I recently bought my 2009 230 select used. From the specs I found online I thought it had a 50 gal fuel tank. I've only had it on the water 3 times and each time I ran about 14 to 15 gallons through it each time and the fuel gauge indicated that I had used over 1/4 tank to near 1/2 tank of gas. I downloaded the owners manual from Sea Ray and found conflicting information published there. In the spec table it shows 50 gallons (45 usable) but in the paragraph about the fuel system in mentions a 40 gallon tank. I hate to run it out of gas to find out which is correct.
