Author Topic:   Fuel Consumption Report on 8hp 2 stroke

I just got back from an 11 day fishing trip and thought I would post a fuel consumption report on my 8hp 2 stroke 1988 Evinrude .... I used the 8hp Evinrude 2 stroke kicker motor almost 100% of the time... I started the engine around 8 am and did not turn it off untill around 5 or 6 pm... I put on 80 to 90 hours on this engine during my trip...

I averaged about 2 to 2 1/2 gallons of fuel/oil per day as I was constantly trolling for Salmon... Even when a fish was hooked, and netted, the engine remained running.. The kicker motor ran excellent and there was virtually no smoke seen or smelled other then one time that I recall... I was very impressed about the lack of smoke...

On my Outrage 18, this kicker pushed the boat at a top speed of 5 to 6 mph with the main, 150hp engine, trimmed all the way down in the running position. The main engine being down does of course slow the top end speed down... The speed was measured on the paddle wheel of the fish finder..

I have owned an 8hp Evinrude 4 stroke before but never checked the fuel usage... If an 8hp 4 stroke were to burn 50% less fuel then my 8hp 2 stroke, it would only use 1 to 1 1/4 gallons of fuel in an 8 to 9 hour day.. I personally could not justify going out and buying another 4 stroke as it would only save me about $2 to $3 per day in fuel and the cost of the 4 stroke would take many years to pay for the 4 stroke from the savings in fuel... As said above, the 2 stroke hardly smoked at all and was also very quiet, less total weight then a 4 stroke, and a lot less moving parts then a 4 stroke...

I am still not sold on 4 strokes yet. I would also not want to troll all day long using my 150hp that burns a lot more fuel and smokes much more then my little 8hp...

I recently added a Dual Binnacle mount Engine Control on the console of the Outrage 18... What a pleasure to be able to control the kicker entirely from the Helm. The only time you need to touch the kicker is for pull starting the engine once in the morning and pushing the stop button once in the evening. Several other people on this forum have somewhat the same setup for their kicker. There are some photos of my installation here:
Note: some photos do not show the new dual binnacle installation but others do..
A friend of mine likes this setup so much that he just purchased a Dual Binnacle Control and is going to add it to his Montauk...

Fish report:
Fishing was great.... Large Salmon were running and we landed several 20 pounders and 25 pounders, two 27 pounders, a 30 pounder, and the best was a 35 pounder... We also saw several 40 pounders caught and 1 huge Salmon weighing in at 52.5 pounds.... These were all Chinook (King) Salmon... The Coho (Silvers) are getting ready to come in.... I will be heading back there in a couple of weeks to try my luck again.... The Outrage 18 is an awesome boat...

Anyone else have any other fuel consuption reports on small 2 stroke or 4 stroke kickers?

Nice photos!
What did the dual binnacle control set you back and where'd you get it? It looks great!

I purchased the Dual Binnacle Conrol on eBay for $25.00.....
Yes, $25.00......
These controls were in great condition except for the plastic cover which set me back $24.00 from the Bombardier dealer....
The Binnacle control even came with Four 18' control cables.... I used two of these control cables on the Outrage and they were the perfect length for the kicker motor..... I gave the other two cables to a friend of mine who is going to convert his Montauk to dual cables and control his kicker just like my setup... I don't know if the 18' cables will work on his Montauk but we are going to try them just the same....

Thanks and Regards,
Joe Kriz

Very nice setup. dual binnacle is the way to go.

I don't think you would want to go out and replace the 8hp 2s with a 4s. That would not make sense. Besides, looks like you have two really nice motors already.

For a new purchase though, I am not all convinced that with a current 4 stroke or DFI main engine, you would even need a kicker. They idle way down with no problem and they have much better fuel efficiency. My FICHT will push the boat along at <2kn happily, all day long.

But if you had to buy a new one today, you'd probably be better off for resale when the emissions standards kick in. Plus the operating cost is a benefit, it just won't pay for a new one anytime soon.

Too, we sportsmen should be conservators of the environment that we depend on. It is absolutely astounding how much water a single droplet of oil will cover.

Very nice setup,good pictures,and a good fishing trip report.
I have a 2003 9.9 hp 4 stroke merc for a trolling motor on my 25' revenge WT.It replaced a late 70's 25 hp 2 stroke merc. I don't have fuel consumption figures for the old motor because it ran off my main tank which is full of premix.I do know the new one uses about the same as you,
2-21/2 gallons per day,depending on wind conditions.
The remote controls for the kicker are the only way to go,I have electric start as well so all I have to do is raise and lower it into the water.
In a testimonial to standardization I removed a late 70's
2 stroke and put on a 2003 4 stroke and everything plugged right in. Wiring connector,shift and throttle cables, even the mounting bolts went through the same holes on the bracket.It simply fell onto the boat. The only modification needed was I had to reverse the action of the throttle cable, and it is simple to do at the console end. I could not believe it was going to be that easy.
Regards, Brian
