Online Marine Engine Mechanic Courses and Classes

Many marine engine mechanics take courses in internal combustion engines as part of automotive repair technician degree programs at the associate, bachelor's and master's degree levels. These automotive engine classes are then supplemented by taking one or more specialized marine mechanic classes. There are also a few online courses aimed specifically at marine engine mechanics.

Essential Information

Marine engine mechanics must have knowledge of engines, specialized marine fuel systems, marine electrical systems and marine propulsion systems. A student's foundational understanding of marine engines can be accomplished by taking automotive engine classes within associate, bachelor's and master's degree programs. Examples of relevant degree programs include an Associate in Science in Automotive Analysis and a master's degree in automotive engineering.

To further understand the specifics of marine engines, a student can take individual classes in watercraft design, marine electrical systems and marine propellers. Significant time is usually spent studying manufacturer engine manuals specific to various engine types. It is difficult to obtain a thorough understanding of marine engine mechanics through home-based study alone.

Online Marine Engine Mechanics Courses

  • Engine Repair Course: Students study engine configurations, engine cycle fuels and oxidizers, combustion chambers, air inlet systems, valves, crankshafts, flywheels and measures of engine performance.
  • Introduction to Watercraft Electrical Systems Course: Students learn terminology, theory and practical knowledge regarding marine electrical systems. The purpose of this course is to teach students the theoretical knowledge involved in designing and maintaining marine electrical systems. Curriculum introduces students to the concept of 12-volt DC marine electrical systems, including their design, specification, and installation. Other topics include basic electrical theory, wire sizing, marine electrical components, circuit protection and installation procedures.
  • Propeller Selection for Boats and Ships Course: Students explore the anatomy of the propeller; from physical and hydrodynamic characteristics to cavitations and hull effects. Students learn to review resistance calculations, inspect trial data and analyze vibration. Students are expected to be able to select appropriate propellers for various hullforms. Surface piercing propellers and jet skis are also studied.
  • Beginning Marine Design Course: This course focuses on hull design, simple chine hull and complex sailing schooner hull. Students learn to model a complete hull, deck and superstructures. Marine design terminology is also studied, including relevant terms like port, starboard, forward, aft, inboard, outboard, stem, forefoot, keel and skeg.
  • Outboard Engine Technician 1: Students learn basic procedures for working on outboard motors. Topics include rigging outboard systems, diagnosing fuel problems, lubricating outboards, inspection procedures, running wiring and control systems, and basic troubleshooting. Instruction for using specialized tools for outboard repair is also included.
