Outboard engine problem...heLP?

5 posts in this topic

My brother has an older, '90 something lund console with a 40hp outboard engine(not power trim/tilt). When he is going full throttle/max speed, it keeps making multiple jerks. Anyone know the cause of this? He has not brought his issue to a small engine mechanic yet but I do know that his motor should be good, rebuilt new I believe. Also has anybody in here tried to put on a power trim/tilt kit and how good is it? Worth buying? Any info would help. There's lotta good people on this website with awesome skills and experience. Thanks.

The motor jerking along sounds like a fuel delivery issue. couple of things to check.

First, check the fuel line from the tank to the motor. If it is kinked at all, it will starve the engine for fuel (had this happen on mine).

If not there, Check the fuel line itself. many times the priming bulb can go bad and not allow fuel to pass as needed.

Finally, check/replace the fuel filter. Many times this little item is neglected and is the cause of many poor running motors.

this is just a start though...Inexpensive and easy to do..then test again.

When you say jerk is this a loss of power or does the moter keep reving? If its a quick hard jerk(sounds and feels like the transom is going to be ripped out) I beleave its slipping out of gear.Check your shifting adjustment it may have came loose and moved a little!

Sounds like worn clutch dogs in the lower unit. Sometimes the clutch and gear dogs can be resurfaced by a machine shop for a fraction of the cost of new parts.

      How do you even get on this lake to ice fish?  Seems to be surrounded by Private land.

      Well Friday was a little slow picked up some nice gills here and there no crappies. Sat morning picked up a couple 10 inch gills and a couple more for the bucket here and there. Sat night 930 the crappies came through I caught 17 biggest was 12. Sunday picked a few more gills up for the bucket before heading off to a different lake for walleye. again fish wanted nothing to do with minnows only caught one with them. All other fish caught on a tungsten orange and green glow tipped with only a wax worm.   we were in 12 fow the sunfish were 2 off the bottom crappie cruising 4 off bottom Side note tried walleye tonight missed 3 of them! Now I remember why I don't walleye fish much stupid things

      I had the showdown as a hole hopping sonar but found I used my LX5 a lot more.  I went to the 7 and did not like it because it was bulky and hard to get used to both hopping holes and room inside one man Frabile.  Sold the 7 and bought another LX5 and do not see me going back to any other.  I have a wheel house and found is the only time I used the 7.  If you do a lot of fishing outside and like to move around.  I would stick with the 5, I now own two of them and don't see me using anything else.

      I'm thinking the opposite could be happening. Some people are doing fairly good and they are not saying anything. Last year a person I know did real good over 1 mile from anyone and called one friend with the coordinates of where to meet him in 2 days. He got back in 2 days and found over 30 wheelhouses right on his coordinates. His one friend that he told had then told another friend who told another friend and on and on. The key to ice fishing URL has always been to stay away from the crowds but now a good report brings in a crowd. Some of the business have decided that fewer fishermen having good fishing could be a better long term plan then many fishermen having poor fishing so they are not reporting good fishing.   Me, I think the fishing this winter is far better then last winter. Most of the people fishing URL now learned to fish URL by going deeper and deeper for the crappies. Before the crappie boom very few fishermen went deeper then 10 feet of water for walleyes. If we got into crappies or perch we knew we were too deep for the best walleye fishing. Most of my fishing this year has been in 8 feet of water or less. But also I'm standing outside and not sitting in a house. On URL you will usually get 4 or 5 times more fish standing outside or in a portable then you will in a house. I think it is from the noise or vibrations. shaky and Doc could set their house in 6 feet of water and do very good but they fished very quietly.  When fishing they had no radio or TV turned on, no generator, stepped softly and talk in whispers,,,,and they caught a lot of fish. I've sat with a camera and watched walleyes spook away when the heating stove ignited, when I dropped a rod on the floor and when I slid a chair across the floor. That is why all of our rental houses had a rubberized floor, to dampen the noise. Every year more and more people are fishing in houses rather then standing outside or in portables and I wonder if that isn't going to change how many fish are caught for each hour of "fishing pressure"/angler hours.  Sure it is nice to sit in a warm house watching TV while fishing but at least on URL I think you will also catch less fish. It will interesting to see if the DNR creel census starts to show a lower catch per hour as the percentage of people fishing from wheelhouses increases.
