Slabquest, my Seasport weighed 6.400 lbs dry. With a load of gear, fuel and water it weighs over 10,000 lbs and that's usually what I'm packing when we go on our trips. I added a nozzle to the Yamaha (like you see on tug boats). It compresses the water as it's drawn through the propellor and provides even more thrust. Like you I have over a thousand hours on my Yami and it hasn't missed a beat.
