I ve never really gotten much in mine ,but I would not run with out them ,Just wish they would keep the sand out of the block:( I have the hardin like Monstaa talked about just on my innercoolers and the gil on the motors came on the boat

Wish I had strainers in my '93 bravo/top gun last summer while running in a poker run on seneca lake (new york). Took in sea weed in stbd. motor oil cooler, just enough to notice "slight" reduction in water pressure, rise in water/oil temps. End result was 2 blown head gaskets from steam pockets forming in top corners of heads at #2 and #7 cylinders. strainers are going in now. Cig. owners manual says bravo equip set-ups don't require strainers ! I am amazed at what I have seen in strainers in other friends boats.

I knew I shouldn't have ask! lol - Now I am going to have to get strainers. Thanks Ted.

Strip, how do you like the clamps on GIL strainers? I'm thinking about getting one.
