I also just saw your post on the KPM ones.

Purple real nice...

You want stainless not aluminum. The salt water will eat that in no time.

Re: Seawater Strainers

im really happy with my kpms, they wont let a single grain of sand pass thru & easy to clean out. rm

Re: Seawater Strainers

I just bought a boat with a 525, not sure it has strainers in it, I will find out next Monday. How much are those you are showing in you Pics?

Re: Seawater Strainers

At least my drives are coated. The KPM strainers I have are raw and on there way to becoming dust. I've never seen anything disintegrate so fast.

Re: Seawater Strainers

Sounds like they didn't get anodized or there is some stray voltage at work

Re: Seawater Strainers

hi ;
The strainers are coated in 50 micron hardcoat to MIL spec. Please send these back for warranty. we will send you two new ones. We have about 900 of these units in the field , all over the world including the military and have never had a problem.
Could you please email. with your address and we will get some sent to you with immeadiate effect.
What concerns me is you say that they are not coated , and I trust your judgement on this. Two years ago we supplied 8 strainers to a customer who specified uncoated against our reccomendation. . If they are uncoated We can pin point where they come from. We now serial number every product and pump chamber to eliminate these problems .

With reference to Aluminium; in salt water, you are not wrong , but it only occures when a potential charge is set up(Galvanic Reaction) and the principle of nobility (dominant metal) . Hard coating is what we call a dielectric which means it does not carry a current, and this in turn stops corrosion. Put a multimeter on hardcoat and see if it works.

Aluminium alloys nowdays are very good and in the raw condition very close to admiralty brass. Thats why so many parts are now made in aluminium. I have seen stainless steel rust But lets face it Titanium is the best but who can afford it.

With the weather we have in england and wisconsin we know a lot about corrosion and that why all limeys look so pasty since we have no sun . We test all our products and competitors products in uk waters which are quite harsh . You would be amazed what we find.
