just bought a 2002 22' CRUISER w a 100 HP Yamaha and a 9.9 kicker, wondering what kind of range I can get w 46 gallons of fuel. I was told there was a chart here or on the c-dory site but I can;t find anything. any ideas on how I can ball park economy?

I have a 22 Cruiser with the Mercury 115 HP 4 stroke EFI. On Plane, I get about 2.9mpg-3.1mpg. At hull speed (5 mph), about 6mpg. Colby

A lot depends on how you run the boat, and load you have. Colby's numbers seem a little low, on mpg. There have been several performance reviews such as Boat Test.com. These have also been used for the factory brochures and web sites in the past. However these are optimistic, since it usually a new boat, no bottom paint, no water, two persons aboard, and only partial fuel load. Also most of the fuel flow studies are with 2 stroke 70 or 4 stroke 90 hp.

The current brochure gives up to 250 mile range. That would have to be a light boat, and some displacement speed. Figure that you only probably have 22 to 24 gallons usable in each tank. Then add in a 10% factor for "safety". Assume 4 miles per gallon (may be closer to 3.5?)..Lets say a respectable 4 miles per gallon, and 44 gallons usable. That would give 176 mile range less 10%, or about 160 miles. There have been times on long trips, where I have dropped down to displacement speed where you can get over 5 miles per gallon. That would give you about 200 mile range.

This is why I have had fuel flow meters on my C Dorys. Most will give MPG and amount used. They can be quite accurate when calibrated.

You should average about 3.5 - 4 mpg depending on weight in boat, speed, prop pitch, hydrofoil and/or trim tabs.

Here's a chart from a similar thread:

With my Honda BF90D I plan on 3 smpg at cruising speed. The actual mileage is a bit more than that, but by planning for 3 mpg, a reserve gets built in.

Boat loading makes a difference. This is not just weight, but distribution. Having a lot of tab out to get the ride right will cut the mileage (and top speed) a noticeable amount.

The Boat Test numbers posted are for a minimally loaded boat and are optimistic compared to my boat.

This does not help you very much but up here in Canada mine works out to 1 1 litre per 1 nautical mile

Very easy for my brain to calculate - 20 nm to gulf islands = 20 litre jug!

So:

How would 1 liter per nautical mile compare with 1 statue mile per quart?

Simplification: 1 liter per nautical mile equals (~) 1 gallon per 4 statue miles, or

= 3.5 nautical miles per gallon. (Full Circle)

As usual, your mileage may vary! Laughing

We have the cc-23 venture with a 115 ct Mercury At cruise 3500 rpm (16mph)we get over 4mpg at 4000 rpm (20mph) about 3.8 or so and the best is at 1500rpm (6mph)and 6mpg In 3 years of running we average out to 3gallons per 1 hour of engine use The venture is about 800lb more then the cd 22.

BTW we had aCD22 with a 90 Hp Suzuki and we would get similar return

Just remember, there are only places to get fuel in Isle Royale. I've been up there the last two years with a small group of C-Brats, and if I leave Grand Portage full, I can get around the island to Rock Harbor and top off, then make it back. (Wendigo Ranger Station is the only other place to get fuel on the Island.) Colby

John, if you are around there in July, I believe Tom on C-Otter and some others will be up there soon after the 4th. He loves to fish, and is also a scuba diver. I'll miss out this year, but hope to be back the following year. Colby

That is exactly how I calculate it and my tanks hold 85 litres each. I'm not sure how much is usable.

I have a new 115 Yamaha on my 22 Cruiser but don't have the fuel flow meter. expecting much better fuel performance than my honda 75. Both are the same weight and can run same speeds at lower RPM with max speed of much higher if I want it.
