Volvo Penta Water in pistons

Maddie · 08-01-2021, 12:42 PM

I have a 2017 Cobalt with 300HP Volvo Penta motor with 70 hours that has water in the pistons. I have been without the boat for 6 weeks while Volvo and the marina try to figure out how water got into the pistons. There are 2 other boats at the marina with the same issue. One is 2016 and other is 2019. I'm told there are many others throughout the country with the same issue. Volvo has no answer as to how the water is getting into the pistons and has decided to replace a bunch of parts in hopes of solving the issue. I was wondering if anyone has had or is having the same problem.
