So after removing my motor from my boat and completely tearing it down (not a good end to the season) I find that the block is filled with sand. And by filled I mean allot 16lbs. to be exact. Anyone else encountered this and does anyone run a filter on the water supply from the jet??? I have a panther jet powered by a 460, any tips aside from the obvious "dont drive over sand"; this is definetly years of sand abuse especially since I only drove the boat 3 times before blowing it up due to overheating and running lean.

most likely sitting on the beach running the motor sucking up sand or in shallow water

The first time I took apart my motor, I had found the same thing.... the motor didn't ever over heat or anything, but it had a large beach in the block and heads.
I don't run anything to filter sand still, but I'm alot more aware in starting it in shallow waters. Up here I don't think sand is an issue, but down in Martinez where everything is sand it happens over time

Yeah thanks, I have pretty much figured out how it happened. ::)
I am just wondering if anyone else has the same issue and what if anything is anyone doing to prevent it. I am certain this is from the previous owner(s) not being careful about where they drove the boat and maybe not flushing it out properly. This condition also ruined a set of Dove-C heads.

If you have big wads of cash laying around, you could get a sea strainer. :screwy:
But I saw awhile back someone had a strainer from McMaster Carr that they installed, and they even posted the part #, I'm wanting to say it was TJS, but not one hundred percent on that. It uses a fine wire mesh to filter out all the sediment from the water, and probably even gets more than a sea strainer would. I'll try to find it for you.

Found it, here's the link to the thread.

Or here's the bit of information that really matters and the picture.
"Here is the part number and I used the mesh screen for it. Sorry I stand corrected it is good for 150psi.
