Heater - 2 or 4 Outlets?

[cab13367]

Thanks guys. I think you've convinced me to get 4 vs 2. I am thinking that I would install vents 3&4 right next to each other under the driver's seat (where there is one installed in the pic). That would minimize the amt of storage space lost as well as the length of the hose from the heater unit.

Placing them under the driver's seat should allow it reach behind the driver's seat and directly across the boat. It would even reach to the rear bench seat but if you're cold, you wouldn't be sitting all the way in the back when the boat is moving anyway.
