Engine Re-Powers

Breathe new life into your boat with a brand-new engine. Today's engines are leaps and bounds ahead of their predecessors, offering cutting-edge technology that enhances acceleration, power, and responsiveness. But the benefits don't stop there.

Imagine reducing your running costs and enjoying more uptime on the water. A new boat engine can make that dream a reality. You'll not only save money with improved fuel efficiency but also minimize your environmental footprint compared to engines designed a decade ago.

The advantages extend to onboard electronics and controls. With new boat engines compatible with modern equipment like multi-function displays or electronic control units, you're set for a seamless integration. The result? A vastly improved boating experience that's not just more enjoyable but also more cost-efficient.

Investing in a new engine means less money spent on maintenance in the long run, more time enjoying the open water, and a boat that's ready to meet the future head-on.

Engine Diagnostics

Take control of your boat's health with Volvo Penta VODIA and Yanmar LUNA, two innovative tools that bring diagnosis and service to your fingertips.

Volvo Penta VODIA resembles a handheld computer, boasting an intuitive design that makes it incredibly user-friendly. It's more than a tool; it's your personal mechanic, providing data and results from tests, fault detection, diagnoses, and more. All this information is presented in easy-to-understand text and clear graphics, extracted directly from your engine. But that's not all. VODIA also gives you the power to adjust numerous engine parameters, putting control back in your hands.

On the other hand, Yanmar LUNA, available on select Yanmar machines, serves as your virtual co-pilot, providing real-time information that offers an unprecedented level of remote insight into your vessel. Stay updated on engine RPM, function setting status, error status, fuel consumption, and operating hours. With Yanmar LUNA, you're always in the loop.

These advanced tools are revolutionizing boat maintenance, making it easier and more efficient than ever.

Pre-Mechanical Inspections

All potential new boat owners should have a pre-purchase mechanical inspection performed prior to purchasing a new or used vessel. It is critically important to look at factors other than the price of the vessel. We can help you with our technical expertise and knowledge in evaluating the mechanical integrity of your new purchase.

    • A Testament to Yanmar!

      This Scimitar just got a major upgrade! We've recently fitted it with a brand-new exhaust system, complete with new turbochargers for the Yanmar 4JH3E-DTE engine. The original parts held their own for nearly two decades - a testament to Yanmar's superior quality OEM parts. Yanmar truly stands for durability and long-lasting performance.

    • Volvo Penta DP Sterndrives

      This Mustang recently made contact with the ground, causing the lower shafts to be sheared and the propellers to be lost simultaneously! It was time to rejuvenate this vessel and replace the lower leg assemblies & new Duo Propellers!
      Plus an application of Propspeed is a fantastic choice for all marine applications!

    • No More Electrolysis

      This Coral Coast experienced an unfortunate encounter with electroysis, resulting in the gradual deterioration of the propellers. Thanks to the dedication of the team at RL Marine in welding/tuning the propellers and the diligent efforts of Josh, the vessel was successfully re-launched just in time for a memorable Christmas Day on the water.

    2023 Repower Highlight

    This Noosacat received an early birthday present. It has been upgraded with a stunning pair of twin Volvo Penta D6-320s with the latest DPI Sterndrives, replacing the previous KAD42 engines. This new powerhouse can reach a speed of 30 knots when running at WOT 3600rpm. The owner is extremely pleased with the performance it produces, and the paramount importance of having a reliable and safe vessel for his family cannot be overstated.

    A big thank you goes out to everyone involved for making this repower seamless.

    • The Mechanic - Josh

      Often found in the bilge, in the boatyard or anywhere there is an engine, Josh is the founder of Cap Coast Marine and is the heart and soul behind the operation.

    • The Assistant - Kelly

      Either parts interpreting, passing Josh spanners, selling parts in the shop or booking new jobs in. Kelly is the technical side of Cap Coast Marine.

    • The Manager - Turbo

      Often found sleeping on the job or requesting attention from customers. He is definately the cutest member of the team.
      **woof** - Sorry Josh
