Engine Seized ??? Please help with Diagnosis
So I'm buzzing along about 3/4 throttle on Saturday..
Engine just stopped. No warning beeps or anything.
Thought dess key pulled out, but no.
All electrical looks fine. No Start/ No Crank. Can hear
starter engaging, but not turning engine.
Home now. Pulled plugs - no crank. Pulled Pump - No Crank.
Will turn over about 2-3 timing chain teeth at a time.
Chain looks intact. All rocker arms moving up and down- albeit slowly\ due
to cranking only a little at a time.
Was water in spark plugs holes/ on pistons, probably due to towing thru
rough water 10 miles.
Oil looks normal.. no water in it.
Oil Filter Pleats have a copper/brass fine metal particles in them..
Not a shitload, but enough to notice easily when you spread the pleats out.
Can some one please point me in the right direction of diagnosis

I got head off.
looked at pistions, walls etc...
Everything "looks" perfect.
Was able to finally get starter to turn over engine at a decent pace.
Was holding timing chain top part with screwdriver shaft, it was spinning nicely around
it flinging oil and all. Filter housing filling with oil, etc.
Then it just seized in place. I can't turn engine either way..
The timing chain looks like it jumped forward off the sprocket on crank and is
wedged between the block and ????
Anyone have suggestions or help for me...
Still don't know what caused the sudden engine stop and no re-crank

The engine was spinning really well with the starter before
I somehow let the timing chain get wedged...
Would it still spin like that with a siezed rod/main bearing??
And would that explain the copper/brass colored small particles in the oil filter pleats.?
Would taking off the PTO housing gain me access to the timing chain gears???
That way I could get that part straight and see if motor will still spin OK
