Boat Winterization in Dunnville
Dunnville boats winterize at Hartzel Marine every fall, right here on Broad St E. The process is the same on every boat for a reason: done properly, it's the difference between a $0 spring and a cracked block.

A wet, cold Dunnville winter is hard on a boat that wasn't put away right. Our package fogs the engine, runs antifreeze through the cooling system, stabilizes a full tank of fuel, changes lower-unit and engine fluids, and pulls the battery for storage. It's all logged against the boat, so the spring tune-up and the next winterization both start from a known history.
What you get
- Engine fogging (two- and four-stroke)
- Antifreeze through cooling system
- Lower-unit oil change
- Fuel stabilizer added to a full tank
- Battery disconnect and optional indoor storage
- Documented winterization record
