Bent prop shaft (?)

7 posts in this topic

I let the girlfreind use my boat to entertain her folks this Summer. An hour after they got back, her 6 year old nephew came sneaking up saying "you should have seen what Anne did to your boat". Apparently there were some "big" rocks close to the landing (funny how GF forgot to mention the confrontation of my prop and the rocks). Yup, I replaced the prop and noticed that it had a little wobble to it -- maybe 2-3mm when it was spun. I used it a few more time this Summer and didn't really see any performance issues. Does this need to be taken care of? How much to straighten a shaft? shocked.gif Also, does a guy even have a chance if he suggests a reimbursement from the GF? crazy.gif

Sadly, I've been in your shoes. I forget the tolerance, but I would say if you can see the runout, then you need to fix it. It will run and push the boat along, but the added vibration will damage your motor in the long run. You might be able to straighten it....might.

I ended up finding a used one on ebay and having a tech install it for me. Saved quite a bit as the part alone is big bucks frown.gif

He had no problem doing that for me and I could provide his name if you are interested, (lives between Jordan and New Prauge).

Good Luck

dtro is correct, you better have it taken care of, you could have the shaft seal damaged, it will let water into unit and damage it severely. Ebay is an option, otherwise you can straighten it up if it's just a little bent. You will need a mechanic to remove it and install it. I too know a guy that works as a tech for main dealer and does some sidejob, very reasonable but it's south of the metro.

Even if you decide not to fix the bent shaft this year yet be sure to get the lower unit lube changed... if it's bent it could be bent far enough in to screw up a seal and let water in... and frozen water in a lower unit = trouble in the spring...

Good Luck!

I had a tweeked prop shaft, and it took some sort of a diagnostic machine the dealer had to indicate the problem. It was the most expensive part when the bill came, $600. I was told a prop shaft cannot be repaired. I don't know, but makes sense. Any wobble and you'll have problems, mainly with seals and overall performance.

I hope you have insurance on that motor. It's likely covered for hitting an underwater object.

Ya, I do have insurance on it...never thought about that...a $350 deduct though. And I did the lower unit grease job this Fall and didn't see any water in it...yet. I talked to a guy at "boat motor salvage" and he said he could do the job--straightening it--for ~ $200. I assume this would cover un/install. Should probly have new seals put in at that time too.(?)

Those shafts are pretty short and stout, I really don't see how you could accurately straigten it. I would think he has one that he could swap out.

      Drove all the way up to grindstone this morning from Forest Lake. As I'm driving along the shoreline, I can't stop admiring how beautiful of a day it is, and how great it will be to be on the water. Was totally amped up to fish for some trout! Then I pull up to the boat launch...and it's closed down! :mad: This dredging project has been pushed back for years, then they finally decide to do it on a beautiful sunny day, that I picked to come here...on the last day of the lake trout season nonetheless! Needless to say, I was very upset! 

      Could have throw a line off the south shore since you were all the way up there. :(

      Hey guys thanks for the tips.  What you are saying really makes sense.  I have been working on these items this week, not expecting a completely changed dog out there but looking forward to continued exercises this weekend out in the blind.

      I bet the state, not the political cronies, would get a lot more money by having the auction on the internet or allowing phone bids.  Heck, put them on the bay of E. 

      Actually DMV and DNR do quite well at their auctions. You win bid, You Pay, You own. No red tape, no collection process, simple and things seem to sell for quite a bit of money. Go and one see for yourself, its quite amazing. Lots of them at the Arden Hills DMV. Hard to collect money over the phone and on the internet. I do believe they will use the same auction process for this property sale as the DMV and DNR are good at it and a lot of buyers will be there. If the internet were to be used, the "political cronies" would need to create a bill, Ear Mark several million to develop a site, create an app, hire 40 to 50 people to manage and than increase taxes to cover the cost much like Obama Care Not a good plan. If your interested, go to auction, bring lots of money, win a bid and own.

      They were dredging there today. Not sure if they are done or if it will take longer.

    • the weather has not been good this past week either, but fishing was still do able. Pike island is a popular spot and I am sure you can find fish there. Gold is. would be worth a try as would the area around the wolf pack. We had 4 nice walleye today and a great fish fry tonight. Heading home in the morning for the season. so good luck

    • I bet we will end up going to red trying to convince the couple guys that dont like sleepers for some reason that a 10x24 sleeper is just like a cabin and that we can bring 2 portables to bounce around if we want. Dont really need a guide ill probably allready have gone there 3-4 times before this trip.... Maybe superior will freeze good this year and I can convince them to go there i guess I just get kinda bored or red sometimes

      Well, got out of the hospital and rehab a couple of weeks ago, Its been a long haul went in on Feb 15, with some massive heart attacks.   Starting to feel better and have hit Fish a couple of times.  Thought I would check out the site and see if traffic has picked up,  Sorry to say not much different, a lot of lookers as usual and not a lot of posters

      Been there and done that.... Not the site but the hospital etc

      In northwest Wisconsin 26 hunting dogs have already been killed this late summer.   Already breaking the record of 23.  Be careful in the northland.
