Needless to say, I was quite skeptical until I mounted this unique motor on my 8' Walker Bay RIB for a test ride up and down the creek behind my house. It weighs in at only 25 pounds for the motor and the battery pack - easily handled even by the young (my 10-year old grandson) and the infirm (yours truly). There are three speed settings: maximum, fixed time, and max range. My Garmin handheld GPS clocked average speeds at 4.1, 3.5, and 1.9 knots respectively which are fairly decent times. A previous test I did with small 2-3.5 HP gas 4-stroke outboards on the same boat yielded an average max speed of 5 knots. Battery life can run from a little under one hour at WOT to 6 hours using the max range speed. The twist throttle smoothly regulates the thrust in both forward and reverse. What's really nice about this motor is that it's powerful...and quiet. And, considering that more and more lakes and waterways are going green, it's just the thing to meet the basic requirements being imposed by the locals.
