Issue we are having is boat is going slower at faster rpms. Normally top speed is at 27 mph on a 22ft. Party barge with a 115 mercury outboard. Wondering if water in one of the toons could be the issue. Left hand side seems to be lower than the right side.

Increased drag from increased weight can cause that symptom. It sounds like you have an idea of the cause. It's time to pull it out and check for water in the log.

welcome aboard

I agree, pull it and check for water.

most of the time, the toon logs crack at the top where the M brackets are.

Thanks for your input. I hope this is what the problem is

It has a little bit of growth, but not much. The toons were cleaned last season.

I cleaned my pontoons this spring before the boat got put in Here it is august and the toons need cleaning again, stuff accumulates fast and does cause drag.

My toon speed dropped from 21 to 14. Went to local sandbar to scotbrite the dirty toons. NOT the problem, rope wrapped around prop. No power T&T on my 1975 Blue Band.

One guy had a tree branch lodged ahead of the motor, causing a lot of drag and stirring up the water in front of the prop.....
