Mercury Outboard 175hp help!


friskylizard

Question

I have a '89 mercury 175hp that has been to the mechanic 3 times. When i first start it and run it for about 5 minutes under load its fine but as soon as want to go full throttle it only pulls 3100 rpm for about 30 seconds and then drops power and the engine dies. But, every once and awhile it will go full power and get up on plane like nothing is wrong. confused.gif The fuel line is new, there is spark on all cylinders and i have a new water/fuel filter inline. Has anyone else had this problem??

I had a problem with gasline bulb on my boat once where if it was either flat or angled the wrong way the little back flow check ball would not allow enough gas through to run full throttle.

Everything stated so far is good stuff to check...

Did you stabalize your fuel system before storing it over the winter? It almost sounds like a carb cleaning might be in order...

And if you've had it to the mechanic three times why haven't they figured it out yet?

Thanks for the input.

UpNorth - what did you end up doing?I do have a new bulb/hose. The gas tank was drained for the winter and it does have seafoam in it now. I should say that i took it back to the mechanic and also made him do a "check-run" with me after he pulled the plugs (checked for spark) and pulled the jets. Of course when he was in the boat it got up on plane.

Was the motor run until it died, meaning that the carb bowls were empty? Seafoam helps, but if your carbs are gunked up bad it won't quite do the job.

I had the same problem 2 years ago when the local boat dealer put on a new gas hose. They put it on backwards. I didn't realize it at the time but there is an arrow on the hose that points in the direction of the gas flow. It was backwards. I switched it around and the motor worked great.

I just cut the hose so that the bulb, when put on with gas flowing the proper direction was slightly slanted down from the motor.

      I'm not there, so I can't tell exactly what's going on but it looks like a large area of open water developed in the last day with all of the heavy snow on the east side of wake em up Narrows. These two photos are from my Ring Camera facing north towards Niles Point.  You can see what happened with all of snow that fell in the last three days, though the open water could have been wind driven. Hard to say. .

      Black Bay had great ice before but a few spots near rockpiles where there were spots of open water. It looks like the weight of the snow has created a little lake in the middle of the bay.

      On the south end...   Thanks to some cold spring weather, ice fishing continues strong for those still ice fishing.  The bite remains very good.  Most resorts have pulled their fish houses off for the year, however, some still have fish houses out and others are allowing ATV and side by sides.  Check social media or call ahead to your favorite resort for specifics. Reports this week for walleyes and saugers remain excellent.   A nice mix of jumbo perch, pike, eelpout, and an occasional crappie, tullibee or sturgeon being reported by anglers. Jigging one line and using a live minnow on the second line is the way to go.  Green, glow red, pink and gold were good colors this week.     Monster pike are on a tear!  Good number of pike, some reaching over 45 inches long, being caught using tip ups with live suckers or dead bait such as smelt and herring in 8 - 14' of water.   As always, work through a resort or outfitter for ice road conditions.  Safety first always. Fish houses are allowed on the ice through March 31st, the walleye / sauger season goes through April 14th and the pike season never ends. On the Rainy River...  The river is opened up along the Nelson Park boat ramp in Birchdale, the Frontier boat ramp and Vidas boat ramp.  This past week, much of the open water skimmed over with the single digit overnight temps.   Areas of the river have popped open again and with temps getting warmer, things are shaping up for the last stretch through the rest of the spring season, which continues through April 14th.   Very good numbers of walleyes are in the river.  Reports this week, even with fewer anglers, have been good.  When temps warm up and the sun shines, things will fire up again.   Jigs with brightly colored plastics or jigs with a frozen emerald shiner have been the desired bait on the river.  Don't overlook slow trolling crankbaits upstream as well.   Good reports of sturgeon being caught on the river as well.  Sturgeon put the feed bag on in the spring.  The bite has been very good.  Most are using a sturgeon rig with a circle hook loaded with crawlers or crawlers / frozen emerald shiners. Up at the NW Angle...  Ice fishing is winding down up at the Angle.  Walleyes, saugers, and a number of various species in the mix again this week.  The bite is still very good with good numbers of fish.  The one two punch of jigging one line and deadsticking the second line is working well.   Check with Angle resorts on transport options from Young's Bay.  Call ahead for ice road guidelines.

      With the drifting, kind of hard to tell for sure, but I'm guessing about a foot and still lightly snowing. Cook end!

      How much snow did you get on Vermilion? 
    • Mike89
      lake here refroze too...  started opening again yesterday with the wet snow and wind...  very little ice left today...
    • Hookmaster
      A friend who has a cabin between Alex and Fergus said the lake he's on refroze. He texted me a pic from March 12th when it was open and one from 23rd when it wasn't. 🤯

      I don't think that there has been any ice melt in the past few weeks on Vermilion. Things looked like a record and then Mother Nature swept in again.   I'll give my revised guess of April 21st
