Turn/Acceleration issues

[JB4times4]

So I recently got my boat out on the water for the first time this season, and I'm not sure if I'm expecting too much or if it is under-performing. Here are the two issues I'm encountering:
It seems to take a bit of time to accelerate to top speed, not a huge amount but about 10 seconds.
When I turn to sharp I lose all speed and have to accelerate again from basically a stop.

Anyone have any ideas? I have read that disabling the turning assist may help, but I have no idea how to do that.

Thanks for any help!

You have a cavitation issue. (probably)

BUT....... let me ask......


1) Are you talking about a "sharp turn"... or are you almost sliding the boat? (like I sharp skid)

2) If you push the throttle full... from a stop... are the engines reving up, and you aren't going? (like spinning your tires) or do the RPM's com up as the boat speeds up?

When I'm going at a decent speed and turn the boat more then about a 45 degree turn it drops down to ~10-15mph

2) If you push the throttle full... from a stop... are the engines reving up, and you aren't going? (like spinning your tires) or do the RPM's com up as the boat speeds up?

It feels a little like both, more the first rather then the second though.

cavatation........... replace your wear ring

I'll plan on that then.
Any suggestions on where to get the wear ring?
Anything else I should replace while replacing the wear ring?
Also, I saw this post on how to replace it http://www.seadooforum.com/showthread.php?20587-how-to-change-WEAR-RING&p=89611#post89611, is this the same process I will need to follow?
