When out the other day after cleaning the shafts/props the boat wouldn't exceed around 15.5K (up from 12.4 prior to cleaning) but it would do any better and it never "flattened out." I thought I had the Tabs on full down.

This AM I was thinking about why it wouldn't cleanly plane and I checked to find that the TTs werent' working and that they has stayed full up. Then I remembered that a few weeks ago I was working in the the aft section of the boat under the queen and had turned off the circuit breaker to the tabs. So that resolved the why they weren't working issue but it got me wondering about if a 53 can plane properly without the tabs full down.

Anybody's able to do so?
