3 hp outboard--how far

4057 Views 31 Replies 14 Participants Last post by  IStream
So I have owned many outboards but never a 3 hp and usually over at least a 20hp with a separate tank. Can anybody give me a rough ball park figure on how far a Yamaha 3hp outboard can go on a tank of gas? I ask for the slip I reserved for my boat has a canal about a mile and a half to go down to get to sailable waters. I will of course carry an extra 2-3 gallons on board but still curious.

Whoops, Precision 165
I will just top off and carry a 4 gallon with me.
Excellent point. Thanks!
Agree with all about the rediculous new gas cans. I hate them and pull the anti-spill guts out of the nozzle right away upon buying one.

I just didn't want to run out of gas and have over a mile to go back to the marina down the canal. I would feel really bad in asking my wife to get out and swim while she was dragging the sailboat with her. :)

Now I have to find the mixture for this thing online somewhere. I venture to say it's 32:1. Hmmm, maybe I am off and it's 100:1--that's insane.
There's a kit to convert to a external plug-in tank.
SERIOUSLY? I would do that in a minute. 6 gallon metal tank in the open lazarette would be nice. Have any idea where these kits can be purchased? I can search but thought I would ask.
I know others will argue this point, but if you can find ethanol free fuel, it'll go a long way to preventing your fuel from going stale early (as well as finding a cap to seal off the tank). Honestly, if you are like me, you use the motor to get "out there" and to get back, and its only really used a couple hundred yards each way. The fuel in the tank will last you several outings that way. Top it off before each trip and the 2 gallon can is a "just for emergencies" kind of thing. 1 hour motoring works out to about 6 nautical miles (or 5 perhaps for the p165)... but still a good distance for a full tank. I wouldn't go crazy trying to retrofit a perfectly good integral tank outboard (which is less hassle than an external tank outboard)... use it a season that way, and then decide if you want a 4hp with external tank fittings. People love the fully integrated smaller outboards for their tenders, canoes and such so there is always an after market for motors that size.

I lean towards if it ain't broke don't fix it mentality with outboards. They create enough hassles ALL ON THEIR OWN, without help from us.
Agreed. I am just going to buy a few of these since my motoring each way is or could be close to 2 miles. I like the metal cans with the built in funnel. Not cheap but better than the plastic POS ones.
Actually it looks like I can't use the metal style for the height of my lazarette is only 8 1/2". I am looking at the new anti-spill plastic cans (link below). Has anybody tried these?

No-Spill Gas Can - 1 1/4-Gallon Capacity, Model# 1415 | Fuel Cans| Northern Tool + Equipment
I looked up the size of the tank at 1.4L. I would say you would push an hour of operation with a tank that size. How far you'll go will depend on how fast it will push you. I would bet you'll get the 3 mile round trip done, but not much more. Top off every time, prior to casting off.
Hmmm, 1.4 liters is .37 US gallons so a tank size of 1.4 gallons would give me almost 4 fills I believe. The tank is small on this motor.
The tanks are small on all motors of that size. Usually between 1.0 and 1.4 liters.

Not following how you got from 1.4 liter tank on the motor to a 1.4 gallon gas can?
1.4 liters is equal to .265 US gallons according to coversion tables. Most small gas cans including the one I will buy is 1 1/4 gallons which would then be equal to about 4-5 tank fills if the outboard gas tank is truly1.4 liters.
