Great Upgrade!

Previous water pump was allowing a lot of coolant to dump during warmer conditions. This water pump is so efficient that I haven’t seen a drop hit the ground in any condition so far! Keeps the bike cooler and holds on to coolant a lot better than OEM. Also, looks awesome! Definitely a good upgrade for anyone looking to improve their cooling system and or hot climate riders.

Worth it for either two or four strokes.

I install Boyesen Supercooler water pumps and impeller on my motorcycles so I don't have to worry about overheating.

Great product and easy to install

I bought the the supercooler to help my bike run cooler. It was easy to install and adds a factory bike look to the bike. I also added engine ice to lower the temps by 10-20 degrees.

A: That is a good question. I have always used the Boyesen cover with the Boyesen pump impeller because it's a kit and they were probably designed to work more efficiently together.
