  • Very loud and slow
Model: 4hp 4 Stroke Jet Pump Boat Engine
This thing came with oil leaked all over it. It was a mess. Wiped it down. Put it on a small 12ft kayak and it barely moved the 50lbs kayak plus me (140lbs) sitting in it. It is VERY LOUD for a 4-stroke engine. I wasn't expecting it to be fast but it was moving around 2.5mph to 3mph. I can kayak faster than this motor! Will try it again soon but the propeller jet stream system may not be a good design. ... show more
