ZF Repropulsion – Our Marine Repower Process

  • Even better than before.

A marine repower is more than just replacing the engine. Our repower is also reassessing your complete propulsion system, including your transmission, propellers and controls. A decision to replace or rebuild. A renewal of movement…cruising along like before. Or even better than before.

It’s time to rethink the marine repower process. It’s really a repropulsion.

ZF Repropulsion. Propel ahead.

Questions to Ask Yourself About Repower

Do you love your current boat?

Build, handling, fishability, cruisability, etc. may be reasons to keep your current hull and begin a repower.

Do you trust the current engine / propulsion system?

Reliability and trust in engine performance should be the number one priority when making decisions about the propulsion system of your boat.

Has there been recent mechanical failure within the propulsion system?

A recent mechanical failure may be an indication of more to come and can also be a good time to replace the units instead of paying more money to fix the failure.

Have you considered the cost effectiveness?

A  marine repower is costly but can be well worth the investment. Take time to consider the costs before taking up this project.

Have you considered the time investment?

A repower may take a considerable amount of time, make sure to consider the timing of a repower, and determine whether you have a busy fishing “season”. If you do, then consider a repower during the slower season.

Where would a repower take place?

You want to choose a reliable marina and boatyard that has the equipment and resources available to complete the project. Cost of the time for the dry storage during the repower should also be considered.
