Potential lower unit problem

Question

Heidi

A "friend of mine" drained the lower unit gear oil in his

1980 50HP Johnson motor last fall. My "friend" put about 10 hours on it this summer. My "friend" went to change the oil Sat. and to his surprise, the lower screw was loose and about a half cup of lake water drained out. My "friend" never went back to finish the job and forgot to replace the lower unit fluid. "He" said the motor ran fine this summer.

I, I mean my "friend", put new fluid in this weekend, but is worried about the lower unit rusting or giving out. Any ideas on what could be done now, or does my "freind" just hope for the best. Thanks for the replies.

If you jusdt used it 10 hours it shouldn't be a problem, but rust would be a concern.

Since water is heavier than oil it will sit on bottom, you have approx 1/4" of room before touching bearings or propshaft. If motor was sitting upright it shosul be no concerm, if it was tilted it could be a concern, but only time will tell.

If I was you I would just replace lube completely, run motor on muffs, shift it in gear (BE CAREFUL) and run it for a while to be sure all the oil has coated the exposed parts.

That's it. I don't think you (your friend) did any damage, and if you did only time will tell. The alternative is not pretty, a rebuilt lower unit will cost more than motor is worth.

      Those were caught from a shallow lake (17’) in 9 feet of water at the bottom of the first shoreline break. I was using a UV buckshot and minnow head since the water was murky. The crappie is still swimming the walleye not so much. I didn’t get the exact location. Sorry

      Hello from the NW Angle!

      Minnesota fishing has been most productive in 20-24 feet of water.  Guests are bringing home their limits of Walleye and Sauger with the occasional Perch and Northern mixed in. Fish have been most active early and late in the day and the bite has been terrific. The use of electronics continues to be very beneficial with fish taking jigging spoons, jigg’n raps or rattle baits.  Snowmobile ttrails on the Minnesota side continue to be maintained and are in great shape. We are still making ice, with most spots at over 30 inches. 

      North and East of us in Canada, big Crappies are coming in on light tackle setups out of 30 feet. If you are looking for walleye, they are everywhere!

      Until next week, 

      Sunset Lodge

      On the Bayfield side of the bay, the target depth is typically 10 to 40 ft. The basswood island area is where they go after lakers. There’s a plowed road that goes out there. As of last week the ice was about 20 inches in that area, might be thicker now. Check out the Bayfield webcam, you can see what kind of activity is going on.

      Wanderer, stop in at the River Rock bait shop in Ashland and they will get you pointed in the right direction.  They are always pretty cool about that.  Fishing near Ashland off of 2nd landing can be good.  Don't need nothing more than regular walleye gear, and some tip-ups and really there is no rhyme or reason where a guy should set up shop. Its a pretty wide open water and the fish that live there are always on the move. For us, most often, the sit and wait pays off.  It has been slower as of late, but still some fish..  Good luck, JH

      Anybody know if there is a pressure ridge/ice heave out in front of the Warroad Access? I know ice conditions will change throughout the coming weeks. Looking forward to getting after some pike.  The last few years there has been a pressure ridge there, last year it went from Springsteel over to Swift. And we've been up there plenty of times when there hasn't been one at all. Just curious to find out what conditions are like in that bay. Thanks!

      Most likely our last trip up this year unless we go up for crappies but i'm running out of weekends. We had another great trip this weekend the fish are so fat this year more than I remember in the past.  Got my old man out for a good walleye bite he had a blast and caught a ton of fish. One day they just attached the bait as it was coming down they would come up and smash. Next day you put in the bottom and not even see the lure on the vex bring up a tad and they would smack it. Fun and a lot of snow hitting yesterday when we left.

      Switch to regular Budweiser and they seem to just jump out of the hole. No, seriously the way I improved my landing success through the ice was to go to small treble hooks. One small one on a 6' leader, a weight and Colorado blade above the leader seems to work for me. If you are on the flag right away, you don't risk gut-hooking them. I also recycle my Power Pro musky line and put it on tip ups. Also, I should add that I always  have a jaw-spreader and 8" forceps for quick and easy hook removal.

      Funny...seems like when the Emerald run slowed down up there 4-5 years ago, the fishing followed suit!
    • anyfishwilldo
      they only ran for a couple days.  They have them on the canadian side but its illegal to transport live bait across the border
