The best way to solve the problem is to remove the DLE get a rope Tie it to your Boat and use it for an anchor Spend a few dollars more and buy a DA I went that same route with motors and were always working on them or sending thjem back. Wised up bought a DA-100 put it on my Cap-580 never touched anything 4yrs. later 3rd flip and it is off to the races.
For a few dollars more an excellent and reliable motor pulling your airplane with no problem.
