Mid-season outboard work for the canal-corridor crowd is one of our regular jobs: a fouled water-pump impeller, a fuel-delivery problem, a charging fault, a lower unit that's taken a hit. We diagnose it properly, quote it in writing, and turn it around quickly when the parts are on the shelf. Repowers are part of the conversation too when an old engine is finally done.
What you get
- Powerhead diagnosis and repair
- Lower-unit service and seal replacement
- Impeller and water pump replacement
- Fuel system service and carburetor work
- Ignition and electrical repair
- Compression and leak-down testing
Why Hartzel for Welland
- 01 Canal and both lakes.
Welland boats run the rec canal and trailer to Erie at Port Colborne or Ontario at Port Dalhousie. We know the wear each one puts on an engine.
- 02 Repeat-customer shop.
A lot of Welland owners come back every season. We explain the job, price it in writing, and do not pad the bill.
- 03 Authorized Tohatsu dealer.
Factory-trained Tohatsu service and OEM parts, plus Mercury, Yamaha, Honda and Suzuki.
- 04 Leave it, we will call.
Most Welland owners drop the boat and we keep it for the work, then call when the estimate is ready.
- 05 Winterize and store.
Bundle fall winterization, shrink wrap and storage so the canal boat is sorted until spring.
