What do you think the range is on 2100 DVCC w/175 SWS Yamaha

Just like the title says...

What do you think the range is on 2100 DVCC w/175 SWS Yamaha?

factors:
- No bottom paint
- 97 carbed 175 sws yamaha
- I think the fuel tank is ~100 gal


I'd like to make a weekend run to Ft Jefferson (Dry Tortugas) and its about 70 miles each way. I'm thinking I might be too close to the margin for comfort.

What do ya think?

I would guess the fuel tank is the same as my 21SE. 95 gal, I am running a 200 Evinrude. If memory serves me, I have around 300 miles on a full tank. I think you should be OK. If you have a gps you could make some shorter trial runs to check your fuel consumption.

If you were to install a fuel computer, you'd know for sure what your range is because the unit would compute your fuel burn. :wink:

Also... if you pop the deck hatch to the rear of your fuel tank, it will have a tag on it (the tank) telling you what the capacity is.
No guessing that way.

yup.. while the flo scans are the best and the most accurate, I think the best deal is on the lowrance unit. I have the northstar unit, it is cheap and functional but for a couple of dollars more, I think the lowrance is nicer.

Keep in mind you cannot run the tank dry. The pick up does not go completely to the bottom of the tank and depending on pick up location and tank angle there may be as much as 10% of unusable fuel.

My rule of thumb is I never travel more than 30% in one direction and leaves me 60% for return trip. This gives me latitude for changing conditions and other variables.

Very true. The tag on my tank says 127 gallons, so I set my fuel computer to 120 at full.
I also set a low fuel alarm to go off at the 20 gallon mark.

My fuel burn at cruise is 12 to 14 gph, so that alarm gives me about a 90 minute run time at cruise speed. Plenty of time for me to get to one of my local docks for a fill-up.

Fuel computers are worth every penny. :wink:

he Megebyte, on that flo scan, to install, do all
you need to do is install that thingy on the two fuel lines and calibrate and you are good to go, or is there way more to it, I got one for my old boat from Jim, and the install was easy, those look cool !

I love the one built in the Yammy gauges.. Very accurate and a must have for anyone who travels allot. Like a cell phone don't know how I lived without one :lol:

When I installed my Navman 2100, the transducer was installed in the fuel line, the gage installed in the helm, and the power line connected.
It was that simple.
