Handling at WOT problem
 

I own a powerplay xlt with a 406 with 450hp, at WOT throttle Ive noticed the boat leans kinda to the port side and the bow is kinda point it downward. Its VERY hard to keep it from flipping over almost. This starts to happen around 65-67 mph and after that I can no longer handle it. I still have more throttle to give it but it just becomes a nightmare to handle. I am trimmed out properly and the weight distribution seems to be right. Kinda clueless with this, Im running a alpha SS and a tempest plus 23p and problem actually gets worst with a few more people in the boat and I only keep about 10 gallons of fuel on board. Can anyone help me with this issue?

How deep is your drive sitting ? it could be installed too low ,so that the anti ventilation plate above the prop is getting full water.
This plate should be aprox 1/2 inch or so above the lowest point of the bottem (plate level with bottem )

My 22' with a 500EFI has significant torque steer to port until I trim it up. As I speed up and trim up the torque steer factor goes away. I'm running a Mirage+ which gives me quite a bit of bow lift. Maybe try a different prop to get more bow lift. Could the Tempest be giving you stern lift? I didn't think this was a stern lift prop.

I was under the impression that the tempest plus was a bow lifter, even more then a mirage plus was. I havent tried any other props of yet... just got this motor in the boat not too long ago. I do noitce when its doing the port side pointing downward thing that I am counter steering big time...

Did you just buy this boat or is this Chris?

I bought this boat in the winter of last year... I dont know who chris is... It came with a stock 350 and before it never did this...

pic of the boat would help.

Sounds like you aren't trimmed high enough causing bow steer and torque roll. What happens when you trim it higher?

I guess I havent tried to trim it out more, I'll give it a try this weekend and see how it goes... Should I be looking for some trim tabs?

Im not a full member so I can post pics, but this link takes you to the boat I own...

Trim it up more!

Be nice if it was a bravo you could swap a left hand prop and counter act the torque lean. My baja did this as did my buddies carrera.

put a straight edge on the last 6 or 8 feet of the bottom of the boat and check for any hooks in the hull if you have a hook it will act like a trim tab being down and make the boat lean to one side and it will get worse the faster you go

Are you out on Cass Lake? If so maybe I can help. I'm the guy with the White Cat with twin weed wackers... Bill

I bet if you trim it out more it will bring the bow up and ride much better. I had a boat that needed a lot of positive trim, even at cruise or it would lean badly to the left and ride like chit.

Like said try a little more trim or give another wheel a try. Possibly a 4 blade bravo. My 202 stinger seemed to run the best with a bravo prop vs the others i tried.

I am going to do all of above... I have a ballistic lined up to try and Ill also try trimming it some more. I also will try the straight edge thing tonight when I get home. But I boat all over pretty much... Union, Cass, Oakland lake... I'm all over the place.

I saw another powerplay on walled lake earlier this year with an open bow which Ive never seen before and it sounded like it had a BB in it and last year I saw another XLT on Woodland lake in Brighton. Kinda surprised how many there are in this area.

No hooks or anything on the hull... straight as an arrow.
