Novice back for advise! I have had 2001 Outback for the past three years. During the past month, when we make moderate to tight turns, we lose much more speed than usual.
- RPMs drop off a little.
-Increasing throttle in the turn does not help.
-Performance is fine when running straight.
-The prop does not have any damage and does not seem to be loose.
-Only dumb thing I did lately was leave the gas cap off when running the both for about 30 minutes.

Suggestions? Well, other than making sure the gas cap is on.....
