Bad gas?

8 posts in this topic

I'm having a problem with my '95 Yamaha 50 HP tiller. It will start, (after about 20 tries) but if I try and run it at more than an idle it will kill. Also it idles very ruff.

Last fall I put a can of sea foam in with about 1/2 a tank of gas (8-9 gallons) and sprayed fogging spray until it killed then put it in storage.

It’s seams to me that the gas is bad so yesterday I added 8 gallons of new gas and 2 bottles of Isopropyl alcohol. Then I took out a can on carb cleaner with me. After I got it running I spraied the carbs with the cleaner. Right after that it would run up to about 25 - 30 RPM's but it didn’t seam to have much power. After I slowed down it started to act just like before I cleaned the carbs. I did this 3 or 4 times and got the same results every time.

Do I need to take the motor in to get serviced or would draining the tank and getting new gas be worth trying?

Thanks of the help.

Let the boat set for a while. Try to get a hose to the lowest point in the tank and siphon it into a clear gallon container.
Let that container set for a while to let and water in there to settle. If theres any water you will see it on the bottom after an hour.
About cleaning the carb, all you did is clean the outside of the carb. Seafoam in the gas wont properly clean a carb either. Its got to be taken apart and soaked in a carb cleaner. Then all the jets and passages have to be cleaned out.

Do a visual inspection of hoses, wires, squeeze bulb. Replace spark plugs and fuel filter. If this dosent work I would clean the carb.

I'll give that a try. I forgot to mention that I put in new plugs also.


How hard is cleaning the carbs? I've done it on lawn mowers and wasn't too difficult but I'm guessing that an outboard is a lot more complicated

Did you take the Fuel filter out and dry it out? Empty the reservoir by the fuel filter and let the fuel filter dry. Check the plugs, and treat the fuel with OMC 2+4.

Then run the motor for awhile. You should notice impovement if fuel is your problem. That 2+4 is good stuff!!

To be on the safe side, I suggest new gas. 2 bottles of fuel additives and sea foam might be a little much for 18 gal of gas. It might not solve your problem (check the other things mentioned) but either way better safe than sorry....

Depends on how bad it is... if you have a vehicle with a remotely large tank (20 gallons +) put half in there and fill the rest of the tank up with good gas... most vehicles (pickup, etc) will run fine on old gas, as long as it's diluted.. it may smoke a bit more.. but it's better than dumping it on the ground I guess...

For my bad gas, I take a couple of tabs of alka-seltzer and feel fine in a hour or two... sorry, I just had to sneak that one in there.

    • I tried to purchase the screws yetti uses from Fastenal who is their vendor for the screws. They are only sold in large reels designed for a self loading screwgun. I finally called Casey at Glacial lake docks where I purchased my yetti and he sent me out the amount I needed. They work great to add additional fir strips. The plastic used to tie them together comes right off as you screw them in. Hope that helps. 
    • Sorry...was wrong on the specs.   Manufacturer is Core Ice.  It was 1450# for a 12' and 1250# for a 8'.  
    • I believe you want to use a zinc coated or galvanized steel according to the charts.  I'm sure someone will come along to correct me
    • In the back room there is a company that is using bonded foam panels (similar to garage door panels, but really clean looking), and had weights of 1250# for a 12' and 1450# for a 16'.  Aluminum trailer frames that could convert to a skid frame.  Can't recall the name.  I'm sure they were spendy, but I can see a concept like that going somewhere for the hardcore fishing crowd.   Yetti, Firebrand, Big Bite, and Glacier all had really nice display models.      Lots of campers (disguised as fish houses) out there at prices that make me want to jump into the business.  I was in two different manufacturers houses with prices well over $30k that had wire nuts for connections.  That is going to be a fun adventure for someone 2-3 years down the road when they find out their manufacturer saved $15 on their wiring.           
    • Thank you for all the help!  Ended up going with the Marcum VS485C.  After some research, there were a few other Marcums that were on the list (825 & 625), the Aqua Vu HD, and the Pan Cam.  The mini cams from all manufactures weren't what I was looking for, but they are cool and do have their place.     After seeing everything in person, I think the Aqua Vu HD had the best camera/screen.  The Marcums were a little bit behind, but the 825, 625, 485, and Pan Cam had similar real life clarity.  The 485 won out because of the $300 price point vs the others at $450-700, and was almost identical for resolution, other than the HD.
      I honestly think these cameras are all about 5+ years behind in technology in comparison to the broader camera/tv screen market.  Running off a 7-9ah battery is probably one of the limiting factors.  Another may be the cold.  The main reason (IMO) is that the manufacturers are hoping they can incrementally rape us by trickling out technology each year, similar to the computer manufacturers of the 90s/early 2000's.  For the price of a middle of the road underwater camera, I can buy a Chinese made 50" TV (these all have Chinese made 5-8" screens) and a GoPro or Sony Action Cam (which is 10x's the picture quality).
