You were informed correctly. Grady doesn't use fiberglass tanks.

I found myself with water in my tanks that got there when whoever was attempting to syphon gas this past winter (unsuccessfully) left the filler caps off when their deed was done. I noticed the situation but only after significant rain had fallen. The boat yard swore to me that they checked the bottoms of both tanks in my 1997 Voyager 248 and found no water. When my main tank got down to about 1/8 full I switched to the Aux. It took about 5 minutes for both Yamaha 150 (2 stroke) engines to sputter and stop. We were able to get them  going again by draining the water separators. We repeated this process three times before all trace of water was gone. The moral is: Those water seaparators are effective!

I have an 83 gulfstream and it has aluminum tank. Infact I just had to replace it because it pitted through.

I had it made through http://www.custommarinefueltanks.com/ It is the only tank in that model It was a 65 gallon tank. They upgraded it to about 70 gallons and I still had room to spare.

In retrospect I wish I had gone larger with that tank and anyway I can alwayse fit another tank where the inboard motor was.

NP, I wish I had a bigger boat :)  but the bigger the boat the more gas you burn right?LOL. 

I'm still hoping they come out with a diesle out-board.

[QUOTE=ewkearns]I remember diesel outboards from 40 years ago. Problem was that they didn't have a lot of power and they weighed about a million pounds. I think Yanmar is still making one.

I've got two 140hp Suzuki 4-strokes on my Grady and have been very happy with their thriftiness, though I think I gave up some speed from the 150hp Yamahas. Oh well, boating where I do, there aren't many days that WOT is an option.... unless you want your kidneys in your hip pocket!

I would hope with today's high tech alloy's and composites an economic weight and price diesel could be produced in an outboard. Maybe I'm dreaming.  I know what you mean about being able to travel WOT. Don't get to do that much but I can cruise comfortable at 27 mph at 4000 rpms.
