Outboard engine troubles

Current Location:  Lana's Cove mooring, Cayo de Luis Pena (off west coast of Culebra), Puerto Rico
Miles Traveled:  0
Weather:  Mostly sunny, light winds, hot, occasional showers, low-80s
Highlights: Hot night at anchor last night (almost zero breeze through the boat), and eventually surrendered to the heat and turned on the generator and A/C for a few hours.  Planned to take the dinghy into town this morning to fill up the propane tanks, but outboard motor was sputtering and stalling on us.  Terry cleaned and lubricated the engine and changed the spark plugs, which helped some, but still needs some work.  We're pretty sure that all of these issues resulted from when we overturned the dinghy and dunked the motor last May in Culebrita with Jim and Donia.  Guess we'll have to find someone in St. Thomas that knows more than we do about fixing outboards.  Until then we'll have to minimize our use of the dinghy, and break out the oars as necessary!
