Just checking on possible excess fuel consumption for a 1996 150 Yamaha 2 stroke with carbs. My motor is using about 40 liters of fuel every hour. I typically run it at about 3800 RPM whieh equates to about 28 mph. I love the motor because it is basically bomb proof but I am wondering if it is burning too much fuel. Comments?

Sure seems like a lot, thats almost 10 gallons an hour..
2 strokes are thirsty though.
Has it been tuned up lately, plugs etc ?

Look up yamaha USA outboard website,hit performance bulletins, fuel consumption rates are posted.8.8 gallons an hour sounds about rite and not much worse than a 4 stroke 150.US gallons are slightly smaller than our gallons.

Pump your primer bulb to see if it gets hard. If it doesnt, it may mean fuel is bypassing a needle valve or possibly a fuel pump diaphragm.

I think you sound pretty darn close to what the thing should burn. When troubleshooting fuel economy on a few boats in the past, I found the best results were from propping the motor on the light side, allowing it to hit near max revs with a moderate load.
Island Fish Lifter's idea would be a simple one to check.

Had a 135 yamaha 2 stroke carbed on a 17 Double Eagle, about 7 gallons an hour at 3/4 throttle sorry can't remember the rpm. Around 30 miles an hour.
If I didn't want to wait around and pinned it she burned waaaay more, as Roy said the amount of weight made a BIG diffrence.

LOL Trust me Jimbob is doing just fine the gas he is burning is looking for halibut holes and running around looking. As you know an older 2 stroke like his loves to eat gas at idle as it just pours it in!!!!!!
He needs to learn to sit and stay and make it pay,and not move 3 or 4 times in a day halibut fishing.
We have a new nick name for him and his fishing partner but I wont put it on here but his handle is the "MUPPETS" and it goes for the both of them.LOL
The 2 of them are great guys his partner ive know for almost all my life that why I introduced them to Jim. Ol Bill has been in the fishing industry for a very long time and most of you have some of his manufactured gear on your boats today, he is like a 2nd father to me and treats me like his son.
The 2 of them will figure it out as my buddy and I say all the time to them both.
"we dont know nothing were just dumb kids"
</u>LOL LOL
Good luck "MUPPETS"

Statler & Waldorf
Don't worry Roy, Statler and Waldorf (Jimbob and Bill) a.k.a. the Muppets now have a new theory to improve gas mileage on my boat. It's a simple theory really.... We are going to turn off the key for a minimum of 4 hours every time we go halibut fishing! Should work fine. Thanks to everyone who provided their thoughts on fuel ocnsumption. I will let you know how my new theory works. Keep your eyes peeled for a 19 foot Glasply that is anchored on the halibut grounds. Wave as you go by. Hopefully we won't be moving and saving fuel lin the process!!!
I am pleased to report that fuel consumption has vastly improved recently on my Glasply as a result of anchoring in one spot rather than chasing around to several spots during the course of the day. What a novel concept!!! Statler and Waldorf even managed to land a 38 pounder the other day in the process. The Muppets rule!!
