In an earlier post I asked about anchoring near brush piles. Clearly the consensus is "don't!" And thanks Ken Gaby for the detailed explanation why.
Maybe the reason I've been thinking I need to anchor is because my TM isn't running right? It's a Motorguide Brute 767, 12/24 - probably the original on my 2001 G3 18-ft aluminum. Even on 24 volts it doesn't take a whole lot of wind to send me to the cockpit because it won't pull the boat directly into the wind at all. And in calm water, it's not moving the boat as fast as a smaller 12V unit I had on a Bass Tracker years ago. The motor on this rig is heavy, I suppose: a four-stroke (4 carb) Yamaha 100, but something doesn't seem right.
Do TMs lose power as they get old? Batteries are definitely good. Nothing stuck in prop.
