i was did several WOT shutoffs on mine this summer to do some plug checks. kill the key, then shift it to neutral while the motor is spinning down the boat will still be on plane when you already have it in neutral so the water pumps stop.

my biggest concern at first was water coming right up and over the swim platform onto the engine hatch, turns out i got no more water on my swim paltform than any other time i come to a stop. pull all the plugs and no water to be seen and able to get a great plug check.

I'm sure not all boats will react the same as to how the water come up behind them so it may be best to do your first test without actually turning the motor off so that you know the tailpipes are not gonna take a gulp of water. also in my case i have internal flappers in the tailpipes going through the transom so i know mine wouldnt take a gulp of water no matter how hard the wake came at it.

A better way to prevent water from coming up the tailpipes is to make a turn right before you completely come off plane, basically slow down in a circle. Most of the wake will hit you from the side instead of straight up the back.

But a few seconds of idle time wont kill a plug reading either.

if the bow drop and hooks you could ruin a good pair of underware !!

Slowing down too quick can be real dangerous. They get a little squirly and want to go sideways.

I prefer the a/f meter. The rest is just guessing.

i prefer a/f ,pyro's , and reading the plugs .... makes for no melted pistons

waayyy too fancy for us normal folk....

You A Listers get all the cool toys


Oh, and Dave, you better bring your A game the next time we run. Ran 97.3mph on Wednesday....

Phil,

You ran that number to impress your Mom ! Don't try that everyday.

I find killing power at WOT is to risky, at least in my little hull.

I believe only what I see, and you can count on the A game next go around Phil. If you really saw that much of an increase you need to take some jet out in season, you are way rich. Put a bung in the exhaust and you can use my a/f meter if you like.
