No need for a fin. Especially on a one engine. Just remember the main thrust of a jet boat - no power no control. Try it before without for awhile. You will learn how easy these things are to steer.

I would add…

Practice, Practice, Practice.

Go out on a calm day in an area where you have room and mess around with it, learn how it feels, and get to know what it is going to do. Fins or not, a side wind, or a rear quartering wind will be the biggest challenge.

Well you have a lot of replies, I had three yamaha jet boats and put thrust vectors on them they definitely help at low speeds. Good luck with your new boat.

You also have the blow out plug so you really should add an EZ lock to it to avoid a serious issue if it blows out during use. I designed these years ago at the request of Yamaha jet boat owners having issues with the plugs blowing out very inexpensive insurance against a plug blow out, time tested and proven just like my steering and remember I am not a vendor I am an inventor, I only sell what I invent and I did the steering 21 years ago . You can believe the inventor and specialist or not it's up to you but this will be a very interesting learning experience .

You gotta love a gal that knows how to drive like a boss!

Love me some Detroit diesel..

Love me some 71 series... lol slam you thumb in the door and drive it like ya stole it... Ive got a 72 GMC C-60 NAPCO 4X6 project that i put an 8V-71 Detroit in and a RTO-9513 in it (that I did a homebrew Double O).. 11R22.5 rubber and a airshift 1187 Transfer case with a 0.75 OD so i can spin the 7.20:1 axles fast enough...
