Determining the exact size of your fuel tank on the 2004 Crest Caribbean tritoon without access to an information plate or accurate measurements can be challenging.
you can try a few different approaches to get a better estimate:
Owner's Manual or Documentation: Check the owner's manual or any documentation that came with your tritoon. It might contain information about the specifications of the fuel tank, including its capacity.
Contact the Manufacturer: Reach out to Crest Pontoon Boats (the manufacturer of your tritoon) or their customer service for assistance. They might be able to provide you with the specifications or help you identify the fuel tank size.
Boat Forums and Online Communities: Visit boating forums and online communities dedicated to Crest Pontoon Boats or boating in general. Other owners of the same model might have encountered a similar question and could share their experiences and knowledge.
Professional Inspection: Consider having a marine mechanic or boat technician take a look at your tritoon. They might have experience with this model and can provide a more accurate estimate of the fuel tank size based on their expertise.
Physical Measurements: While you mentioned that accessing the fuel tank and making measurements is challenging due to its location, you could explore options for safely and accurately measuring the dimensions. This could involve removing panels or parts temporarily to gain access.
Estimate Using Fuel Consumption: If you have used the tritoon and know its average fuel consumption rate, you can estimate the tank size based on the range you've experienced. Keep in mind that this is a rough estimate and may not be as accurate as other methods.
