Boat Repair in Dunnville, Ontario
Hartzel Marine is Dunnville's local boat repair shop, right on Broad St E. For most local boats we are a ten-minute trailer or a same-day drop-off, and the work gets done in a real bay with real tools, not a driveway guess.
Family-run since 2001 · Now in Dunnville, Ontario · Serving Haldimand, Norfolk & Niagara boaters

Dunnville boats split between the Grand River and the Lake Erie access at Port Maitland, and the two wear engines differently. River boats come in with fuel-system gunk and low-speed cooling issues; lake boats come in with water-pump impeller wear, overheats and charging trouble from long open-water runs. We diagnose first, write the estimate, then fix only what was agreed, and every job is logged against the hull so next season starts from what we already know.
What you get
- Full mechanical diagnostic
- Electrical and fuel system testing
- Cooling system pressure and flow checks
- Itemized written estimate before repair
- Photographic service record
- Outboard, sterndrive and inboard work
