Issues where prop shaft exits hull - see pics

groundhogyh · Sep 10, 2016

The shaft comes out at an angle. It is not straight out of the back of the boat.
This is due to the prop shaft having to miss the rudder shaft (which is in the center) as it goes by.

Yes, obviously. That's not what I was asking at all.Do you not see the shaft exits at a more downward angle than the angle of the hull? Do you not see the buildup of what appears to be epoxy putty, and that the putty buildup is about 1/4" thick at the top, and tapers to zero at the bottom? To fill the gap caused by the difference in the two angles?And you DO see the cracks and the gaping holes in the hull, right?Please tell me if my question is unclear, I will try to rephrase it somehow.

sorry i didnt answer properly. i dont see any of your pics. i think on this particular yahoo group, you can not attach photos to email. there is a way of showing pics, but it involves links. if you go to the group page, i think you can find or search for photo instructionsghSent from my iPhone

LOL ... yeah, Yahoo groups leave a lot to be desired! Very 1995-ish. I really wish there were an actual discussion forum for the Vega community.Anyway, there is a link at the bottom of my first post that should take you to an album I just created. The link shows up on MY screen, at least. The album is called "PROP SHAFT EXIT".Is the link not visible at your end?

Speaking of links, let me try to post another one. This one (hopefully) takes you to a pic from a user named "lewills30", who appears to have done the repair I will need to do:Yahoo! Groups

Repeating the link: Yahoo! Groups haven't replied as I didn't understand what I was seeing. For example, in IMG_0154, I see curves that I can't relate to my Vega, and I see what looks like wood that puzzles me. Perhaps a picture from a distance for perspective and one or two more pictures getting closer or zooming in would help.Alan

My boat is on my trailer and looking at it, seems like your shaft is more at a downward angle. I am and aircraft inspector so I might not be the best person to consult on this matter. However, there is does seem to be some damage to that area. First thing I would do is check your prop shaft to transmission alignment. Mine was all effed up and had to shorten my engine mounts to make a reasonable fit. My shaft was actually rubbing on the shaft log. My engine was a retro fitted Yanmar 1gm10. If that is not the issue I would check to see if the shaft log was installed correctly at the factory or has in the past been repaired. Remove your cutlass bearing housing and build up the area with epoxy/glass to reinforce it properly. That is not too difficult. I think if you go thru the photo albums you can see and example of one previously done. Best regards....Tim M

Hello , first of all dont panic. It can be done as good as new. I have just gone trough the same repare (took me a long time) , which left me very satisfied for the condition of my repared boat (allthow i sufer from perfectionalism) , very sure about its stuctural integrity and a relatively "mastery" of epoxy jobs with WEST SYSTEM. It was dificult only phsycologicaly. Seeing your pictures , i bet you have same problem at the line where the two half parts of the boat hul are merged together , all along the ruder shaft hollow edge and under the keel. be sure to check these areas. I ll get back to you with details in a more convinient time for me, to give you detailed answere , as needed.... Dont worry , it ll be fine. ???: "gene_neill@...

I'm pretty sure there is some extra work coming my way when I replace my engine next month. To my untrained eye, it looks like the shaft was installed out of alignment (at the factory?). Epoxy putty appears to have been smeared around the area, and there are some serious-looking cracks, the extent of which is not know yet, but the pics show it all pretty well. I have some thoughts on what may need to be done, but first I'd like to hear from some of the sages!Anyone who has experience in this area, would you please take a look and give me your thoughts?

Now you've made me panic! LOL Okay, not really ... but I will look forward to hearing more from you sir, thanks. I don't THINK this problem extends more than 4" (10cm?) forward, but I will certainly examine things very very closely.

I had to rebuild my shaft tail section also. Very simple. I posted pictures in the group under SV Lilly Too, It isn’t what you think, the tail end is resin and sand, it is very easy to fit.

Resin and SAND, you say, Larry??What did you do, just grind away the damaged material and build it back up with thickened epoxy or something? It looked really great when you were done!

Hi Gene,

Cut the damaged material totally out so you are looking at the resin sand mix. Once you have this clean and squared up a little , drill some hole back into the resin sand mix. This will give you a key way for the epoxy to grab onto. Go back into the existing material about a ½ - 1”. Drill 3/8” dia. Holes allows epoxy to be forced deep into the tail section. Warning only drill into the resin sand material...you don’t want to drill the prop shaft tube , could be a little problem if you do. See easy as pie. I pulled the prop and the coupler bearing off so I could get into the resin sand, don’t worry about the bronze housing that the couple bearing bolts to. I replaced mine, but you can clean around this so the new epoxy bonds to this housing as well. Shape it to your liking and bolt everything back together. Poof…done.

Thanks Larry, that's very helpful! It doesn't look like an intimidating job, provided the cracks don't go back further than they appear to.Any tips on removing the prop? I guess that's the next step for me, especially since she's getting an all new drive train anyway. My guess is, spin off the big bolt at the aft end, but since I don't have the correct wrench and I don't know which way the threads go, I actually have time to ask before I do anything stupid. LOL

 Last time I removed my prop (not the original Vega equipment) the steps were:-          Remove the split pin and castellated nut and remove the KEY (the easy bits)-          Next I used a hub puller, blowtorch and a big hammer .. lots of heat, banging and tightening of the hub puller until it jumped free.  The prop had been on about twenty years so was on pretty tight.      From: AlbinVega@yahoogroups.com [mailto:AlbinVega@yahoogroups.com] Sent: 12 October 2016 20:05To: AlbinVega@yahoogroups.comSubject: [AlbinVega] Re: Issues where prop shaft exits hull - see pics  Thanks Larry, that's very helpful!

Here is my prop. A far as I know, it's what the boat came with in 1979. It supposedly works, but it's getting replaced regardless: Yahoo! Groups
