Does anyone know much about lower-units? Mine is knocking but I can still go wide open without any affect on my speed. I haven't ran it since, and don't plan on it. My guess is a support bearing, but any info would be great. Does anyone know anything about costs???

If worst came to worst it would cost about $3,200 for a used lower unit installed.

Bring us up to date on the year, make and hp of your motor. Are you talking about the bearing under the impeller housing?

Wait till you get my age, then you'll really have trouble with your lower unit. Oh wait, someone just told me you're probably talking about an outboard motor.

Sorry, nevermind. grin.gif

It's a '99 OMC Evinrude Ficht, 200hp. I haven't taken it apart yet so I'm not sure what bearing it could be. I found shavings in the lower unit lube, but I don't think I ran it long enough to do significant damage to the gears.

I had shavings in the lube once on an OMC. Turned out 2 gears were damaged.

Completely re-built lower unit with gears, prop shaft, seals and labor was $1700. Prop shaft alone was $500 or so, and the most expensive part. If your prop shaft is ok I don't see a big repair bill.

You don't want to tackle that job unless you are a trained mechanic, it's not an easy fix.

I currently have my FICHT in for the same thing, complete replacement of entire unit and water pump rebuild while I was in there $3,100. Mine lower unit made two good growls and whamo all over in 30 seconds.

I have a 1999 Ficht 225, my lower unit went out last month in the middle of Mille Lacs (not fun). Anyway, it was a bearing failure that happened while running the motor, I heard a slight noise at first which rapidly progressed into a louder one then locked up the lower unit completely. A re-built lower unit with a 15 month warranty cost me $2,300.00. ouch!! mad.gif It was a bearing on the upper portion of the driveshaft , the pieces of that dropped down and destroyed the whole thing.

Tear it apart of have someone that knows do it for you, fix it right or it will get real expensive real fast if it hasn't already!

When I had my lower unit re-built the mechanic wanted to keep the boat/motor one more night after the re-build. He said the lower unit lube settles after each lube change, and you must double check the level after 24 hours.

He said if he had a dollar for every person that did not do this, and burned their upper driveshaft bearing...he would be a very rich man. He said the OMC's were notorious for this...the lube must be completely FULL, almost overflowing out of the top hole, to lube that upper main bearing.

So now, after every change in the fall I double check, then check again in the spring....and throughout the summer. smirk.gif

Sounds like a terrible ordeal you guys have...

Not sure but I guarantee it's cheaper than a lower unit!! Don't know if you plan on doing it yourself or bringing it in, but hopefully you caught it in time. I had no time with mine, all in a matter of 10-15 seconds.

I asked my father who was riding shotgun "does that motor sound funny?" Before I got the words out it was all over.

      Yes indeed. We actually bought it together. We wedged the pontoon boat into that lift last fall and hoisted it out of the water. Unfortunately the water came up so much this spring, the pontoon couldn't float with the rising levels. There wasn't much that we could do opening weekend except wait for the water to drop and then assess the damage. It's mainly a garbage hauler so no big loss for a $500 boat/motor.

      I forgot to post this but I got a jake during season B north of Princeton on some private land.  I had been hunting this flock of birds for 3 seasons now.  I hear and/or see them every day, but simply could not get a legal bearded turkey to come within range.  Finally, a hen came walking out with a jake and I dusted the jake on the 4th day of my hunt.  There's plenty of birds there, including several mature toms, so I intend to keep hunting there in the future as long as I can obtain permission.  The weather was downright terrible.  I had one nice morning of sunshine and then it was windy, rainy, and raw for days.  Saturday morning even produced a heavy summer-type down pour.  I was so thankful to be hunting in a blind.  I also saw a fair amount of other wildlife in four days, including deer, pheasants, a pair of raccoons, and a coyote.

      I have questions about the following hypothetical. Buy used boat and trailer from Iowa Resident. Would need to transfer, and I have not done before. Duck boat, may occasionally fish out of it. Technically 15'11 1/2" long. Will have motor. Do I need a title? Does it need registration?   Same for trailer. Need a title? Need Registration? License Plate?   Thank you for any help.

      I realize it's only been 2 days Raven77, but are you continuing to see the level decreasing?

      Sight fished this one, also got a 19" off a bed with a senko but didn't get a picture because my phone died. Length was 14" for the one in the photo. Haven't been able to get out much recently, but I should be able to go Saturday.

      Sizes caught matched most recent survey very closely - a lot of 12-14" fish with a few 15". Three to six feet of water against rocky shoreline at dusk was very productive. Fish still discharging milt. Should continue to be great fishing for next couple weeks along shoreline.

      Our group of 6 guys did pretty good. From Thursday evening to Sunday caught a bunch of crappies, 4 walleyes that were to big, a handful of pike and sunfish. One sunfish was 11". All on the west end.
    • ReefWhooligan
      You did a lot better than us...  Did you mostly catch them in mornings and evenings or were you able to catch them mid-day also?
