Checked alternator and harmonic balancer both good.
Pumped out oil, took old filter apart and found no metal shavings, and yes there was some water in oil. I have learned all jet boats get water in the oil sooner or later.
Anyway, I filled a new filter up with oil put it on and filled the crankcase with good 10-40w oil took out the plugs cranked it over about twenty times, put plugs back in hooked it to water hose so I could run it longer I went to the right side of the engine and the noise was louder. I pulled the valve cover tappets were dry turned it over by hand and check for loose tappets none.
It seamed like they were to tight could not wiggle any of them.
Started motor with out valve cover and let run for seconds no oil.
I am thinking lifter or oil pump.
I live in N, E Oklahoma it got into and it got down to 0 a couple of times could that water in the oil have froze and broke lifter or oil pump.
I am going back out and pull the other valve cover, probably have to pull intake and the engine before it over, was hoping to start the summer a better.
Sorry for ramble any advice is appreciated.
