Marine Repowers in El Cajon
Considering replacement power for your boat? Start with a conversation about your current engine, the boat itself and what you want from a repower. Our shop is in El Cajon and serves boat owners across San Diego County.

Start with your current setup
Tell us the boat year, make and model, your current engine make and model, and why you are considering replacement. An aging engine, recurring problems or a change in how you use the boat can lead to different questions. Include details about any previous engine work and the condition of the boat.
Explain what you want to improve
Describe how you use the boat and your priorities for replacement power. Reliability, maintenance and performance goals help frame the discussion. The engine is part of a larger system, so compatibility with your boat and existing equipment needs to be considered before selecting an option.
Repair, rebuild or replace?
If you have not identified the cause of a running problem, discuss engine diagnostics first. Thompson Speed and Marine also offers complete engines, long blocks and short blocks. Call with your engine information and goals to discuss which possibilities are relevant to your project.
Discuss your repower project
Send your boat and engine details through our service inquiry page or call (619) 784-3116. Let us know what you hope to achieve and any questions you have. We’ll discuss the next steps for evaluating the project at our El Cajon shop; call ahead before bringing your boat in.
