Heater Fan can I increase flow speed

[wayne99]

Just wondering if there are after market heater blower fans that I can purchase? My heat is decent but the fan speed is poor. Thanks

Do you have all three speeds? Is the duct work intact with no kinks or leaks? I just reinstalled a new heater in mine over a leaking core issue. It isn't a hurricane on high but I can feel the passenger seat vent sitting in the drivers seat with the boat no moving. Hard to describe how hard a fan blows.

Both of you purchase the same toy pinwheel and see how fast they blow. This would represent a poor man's anemometer.:D
