Why winterize?
Reasons to winterize your boat with Erwin Marine Sales:

  1. Unprotected engines can and will freeze causing cracked blocks and/or manifolds
  2. Erwin Marine has industry trained certified technicians that will service your boat so that you can be assured your boat will be ready to hit the water come spring!
  3. Winterization has changed due to E-10 Ethanol! Do not try this at home!
  4. Water can get trapped in blocks and freeze, even if it seems like they are drained (MPI engines require anti-freeze flushed through the modules)
  5. We offer special promotions that combine annual service requirements with winter protection
  6. We stand behind our winterization process & service work
  7. Piece of mind - 100% guarantee no freeze damage if winterization is performed by Erwin Marine Sales.
  8. Cheap insurance vs. high cost of component or engine replacement

Winterizing is an important part of boat ownership. Protect your investment. Schedule your appointment today!
