You are correct. Corrugated bilge pump hoses, with their ridged internal structure, restrict flow and are not the best choice for runs of over 2 feet. For greater efficiency, it is recommended to use smooth-bore bilge pump hoses, which offer up to 30% greater efficiency than corrugated hoses. However, if the discharge port is less than 2 feet from the bilge pump, the difference in water flow rate (GPH) between the two hoses is less than 5%. Therefore, using a short corrugated hose for a bilge pump on small plastic boats, Jon boats, portable boats, and inflatable boats will not have any trouble moving the water out of the boat. Considering that smooth-bore hoses are 3 to 4 times the price of corrugated hoses, it would be a good choice to use a short-corrugated hose for a small boat. Thanks for watching my video. Norman
Todd, The pump in the video uses a water sensor level. When the water level reaches 2" it will auto-turn on. I use 12AWG wire. Thanks for watching my video Norman
You can choose a 600 GPM or 800 GPM Shoreline Automatic Bilge Pump. I use the 800 GPM model. Click the link to review the information or to purchase: amzn.to/3KfX53R Thanks for watching my video Norman
Perfect thank you
You're welcome! Thanks for watching my video!

corrugated discharge lines are the worst for bilge pumps as they impede flow and reduce the effectiveness of the pump.

This pump has a water sensor vs float? And did you use number 10 or 12 AWG?
