Need some info on my newly purhased 1984 Outrage 18. Where does the water that collects under the gas tank ccess plates go?
In the drain area at the stern?
Or des it stay in the tank compartment.
Also what color would my deck be? Desert Tan?
Would like to re chaulk the deck tank cover as you people talked earlier.
I have a 78 13' but this is my first "real" whaler, any help would be great. Terrific website!

I have been working on a 20' Outrage and have discovered that water thru the ports above the fuel tank drains into the rear well. I left the ports open for a week with a fan moving air around and as soon as I closed the ports moisture appeared in the clear cover behind the console. The foam aound the top of the tank still seems moist. I may have to move to Arizona or near the Arctic circle. I don't think its a problem, just a "nature of the beast." Scott

Here's some information of general interest to owners of Outrage/Revenge hulls, all having built-in gas tanks. This is from the Owners Manual that came with my 18 Outrage, titled "Owners Manual for 18-25' Outrages".
Fuel Tank Installation.
"An aluminium fuel tank is permanently installed under the cockpit floor. A large floor cover fastened with screws outlines the tank configuration. The tank is set into a molded fiberglass cavity which is part of the fiberglass interior skin of the hull. Fuel leakage, if it should ever occur, will be contained in the fiberglass hull cavity."(a picture shows the bare hull cavity, veed in shape, into which the tank goes. The bottom of the tank is also veed to fit - note by LHG)
"In addition, under the center floor cover are molded-in tunnels. They provide the channel for steering, control, electric and accessory wiring cables from the battery and engine to the control console. These channels are separated form the fuel tank. It is normal for some water to accumulate in the tunnel and fuel tank area.
"Water in these areas will drain to the aft sump and out via the manually opened drain when the boat is underway, or by bilge pump.
Your boat should be stored with the bow slightly elevated and all drains open.
"All fuel tanks are pressure tested for leakage prior to installation. Tanks are set on cushioned straps to support the tank and prevent abrasions. Space between the tank and the fiberglass cavity is filled with a gasoline impervious foam. Large aluminium bars and flexible foam pads are placed on top of the tank to prevent any vertical movement.
After the tank is installed and all fittings secured, it is again pressure tested to ensure the entire system is fuel tight"
For any boat built before 1988, you should check the fuel lines alcohol damage. They were not installed of alcohol resistant material and may need to be replaced. A new Federal fuel line standard mandated new type of fuel lines in 1988, because of the ethanol being added to gas. Today, I have found it impossible to buy any gasoline without 10% ethanol content. This stuff can dissolve the pre-1988 fuel lines used in boats.
