We have 1980 42 convertible with a 30 gallon waste tank. The sensor manufactured by JENSF is showing full even when tank is empty. Any one had problems with those and where can I get a replacement or is something I need to remove and clean as it is some swort of float. thanks ron 206-546-5722 Edmonds Wa.

"Thanks to Waggoners (a good Northwest boating journal) you know the weight of one gal of water is 6.2lbs and diesel is 6.7 lbs. Doing the math my fuel weight can be as much as 3,350 lbs and water 1,085 lbs. That's a lot to haul around. water is heavier than diesel, ( diesel floats on water ) so it would seem " the waggoners " is not a good boating journal...! eric ----- Original Message ----- From: [email protected] To: [email protected] Sent: Friday, September 03, 2010 3:42 PM Subject: Re: [UnifliteWorld] Re: cruising rpm? Imperical is not Celsius, liters, or kilos. It is gallons, pounds, and fahrenheit Canada would be kilos per liter. The point about specific gravity and temperature as it relates to fuel weight on board is moot. Apart from knowing the approximate volume of a full fuel tank, we have no idea the volume after we have run for an hour or so. Unless you have fuel gauges that show you how many gallons you have on board you can't produce more accurate calculations than you have instruments to measure. Besides, we are not making a trip to the moon, these are cruising boats.

Therefore, an Imperial gallon is bigger than a gallon in the US (or is the Imperial gallon weighted at 1 degree C). Does Canada sell fuel in Imperial gallons? --- On Fri, 9/3/10, Monty Montaine <[email protected]> wrote: From: Monty Montaine <[email protected]> Subject: RE: [UnifliteWorld] Re: cruising rpm?

Same on my boat which is a 42' with twin diesel. As best as I can calculate the miles/gal is about the same between 11-16knots. Below is better, above is worse. The only real difference in that range seems to be overall weight which is in large part a function of fuel and water load. I have 4 fuel tanks (fwd-50gal, aft 50gal, and saddle tanks at 150gal ea.) and 175 gal of water under the aft cabin bunk. The farther forward the weight the better so I manage the aft water load, keep the aft fuel tank empty and use the forward fuel tank as the emergency reserve should I screw up on the saddle tank load. Thanks to Waggoners (a good Northwest boating journal) you know the weight of one gal of water is 6.2lbs and diesel is 6.7 lbs. Doing the math my fuel weight can be as much as 3,350 lbs and water 1,085 lbs. That's a lot to haul around. There is some good news. The extra weight seems to effect the mileage more the faster you go, so - I run fast and empty as possible to get to the islands then fill up and cruise slowly around. It works perfectly for the northwest where there are lots of choices once you reach your destination area. The big negative is fuel price differences. This summer, fuel in Seattle was $2.75 as I left. The farthest point north I traveled in Canada it was $4.40/gal (all adjustments to US $ made). Kinda suggests you stay close to home. Any other fuel saving suggestions? Drift with the current? Anything but buy a sailboat - please. -- You received this message because you are subscribed to the Google Groups "UnifliteWorld" group.
