We stand behind our work!
All of our service work is guaranteed against defects in our workmanship or the quality parts that we use.  Ask us for details on your repairs.

The short version is:
From tune-ups to complete rebuilds,  we can fix it.

Check your drain plug before launching.  We often remove them when boats are in for service.
We have invested in computer diagnostic systems the last few years in order to keep up with the times.  We proudly use the M.E.D.S. system from CDI.  This allows us to help diagnose and fix issues with newer outboard engines, I/O engines and Jetskis.
Get a M.E.D.S. Report on your engine today.
Looking at a used outboard?  Why not get a MEDS report to help you decide?  The report shows many useful items such as:
Hours used
Rpm ranges during those hours
Historical Fault data
Current Fault data

Let us help you make the right engine choice.
