The new power cat has a 38 gal fiberglass holding tank and no level gauge. Access to the tank sides is limited, reaching through a 6" port in the adjacent flotation tank.

US Marine makes an ultrasonic gauge that mounts thru a 1" hole in the top of the tank, available at Defender for $150. Anyone have any experience with this model, or any advice about other models?

We have used the tank monitors that tape to the outside of fiberglass
tanks on two trawlers over almost 20 years and find them easy to use,
accurate, and reliable. They used to be manufactured by Snake River, but
now are manufactured by SCAD Technologies:

Available from Defender:

They're easy to install on the exterior of any type of non-metal tank
using their tape kit; they also make a sending unit which utilizes a
tube through the top of a metal tank.

I have had the same one for 5 years. For the most part it seems accurate.

Right after emptying the holding tank it jumps up to full. Not sure what's going on in there but after an hour or so it goes back to normal.

The gauge increments are kind of broad, with only a few markings.

I have it in a 100 gallon, stainless steel waste tank, mounted thru a 8", pvc access port.

Mark,

I've been using the Hart Systems Tank Tenders for about the last 30
years. I have the five tank version set up to read port & stbd. fuel,
fresh and drinking water tanks, and the holding tank. The system works
with 1/8" dip tubes that enter the top of the tank using a supplied
penetration fitting that requires only a 10-32 screw hole in the top of
the tank. I put the hole in the the top of a plug or ell fitting so I
wouldn't have to drill into the tank. It connects with 1/8" nylon
tubing that routes as easily as a wire of that size.

The accuracy, once empirically calibrated, is very good. I can
typically judge how much fuel I'll take to within one or two gallons out
of 300, likely the accuracy of the dispensing meter.

I did have a problem with the holding tank dip tube clogging even though
I ordered the unit with a "purging valve" that allows higher pressure to
be applied to the dip tube to blow it clear. I eventually resolved that
issue by fashioning a conversion to a 1/4" plastic dip tube on the
holding tank.

No connection to Hart Systems, I just like the product.

Just had an unusual experience. We are sitting here in our slip at Pikes Bay
Marina, near Bayfield, WI, nearing sun down and a bad looking Customs and
Border Protection boat comes in, prowling around. That is unusual in that we
are about 150 miles from the Canadian border. This boat had four 300 HP
outboard engines hung off its transom. Interesting.
