configurations, either non-cooled, naturally aspirated or turbocharged. It offers fewer external connections, reducing the number of hoses and accessories that can leak or break. The motor has a constant force up to 400 rpm below nominal speed, making these motors an excellent choice for launches, workboats, trawler yachts and patrol boats.
