"ok. a while back we had water

"ok. a while back we had water in the gas tank and cause a valve to stick open. we had the head repaired with 2 new valves and all new valve guides. Tuppens Marine was the place we took the boat to for diagnostics and fixing. before we knew what the problem was, we would take the boat out and run just fine and slow speeds and idle great. going WOT was very rough until it planed out and then would just cruise as if nothing was wrong at all. after we got it fixed(btw one cylinder had 0 compression due to the stuck valve) we ran it on the water with an external tank of fresh fuel and ran GREAT for about 30 min. on the way back it was kinda shaking a bit more than normal. last time we took it out, it had no power at all and surged really bad. really really bad. we changed the plugs and tried again and ran great till about 26 mph and then steadly lost power and speed. after that it was runing rough again and wouldnt WOT. what can be happing? someone please help}}"
 
"Sure would be nice to know wh

"Sure would be nice to know which model Four Stroke you are speaking of. If it's an injected engine, water in the fuel will not stick a valve."
 
"its a 2004 150hp F150TLRC 4 s

"its a 2004 150hp F150TLRC 4 stroke. my dad and i took the fuel rail off and sprayed the injectors with some carb cleaner, put fresh plugs in and now it works very nicely. lets hope it keeps up. now im thinking that tuppens really screwed us over"
 
Water through an injecor wont

Water through an injecor wont bend a valve there isnt enough volume at worst it might raise the compression slightly.

Cars ran water injection without bent valves.
If the engine gets a guts full of water through being sumerged while its running it may hydraulic and bend a conrod.

Do the math on this...a v6 running at 5500rpm how much air does it comsume per minute and then if 1\10 of 1 percent was water droplets how much water gets sucked through the engine?

You will be very suprised
