Boat Motor Oil Ratio

Recommended Posts

Hello all...

Picked up my first boat with a motor last week - the motor is a 1983 Evinrude 25 HP. Might be a dumb question but I don't want to screw it up - what would be the correct oil/gas ratio? The back of the bottle says for most outboards dump the whole bottle into 6 gallons making it 50:1 - does this sound right? Of course all my extra gas cans are only 5 gallons! grin Thanks in advance.

plugs are cheaper and easier to find than a engine i would dump the whole bottle in.. little extra oil wont hurt anything ecept the plugs just replace once a year if you use it alot..

Hey Shoot... You could just switch over to Amsoil and run that. I have a '77 Johnson 35 hp on my pontoon that I've been running Amsoil in for 7 or 8 years now and the darn thing runs better than ever. The correct Amsoil for that, is called 'Amsoil Saber outboard 100:1 Pre-mix'. I just got tired of stinking like the exhaust, and always having to replace plugs after a weekend or so of backtrolling. Now, I replace plugs maybe every 2 years, more often than not, I just regap the old ones and put them back in. 'TheOilman' can tell you more, but I'll guarantee, Once you try Amsoil, you won't go back to "dinosauer oil". Phred52

I know i little bit out motors. but I have heard with sleds if you run them in a low idle (pulling kids on a sled). you run the [PoorWordUsage] out of the motor for a while and the extra heat is clean the plugs. but sometimes its a loss cause for some plugs that are too fouled. would that work?

i find that sled plugs stay clean at -30 like no other.. there is reallly no way to clean a plug other than to take it out..

do yourself a favor and get one of those oil mix measuring bottles. they are like $3 and are sold at all the stores you buy boating and or fishing stuff. I got mine at the place they wear orange shirts. It makes measuring out the oil simple. this way you can buy your oil in bulk and save money.

Shizzy is right on. The best thing about those bottles is that you can measure out more or less oil for specific situations and different motors.

Awesome....didn't know they made such a thing....been measuring it with one of my wifes old ounce measuring cups for years for the weed eater....guess this would make more sense. grin

I just might do that...I thought the exact same thing last night when I got in my truck after taking the boat out...stunk bad like exhaust and wondered how to avoid that. Thx!

    • Heavy rains across northwestern Wisconsin last weekend and early this week have flooded some roads and caused washouts on some highways, roads, state parks, forests and trails. According to the National Weather Service the area has received 7 to 12 inches of rain from Friday through Monday.Several park system property or portions of properties are closed due flooding. Amnicon Falls State Park, closed temporarily but has reopened, though some roads, trails and observation areas remain closed. Pattison State Park is open for camping only; all trails, observation areas, picnic and day-use areas are closed. There are washouts on the dam that forms Interfalls Lake and Highway 35 over the dam is closed. A campground and horse trail are closed at Governor Knowles State Forest and the day use areas along the river at Interstate Park are underwater.Water was roaring over Little Manitou Falls at Pattison State Park.Photo credit: Gervase ThompsonAll rivers in the region are running extremely high. The falls at both Amnicon and Pattison are roaring, but road closures mean observing the falls now is challenging. The Bois Brule and Flambeau rivers are high enough that some canoe launches and campsites are underwater. The water is making its way downstream and the Lower Wisconsin River is running very high with all sandbars submerged and canoeing and kayaking not recommended. The river is expected to crest Muscoda this weekend at 40,000 cubic feet per second. .
    • I'm still going to smoke this fatty while camping this weekend whether Leech likes it or not.....😋       See you fellers on Monday........
    • Rick didn't like all the "My Grills bigger and better then yours" posts!  😅
    • We switched to a new server. Had a glitch in our dB that lost a couple days of posts.
    • I ripped a hole in one of my favorite pairs of fishing shorts just need a decent sized patch to cover her up
    • I am not sure what happened either but we lost all of the posts last couple days not just this thread. And it looks like the same thing happened over on FM site as well. I know the site was down last night while I tried look at it.
    • We had no problems but only brought 10 extra gallons over.  We fished 5 days, pretty much running wherever we wanted and ended with 7 gallons remaining in the boat.  So, we burned 30 gallons of fuel in a 1785 Lund with 90 hp Mercury 4 stroke.   I thought that was pretty good!
    • Seems to me that we are missing an entire page from this thread that was here yesterday.... what gives?
