Ontario Crank Service

We took our Donzi to O.C.S. for service as it was under performing, heavy vibration at take off and difficulty getting on plane. Heath was helpful with the diagnosis and water testing when our usual marina wouldn’t address the concern.
The repairs took longer than expected, but we wanted the job done right. To his defence it was a very busy time of year when we brought the boat in.
The boat is perfect and we are happy with the performance, it now planes well and is good for pulling people on the tube.
We would recommend OCS for marine repairs.

I had OCS rebuild a crankshaft from an old 91 Polaris Indy Trail 488 fanner! It had smoked a rod bearing on the stator side of the engine. I also had OCS bore the cylinders out .060 oversize. The crankshaft was a work of art!!
I finally rebuilt the engine and it runs fantastic!
Well done guys!!

Chris has always given good advice and provided quality work on the 15 and counting engine blocks I have sent for boring and sleeving.

Brought in a bad crank and Chris looked after me. He had the crank rebuilt with a very short turn around. Also bought a cylinder from them quick they had in stock. Only reason they got 4 stars is because the cylinder had to go back to cv tech for a plating warranty issue and it took a while but that's more on cvtech and the shipping than ocs. If you have a 2 stroke with a bad crank, come and see these guys.
