With a light to moderate load, you might want to power with a 90 hp engine.
It won't be working nearly as hard and you'll probably get better economy.
When you carry a full load, on the odd occasion, you'll have the power to get you where you want to go.
What is your intended use of the boat? An Angler, as you know, is ideally suited for fishing. If you are slow cruising, the 22 Cruiser is much preferred with a bigger dinette and nice sized galley.

Is the Yamaha a 2 stroke, a 4 stroke, carb. or EFI? This all makes a big difference on fuel economy. Try not to compare a boat to a land vehicle when it comes to MPG. This will not work for boats due to different factors with vessels and currents. Use Gallons per hour for a given RPM then figure your distance. This will accurately calculate your fuel consumption for a given RPM, load, vessel type, weather, and currents.

8 mpg on step at 20-30 mph would be amazing. I honestly think it's impossible. I get a lot of 3-5 mpg and I can't imagine doubling it. I do like the Yamaha 70 though, but I've heard it doesn't have the grunt of larger displacement 70 hp outboards - no idea if that is really true of not.
With 8 persons aboard, I feel that the 70 would be marginal. The 90 would get the same millage as the 70 at the same speed. But then 8 persons aboard would be crowded! I have always been glad I had a 90. Running heavy, at times it is marginal. The early (pre 1987 boats had the 70), but those were lighter engines, being 2 strokes. Thus a lighter and flat Bottom boat.
I was guessing that a 90 and a 70 at the same speed would have similar fuel economy, in which case I would likely go with the bigger engine. Anyway my goal is to maximize fuel efficiency for long distance travel. I want to cruise on a plane but DO NOT need a fast boat. If there’s one thing I learned on my 5k mile trip on the Isabel it’s that there are a lot of boaters out there that need to slow down!
In addition to wanting a light hull, I love to fish saltwater, and the Angler’s 6’ 4” aft cockpit is huge compared to the 4’ 6” on the Cruiser and bigger still than the 5’ 1” cockpit on the 23 Venture which is the other model I was looking at.

Yes your guess is correct.
I ran a search on a number of threads about what fuel usage has been reported. The most optimistic have been the ones from Boat Test. com and Honda. The Honda test used only a 50 hp, which is definitely an engine too small for the boat for conventional use. In talking to owners they cited 12 to 13 mph as top speeds with a light boat and ideal conditions. The Honda tests bear this out.

Probably the best MPG is in the 5.6 range at a plane in the 10 to 13 mph. But this is unrealistic for average boaters.
Figuring on 4 mpg, keeping the boat light, and good conditions would be reasonable if you want to be on a plane. In realistic conditions where you may be beating into head seas and heavy wind, then you have to revise your mileage, which wi be lower.
(I did misinterpret the 8--). It would be very unrealistic to consider 8 mpg, unless you are running in the 5 mph range. If you want to reliably get a range of 200 miles, then you probably would have to do some of this at displacement speed. This is consistent to what I have observed with the 22.
If the issue is fuel cost--the average boater spends more on dockage, upkeep and insurance than the fuel costs. On a boat doing the "great loop", then fuel costs becomes significant.
If you want reliable range over 200 miles, then take additional fuel.
We find that when long trips in the 22 or 25, we use a variety of speeds, but much of it is at displacement speeds, which is consistent with our past history of many thousands of miles in sailboats.
On my 22 cruiser I can sometimes get close to 5 mpg at cruising speed, but conditions have to be right. For planning purposes I use 3 mpg to figure ranges between stops. Since in my use, the boat usually cruises at around 3.5-3.7 mpg, this builds in a good cushion for contingencies. This gives a nominal range of 140 miles on standard fuel. Cruising speed in this case is ~20mph. BTW, once the CD is fully on plane, the mpg does not change much with speed.

Like you, I can get 5 MPG and plan on 3 MPG. When I get 5, it means the boat isn't full of cruising/fishing/shrimping/hunting crap and I keep it at 4500 rpms, which is around 17-18 mph on mostly flat water with little current. I actually get 4-5 or very close to it very consistently when I use it as a day boat for fishing over in Seward or Homer. Even at full throttle and 30 mph it still gets a bit over 3 MPG, so that's a good number to plan with. I can't imagine ever getting 8 MPG....I'd love to though because often I'm hauling around 30 gallons of gas on my little adventures into PWS and would never have to again. Fun things just burn the gas.....lots of gas....the more fun the more gas.....lol....
This is true of all of Florida, and at some places up the AICW in the SE, as well as all of the GCICW all of the way to Brownsville.
But if you are taking the boat to the Bahamas, it will be loaded with other gear, and probably
Either the Angler with any outboard, and the Cruiser with any outboard, will be "shallow water boats". For example any boat going in or out of my home bayou hill have to get over a shoal which can be as shallow as 12" at an extreme low water event. 18" is not unusual in the winter.
The Yamaha 70 is a souped up 1 liter displacement 50 hp block with the same block as the 50 hp, and will develop its max hp at the high end RPM range @ 253 # wt.
The 90 is 1.8 Liter block, which it shares with the 75 and 115 hp block. The weight is 353#, only 100 lbs more than the smaller 70. We are talking about on the Angler which may or may not weigh what the factory says. (Most of the Cruisers are considerably over the weight given by the factory by scale weight.)
Will the Angler sparsely equipped get better mileage than a Cruiser 22 with minimal equipment? I contend that you probably will not be able to notice a significant difference because of so many variables. I don't know if it is range, or cost that drives your quest for information about "mileage". In either case, there are multiple variables. No-one can accurately predict what you will get to more than 1 mile per gallon variance.
I believe that you. have a predominance of testimony by a number of very experienced boaters which would suggest that the 90 hp would be a better choice.

I ran a 70 hp Yamaha 4 cycle with carbs for 17 years, running mostly heavy with 2 people on board in saltwater in all kinds of conditions all throughout the Broughtons and mpg would always be around 2.5 to 3.5.
Traded the Yamaha in last spring for a 115 Suzuki after running it last summer it seems to be doing a bit better performance wise.

Thataway I’m pretty much a minimalist, and going from my 16’ open aluminum skiff to a 22’ Angler is a huge step up in terms of what I can carry, but by most people’s standards I plan on packing extremely light to gunkhole the Bahamas. After a 5,000 mile run non-stop run in a small skiff you get a pretty good idea of what you need (really need) and what you don’t need. I started the voyage with too much stuff and stuff for two people since my son was with me from Marco Island to Savanna GA, and I was constantly mailing home boxes of stuff to lighten the boat. It’s always a trade off between your stuff and the weight of fuel, but for me it’s all about performance and efficiency, not cost. My longest single day ocean run was over 180 miles and I had many days where I ran well over 100, with some long grinding days riding big New England swells, and the performance of the boat in conditions like that always noticeably improved as the day wore on and I burned fuel and lost weight. Weight wise it was like going from two passengers to solo.

All things being equal with 2 boats, sea states, and speed, the only differences between a properly running and propped 70, 90, or 115 modern 4 stroke outboard on the back of any CD 22 is going to be the size of the lower unit, and the swept area of the internals of the engine. And the difference there will be statistically insignificant over the course of boat ownership because none of those things are going to be THAT much different in a given engine class. Now if that 70 hp Yamaha was a 3 cylinder, which it is not, there would less swept area giving it a slight advantage. Would it be enough to produce 10 mpg? No, but you might get a bit better economy than any other 70 hp out there because of it. I believe you would have hard time measuring the difference. As Bob said, these things are complex with lots of variables. And I'm with lots of other folks, these boats really shine with at least 90 hp hanging off the back. But, if you want to rig a boat with a 70 hp, it is your dime and has been proven to be enough motor to move the boat. However, don't fool yourself into thinking your going to get double the MPGs a 90 gets because you went with the 70. To put things into perspective, my small and extremely light, 16 foot flat bottom skiff does get 10 mpg with a 40 hp modern yamaha hanging off the back @ 20 mph and 4k RPM. If you really want 10 mpg, that is the type of boat you should be looking for. I'm sure the little 16 foot cruiser will provide that kind of efficiency as well.
The Isabel was a 16’ with a new 40 Yamaha and I got 10 mpg with a 3 blade prop. Tested a 4 blade and it went down slightly and top speed was also diminished. But anyway, I want a bigger more comfortable boat and the 22’ Angler is a nice size and I like the fact that it’s light(er) and can be rigged light. I’m touring the factory in February and I’ll have plenty of questions.

I made my voyage in a 16 foot center console Duroboat “tinny” with a 40 Yamaha on the back and a 2.5 Suzuki kicker. Isabel carried a max 34 gallons of gas and cruised at a max 10mpg depending on her load.
I started on the Mississippi in St Louis on May 1st of this year, and entered the Gulf in Mobile, ran west to Apalachacola where I made an open water jump to Steinhatchee, then north to Marco Island where I picked up my youngest son who had just graduated high school. Together we lived in the Everglades on chickees for a week then headed south to Key West and then on to the Dry Tortugas which was my first planned turnaround. From there we cruised north to Boca Chita where we crossed the Gulf Stream to Bimini For a long Father’s Day weekend, then returned coming in to Palm Beach Inlet, and then on to Savanah where my son flew home and I picked up my GF who joined me as far as Charleston. Then I ran up the east coast solo, spent a week in Nantucket, and then north as far as the Bay of Fundy. That’s where I had to call it quits for safety reasons due to a 30” hull crack that was letting so much water in I could hear the spray hitting the floorboards. I had run from Winter Harbor out past Machias Light/island in 6-8’ long period swells, and cruised into fog as I passed the light with another 10 miles to get to Grand Manan. I basically came into Seal Cove Harbor in a sinking boat, and even though I was able to haul her out and get the big crack welded, there were smaller latent cracks and I essentially condemned the boat. It was close but thankfully I never had to don my drysuit or activate my PLB.
I saw many amazing things on the trip, a HUGE gar on the TenTom, alligators, crocs and manatees, a free jumping marlin in the Gulf, a loafing swordfish in the Gulf Stream, whales bubble feeding on Stelwagen Bank, and finished the trip in the company of puffins in the Bay of Fundy. While at the dry Tortugas I got out of my tent at 2AM and greeted 19 Cubans on a boat/raft coming ashore, which was both an unforgettable and heartbreaking experience. I’m a fisherman, and along the way caught triple tail, sail cats, little tunny, mangrove snappers, amberjacks, and stripers (if I ever do this again I’m going to run slower and fish more!)
Altogether it was an amazing trip, lots of hardship living on a tiny boat with only cot-tents for shelter from the insects and elements, and at age 62 it was very hard physically, but It was a bucket trip list that I’d planned for nearly 10 years, and it was AWESOME!
