I scored a 7 on a par 4 today.
I was rusty....
First tee'd ball, drove into pond directly in front of tee.
Second re'teed and drove a hook into OB to the left.
Third retee drove the ball onto the green.
Is this a triple bogey?
Not for the shot into the water hazard. Most misunderstood rule in golf. Provisionals are for balls lost or out-of-bounds, not for balls known or virtually certain to be in a hazard.
But, it sounds like he observed his ball entering the hazard, and then going out of bounds. So there was no reason for a provisional in the second case either.
Why in the world would people who don't have the slightest idea of what the rules are answer a rules question and then excuse themselves by saying they aren't a rules expert? The situations in the OP's question do not require a rules expert. He got a 7. Yes you can re-tee a second, third, fourth time if the situation warrants it. You can re-tee your ball, of you choose, any time you hit into a water hazard off the tee. You can hit a provisional if you think the ball is OB (or lost, but that didn't come up in the OP) but NOT if you think the ball is lost in a water hazard. These are basic rules, and while it is OK to not know these things is it just weird to try to answer a rules question when you DON'T know these things.
You can't play a provisional if you ball is in a water hazard.
You must play another ball under penalty of one stroke using the provisions of Rule 26.
If your ball is OOB you must play another ball under Rule 27-1b with a penalty of one stroke.
