I am looking at replacement wheel cylinders for my boat trailer. I looks like there are two choices. Steel (cast iron), or aluminum. Which is better for a boat trailer application?

R, Steve

Aluminum is much better.

What I with them is rremove the dust boot and fill the area under the boot with OMC/Bombardier triple guard grease. Then I use high temp rtv to seal the boot to the wheel cylinder to keep out water. I also use a little rtv where the pushrod goes through the boot. The grease and rtv keeps out water and allows them to work longer without seizing. I also put a little grease on the metal piston, that's the part that seizes from corrosion.

Thanks Lou!

BTW, how long do they last when you prep them like that?

My boat sits on a mooring so the trailer doesn't have to go in salt water more than 4-6 times, I've had one last 6 years so far...
