I've always used the "aqua-lube" strut bearings, they are what Dimarco used when my boat was new and they are what I use now. I get them thru Glen-L. If want the nitty-gritty scoop, call Ron Braaksma. He'll definately sell you the best one out there, whether it's Aqua-lube or not. His number is in the back of Hot Boat mag, and Drag Boat review. If you can't find it, let me know, I have it in my number book.
