Last year when hauling the boat for the first since purchase I found one of my trim cylinders failed. The ram broke right in the middle of the plastic cylinder body. We replaced the cylinder and put the boat back in the water. After a month or so another cylinder broke. Again, it was a similar failure where the plastic cylinder body broke. Thinking the cylinders were just old we replaced all four and went on with the season. We recently hauled the boat for winter storage and upgrades and found one of the new cylinders installed had failed some time during the season. Any idea why these would continue to fail? They are Bennett cylinders and each trim tab has two cylinders. The boat is a 54' Donzi Sportfish. I'm not aware of hitting anything and the tab itself shows no sign of impact. Does anyone know if you can get cylinders that are not plastic? Perhaps aluminum or stainless bodies?
