Top Fuel hydro ain't cheap!

All in the cost of owning a 4K boat.. want to race or sport run on the cheap.. a twin is not it.. want to own, race and play with a twin.. they know the score.

Cheaper than drugs, same high and legal

Charles Perdue · Oct 7, 2020

Compared to women...as for the high, I will leave that part open....as far as legal, sometimes.... but women are much, much more expensive

Especially if we are comparing twins to twins

Just could not resist the temptation...

Mark, in this video, the 1395's, or the 'other'?....

Did you break the motors in a single hydro first? or on a stand ?

Your twin still sounded a little "off" in the video.. like one motor was a little richer than the other. Never really cleaned out...

So many things to adjust on a twin,,,
I found it easier to run each motor in my single 90 hydro untill they were broke in,,, was a lot simpler that way.

It looks good, keep after it !

Hello It has the gas pipes on it this was the first time the boat was out in probably 15 years so still have to tune on it more the motors are running rich plus I had no needle in it for the water control so that has been added. Thank you folks for looking and have a great holiday.

Still cheaper than a family of 4 going out for dinner, to put it in perspective.

It cheaper then Almost anything else. A pro sporting event, golf, a
Real boat. And dinner for 2 and a movie. $100 isn’t anything anymore.
