I have never owned a performance boat before. I got my new zx250 last week. went out tonight for first trip after getting break in done. It won't stop porpoising. If you are running on a smooth surface and trim up more than a 1/4 it starts porpoising. I am not sure if weight distribution is the problem or what.
Any advice would be greatly appreciated.

Break in should have shown you at what speed it comes on plane and when it falls off. If you did initial break in properly and ran with no trim applied, you should have found that you can run up to a pretty decent speed and not have to trim at all. So when it starts to porpoise you have too much trim for the given speed. You either need to speed up or trim down to match speed with trim.

Take a few minutes and run the boat from 1-3k rpms. Run about 60 seconds at each interval and slowly increase 100 rpms at a time. Run up to 3k and then back down again, 100 rpms at a time. This is how I was told to do my first 2 hours of break in and the entire time I was thinking what a great tool it would be for a first time Skeeter owner.

When you need to come off plane, keep rpm's up and reduce trim. As you feel speed slow down you can reduce throttle. You will learn to set it down and never porpoise.

I was told to do the entire break in time with the motor trimmed all the way down. I did that. tonight I was able to run it like I wanted too. So right now top speed without porpoising is 44 mile an hour. something seems wrong to me. I am talking about running across the lake. Not porpoising when slowing down.

Call the dealer you bought it from.

You say it's your first high performance boat and we all know Skeeters are trim sensitive. I wouldn't start adjusting anything. Just give yourself some seat time and each time it starts to porpoise, either put your foot in it, trim down a little, or do both till it stops.

And yes, call your dealer. Either your sales man can help or put you in touch with someone who will spend some time with you to help

The skeeter I traded in had a 115 two stroke and the same gear in the same boxes. You could run it wide open trim up and get top speed and never ever porpoised. That is why this one puzzles me as to why it porpoised if you trim up at all at any speed on plane.

I would bet you're not running with the hot foot pegged. (You should be). During the rest of your 10 hour break in you should run it HARD! Control speed with trim and not throttle. You want the engine hot to seat the rings correctly. When you vary your rpms every few minutes just use trim to do so.

It will be hard to make it porpoise if your foot is buried in the throttle.

I have an older ZX that never chine walked, soaked you coming off plane or porpoises at any speed or trim..... Based on some responses it sounds like the newer hulls porpoise? A buddy of mine had a hull on a cudy cabin that porpoised at 30-40. You could drive through it but in chop it would beat you to death between the waves and porpoising. Point is conditions may not always allow you to drive through it. I would have the setup checked out as it should not porpoise at all. Did you test drive one before you bought? And run it at all speeds? If you did and that one didn't then check setup and loading of weight.

I'm currently in the first Skeeter I've ever owned. You can watch Skeeters all across the lake porpoising. It's the thing I dislike most about my boat. I've learned to drive it properly but it was never an issue with the Ranger or Stratos I owned. As long as I'm driving it with the hot foot pegged I can trim it high and roll. If I want to cruise 40 or below, I have to lower the trim way down. I tell people it likes to go fast. :-)

Don't even try to pull a tube around at 20 mph. I tried and looked like one of those wake/surf boats with the nose high plowing down the lake.

Of course, there could be something wrong with the motor height as well and might need to be tweaked??? Let us know what you find out.

No I didn't test drive one. I had my older skeeter and loved it. I new the new one would drive different, but this one is frustrating to drive. It runs smooth with the trim all the way down, but you can't trim up at any speed on plane. The more trim you put into it the worse it gets. I tried throttling through it, but that's a no go. It just gets worse. I thought maybe my gear was too nose heavy. But it is the same gear in the same locations as my old boat. Its just kinda weird how it acts. Sorta feels like the nose is always falling down even at 5000 rpms. you get it up on plane and then when you try to trim up even a little in starts dropping the nose. The jackplate has not been messed with since I picked it up. Guess I will have to get the dealer to take a ride with me.

Just got my new ZX250 broken in a few months ago. I came out of a Nitro Z7 and I must say the ZX is very trim sensitive compared to the Nitro.

I am not expert by any means but I am not sure it is weight distribution as much as it is proper trim.

I have never driven a boat that seems as trim sensitive as the ZX.

Call your dealer but keep playing with the trim at all speeds and I bet you will get it figured out...took me a while but I did.

I am hoping to take it out again tomorrow and spend some more time with it. If I can't get it figured out then I guess its dealer time.

How smooth is yours when its in gear at idle. Mine is rough enough that the access panel under the dash vibrates. Is isn't near as smooth as my 2008 115 two stroke.
