What We Service

Complete Winterization Of Every Water System

Michigan and Indiana winters are hard on a boat that has not been properly prepared. We winterize the engine and every water system on board so freeze damage does not turn into a spring repair bill.

This includes engine fogging and fuel stabilization, draining and treating raw water and fresh water systems, winterizing the head and holding tank plumbing, and running non toxic antifreeze through lines that could otherwise freeze and crack.

  • Engine fogging and fuel stabilization
  • Raw water system draining
  • Fresh water system winterization
  • Head and holding tank plumbing service
  • Antifreeze through all water lines
  • Battery and electrical check
