I'm kicking around the idea of moving up from my current 232 with f150s to a 282 with f225s but I'm a bit concerned about how much more fuel I may burn. I've compared the performance specs on the Grady site and it seems to be about a 10%-15% difference. When we spend the day trolling the inshore area, about 40 miles out and trolling for 8 or so hours I usually burn about 70 gallons where as a canyon trip runs about 90 gallons. The Yamaha performance bulletin says the 282 with f225s cruises at 4000rpm 32.7mph and averages 2.06gph. All theses performance bulletins always seem somewhat optimistic so I'm hoping some 282 owners can help me out. Thanks.

I believe the performance bulletin has the motors propped with 19" pitch which are too much for this setup. I have basically the same setup running a 17 pitch 3 blade yammie prop which i had a prop shop add some cup. My true numbers are as follows cruise 3700 running 24mph getting about 1.5 to 1.6 statute mpg. At 4000 roughly 28mph at 1.5 mpgs. My sweet cruising rpms are from 3600 to 3800rpms which net me 1.5 to 1.7 statute mpgs. running 4 grand and higher drops mpgs to the 1.4 to 1.5 range. I had 19p props on the setup but couldnt get above 5400 rpms wot. Not good for the motors. The setup i have now gets me a wot of 5800-5900 at 43 mph.

Thanks for the replies. The test data I have from Grady was dated 5/4/01 and they were running 15 1/4" x 19 props. The results were as follows:
RPM MPH GPH MPG
1000 5.6 2.5 2.24
2000 9.0 5.7 1.58
3000 19.4 9.6 2.02
4000 32.7 15.9 2.06
5000 41.8 27.1 1.54
6000 48.8 38.2 1.28
Does this seem somewhat accurate? If so, I'd be pretty happy with those numbers at cruise. Any more feedback would be greatly appreciated.

Over 2 MPG at cruise seems high. This thread discusses the 282 and has a link to performance specs for F250s which claims 1.86 at cruise.

2002 282 with F225's yami 15x19's
usually run the boat heavy: full fuel, 4 guys, gear, etc.
nicer normal conditions cruise at 3900 rpm 26-26.5 knots burning 15-15.5 gph
4000 rpm sees 27-27.5 knots burning 16-17 gph
choppy conditions where i have to throttle back to 35-3600 rpm sees 22-24 knots burning 13.5-14 gph
if you run light, you'll see a knot or so better speed for same rpm and fuel burn.
overall, pretty happy with the ride and economy of boat and set up. the 282 hull rides very neutral with little ot no trim tab input required. she's significantly heavier and longer than a 23' boat and thus rides much better in heavier seas than a 23' boat. went from a 22' WA to the 282 and the ride was night and day. my body and my dad who is not getting any younger appreciate the better ride especially offshore.
i also bought a couple marine bean bag chairs for the boat and coupled with the bigger boat, my dad really relaxes and enjoys the ride--if i wasnt driving the boat, i'd opt to sit in a bean chair in the cockpit myself underway!

Those numbers seem really good. What is your WOT RPM and speed with the 19" props?
not often open her up to WOT as the sight of 30+ gph on the gauge is :jaw
but, i sometimes to "exercise" the motors and kicks :dance i let her open up for a minute.
max rpm a little low at 5300 or so if i remember correctly. could be 5400 but not over 5600.
loaded she tops out at 34-36 knots, light i've seen 37+.
not sure if max rpm is that important for 4s motors compared to a 2 stoker.
almost 800 hours on motors so far, most 282's with F225 came equipped with the 19 pitch props.
have a new set of Merc SS props in same size and pitch, may try those out next season.

The 19" pitch props are too much. The 4S yammies need to turn toward the upper end of the rpm range 5700 to 6000. I agree that rarely we rum em wide open but the extra load turning the 19" props will shorten the life of the motor-yes you will see better mpgs but is it worth it? I would call yamaha to verify. . I can tell you from my setup 1.5 to 1.7 statute mpgs is what i get. My motors have 850 hours on them.
BC282,
Thanks for the reply. Those #s seem very impressive, in fact there are very close to what I see with my 232 Gulfstream. Just need to decide whether or not I want to sell a great boat. :lol:

My 27 Islander powered with F150s does ~14 GPH @ Cruise 4500 RPM ~28-30 MPH. We were 40 miles offshore last weekend in rough seas grouper fishing and I burned 71 Gallons--left the dock 0630 and made it back at 2130 loaded with 250 lbs of grouper. We were full of fuel (200 gallons) and water tank full with 4 souls on board. Motors never shut off all day. We dodged water spouts and rain all day. I ran directly into seas on way to the hill 39 miles. I have been to the FL Middle grounds overnight which is a 96 miles run each way. I burned 147 gallons on that trip. Switched to the aux tank (50 gal) when I was coming into the inlet.
My rig has plenty of power as I don't see you running much faster on a 282 than a 23 offshore especially in the Atlantic. I would imagine the 282 would burn qute a bit more than your 232. If you are looking for more room, take a look at an Islander....it looks like it burns the same as your 232. Not much diff in the 282 vs 270 besides an aft bed and you can legally trailer the 270 if you have the rig to pull it.

My 2006 282 with F225s gets me about 28mph at 4000 rpm and 1.4mpg. Occasionally i can get it to 1.5mpg. These are off the yamaha gauges. Top end is about 42mph and 5800-5900 rpm and I don't look at the MPG!!
I usually have freshwater in the tank and at least half a tank of fuel. I can't imagine 2MPG!

2005 282 with F225's.
Just over 1200 hours in the Pacific NW over last 5 summers. Most trips are with 5 people, average of 350 lbs ice, running into a 3-4 foot swell, and 5-10 knots of wind.
Fuel burn is 1.22 nmpg based on all condition average. Flat and glassy could be 1.4nm or slightly more, and rough and snotty can be down to 1 nmpg.
This is with Saltwater Series II 17" wheels, bottom painted. Loaded with a lot of gear, raft, outriggers, etc.

In reviewing the numbers in this post, it appears that the boats with 19" props get great gas mileage of about 2 MPG, but are at the low end of the optimal WOT RPM (~5400). On the other hand, those with 17" props get closer to 1.5 MPG at cruise and buzz closer to 5900 WOT which is the high end of optimal range. Thus is may be that the 19" is slightly overproped while the 17" is slightly underproped.
Does anybody have an 18" prop on their Sailfish?

19 is definitely over pitched with 225's and 17 is over pitched running 200's. 225's should run 17's and 200's should run 15/16's.
The misleading fuel numbers make it very tempting to run higher pitch but over propping is killing the motor.
Need to be able to get in that proper upper rpm range that the motors are rated for.
The sailfish also is no comparison to an islander. Very narrow beam on the islander, less fuel capacity/weight, etc., etc.
An islander will fit inside a sailfish, as a sailfish will fit inside a marlin. All different animals.
