I have developed a very strange ill handling problem.
Specs: Wellcaft twin 260 Alpha 1's, w/tie bar, w/Bennetts. 19 x 21 3 blade.
First, she's NOT porpoising. At speed (on plane), above 35 mph the boat wants to suddenly dart left and dance to the right. Mostly dart sharp left. Almost to scary to handle, feels like I'm loosing control. The only thing I can do is back down to recover the steering.:nono:
Also, at that time (35+ mph), it almost seems like she's is running at an 11 o'clock angle (left to right). I have tabs up or set to the level the boat for people weight. Trim tabs adj. does not seem to matter in the squirliness of the ride.
One thing I did do was add skeg guards since my skegs were whittled down to damn near nothing. Could this be a problem? (I know I can remove them to check, but perhaps someone has an answer.) Stern drive alignment, toe-in /out? Prop Cavitation? Uneven trim? How accurate are the trim guages? Gimbals? Bad angle on skegs?
Any one had this problem?

Thanks for the responses. Steering cable I believe is OK. No slop any time. Gimbals I'll check this week. (too hot now) What bothers me is that this just started this last week-end, prior WOT runs were fine.
 
I had that a year ago. It was a power steering pump with junk in it. Very dangerous situation and usually only did it at upper rpms. Had to pull back quick but easy to regain power steering. I almost lost it a couple times. Took all the fun out of boating for a while.

I can see where that is also a possibility. I almost lost it a couple of times too....
I'm still hoping for a spun prop. Just too hot to work on it, even my son told me "go get scr***d"! :mad:

Well, looks like a spun Prop hub. I have the Alpha I and
the original SS Mirage Prop, not the Plus. I can not seem to find just the delrin hub insert anywhere. I don't need the whole kit kabudle, brass insert splines and washers are fine. I can't seem to get on the MercuryStore web site.
I have a 25 ton press. I am assuming I can press the old/new, out/in myself rather then send the prop out for 2 weeks. Correct? Comments?
Anyone have another good source for the hub insert, I'm in the boonies.
