are the strainer/filters a good thing?
I have a buddy that keeps talking about a strainer he just purchased to put in his cooling hose. I guess it keeps from sucking sand and crap into the engine cooling system. Do these things work and do they reduce performance in any way? I can't see how they would reduce performance but are there any cons for putting one in?

I had two strainers, one on the engine cooling line and one on a dedicated line I installed which feeds my aftermarket intercooler.
Engine cooling line strainer had issues with airlocks & overheat warnings after prolonged idles in no-wake zones. I believe I had that strainer installed too high in the hull and could have addressed it by repositioning low in the hull, in line with the pump outlet line. At the time, I just opted to delete it. I did retain the IC strainer since the flush procedure is more involved for that component, it's not critical at idle and that strainer had never caused problems.
Per post #2: If you want the added protection a strainer offers, carry a spare strainer cup and O-ring to be on the safe side.

I'm glad this got posted. I was about to order one of those since I've started riding on the shallow river. I'll just stay away from the shallow parts.

I think i will do the same avoid the strainer and try to avoid sandbars.

I also run a strainer. When ever I clean the strainer I have never seen anything in there that would not pass straight through the intercooler. I am thinking of getting rid of it also.

I don't see a reason to use one on the engine cooling side. Any trash small enough to get through the strainer on the pump should go right through without clogging anything. I often ride in rivers where there's lots of crap in the water & have never had an issue. There's also no need for one with a stock IC. The water passages in the core are very large & pretty much impossible to clog. I installed a Groco on mine when I upgraded my IC. So far so good after about 40 hrs, but after reading about problems others have had with them I started carrying a straight 1/2" barbed fitting in my toolkit so I can quickly bypass the strainer if it breaks.
