OUTRAGE 22: Converting to 122 gallon Fuel Capacity
OUTRAGE 22: Converting to 122 gallon Fuel Capacity
Q1: can an OUTRAGE 22 be converted to 122-gallon fuel capacity from the standard 77-gallon capacity without much trouble?
Re: OUTRAGE 22: Converting to 122 gallon Fuel Capacity
I don't think this modification can be accomplished while meeting your criterion of "without much trouble."
The larger fuel tank option eliminated the aft cockpit live well. To accomplish this now would required a new fuel tank, cutting out a portion of the hull liner, and creating a new deck cover plate. That certainly is not in the category of "without much trouble."
If there was an absolute need for greater fuel capacity, installation of a second semi-permanent fuel tank on deck would be much simpler.
ASIDE: What motivates this change? Modern outboard engines consume fuel at a rate of about half compared to the outboard engines used when the OUTRAGE 22 was initially designed. As a result, the fuel endurance of the 77-gallon tank is effectively double what it was back in the 1980's. With a modern engine a cruising fuel economy of 3-MPG is possible, so 70-gallons consumption, leaving 7-gallons in reserve, means a range of over 200-miles. For a 22-foot boat at 25-MPH, that is eight hours of running.

I agree with jimh's comments on the reduced fuel consumption of a four-stroke-power-cycle outboard engines.
I still may want to add fuel capacity for weekend trips Catalina Island or for long albacore fishing trip.
I think a small [on deck fuel] tank in the aft [fish] well wil [add sufficient fuel capacity].

If you feel that you need that much fuel I'm sure it can be done.
The bulkhead between the fuel tank cavity and the rear fish box will have to be cut out. The cut out area will need reinforcement with fiberglass.
Figures 1, 2, and 3 shown my 1980 Revenge 22 without the foam around the tank being replaced. Your hull liner should be the same as the Revenge 22. A 122-gallon fuel tank will be extremely heavy when full so I believe you will want to reinstall the foam around a 122-gallon new tank for added strength.
