Narrative:

We just completed an air return from our first failed attempt into the island airport. We had returned to get fuel and try again once the weather passed. The weather had moved to the east of the field when we arrived and the conditions were VMC below 7;000 ft. The flight ran smoothly and we made a visual approach to the runway due to the winds being calm.once I reduced the power on the flare on landing; the right propeller stuck in low pitch and yawed the airplane to the right of the runway. The next obstacle was a giant line of standing water in the middle of the runway. The aircraft now hydroplaned further to the right. I used left rudder and the power levers to keep the aircraft on the runway. The #4 tire went into the grass for a brief period; which is when the right prop chopped up the weeds and sent them up the right wheel well. I quickly got the aircraft to the middle of the runway again before I completed the back taxi to the terminal area. No damage or injuries occurred to the aircraft; passengers or crew. I felt this all could have been avoided if the communication between dispatch and airport operations got all the weather information correct. I was never informed of any standing water when I departed. I was told the winds were calm so we choose the runway and was only told the runway was wet due to the storms that passed over the airport before we arrived. If I had known or could have seen the runway had [that much] standing water I would have never landed in the first place. Nothing can be done about the low pitch [problem which is a] maintenance issue; so I might have had a problem keeping the aircraft on the centerline; but the standing water made matters worse. The pilots need to have a better source of weather advisories and runway conditions in the future. The weather observer never reported the standing water because it was in the middle of the runway and not visible from where he stands to get the weather report. You would actually have to drive down the runway to get an exact reading on the runway conditions.

Title: A malfunctioning reverser; standing water on the runway and a possibly flawed field condition report combined to cause the right main landing gear of a Beech 1900 to briefly exit the hard surface on the landing roll.
