Hi guys my 87 prostar 190 has a bad leak where the drive shaft log penetrates the hull. Any ideas on how to repair? Has anyone run in to this problem before?

Well, the normal path for water into the boat there is through the packing around the driveshaft, inside the big-ole brass nut just below and out of your picture. That's a normal maintenance item and easily adjusted. Are you sure the water isn't coming in there?

If it's actually coming through some kind of break in the fiberglass, I can't help you. You'll probably have to get someone knowledgeable to decide if the crack is a structural problem, or something simple that a patch of fiberglass and a spot of resin will take care of.

So, I guess, the first problem is finding exactly where the water is coming in.

+1 on Frank's comment.... a video or more specifics where the water is coming in. If it's a bad shaft log it can be replaced. It could be as simple as needing new shaft packing... where is the water intrusion originating? - some water is normal... a few drips per every 10 seconds ok. or you can get a dripless packing.

The water is coming in through the fiberglass. I'm very familiar with replacing shaft packing but unfortunately that's not the issue on this one. The boat is at creative fiberglass now (a local shop) and will be ready next week. I'm not a fiberglass guy and figured I would leave it to a skilled hand because we are looking to start skiing in the next couple weeks. I will post pics of the repair when I get it back. Thanks guys!

Looks identical to my '89. In my case the solution was to remove all the glass on top of the shaft log, reattach the log to the hull with epoxy and glass over the whole assembly. Took 4 -6 hours and it's been working great for several years.

What's up mike!? Haven't heard from ya in a while.. The repair is gonna hit me for 250.00 and that was a big deciding factor for me because I'm currently out of epoxy resin and mat so I would've had a good bit in materials if I bought the west system stuff because they are very proud of it u know. So he says I should have the boat back next week and I will post the repair pics.kinda wish he would send me some progress pics.

Not at all. And I've seen his work. There is a guy on a local lake we ski on that hit a log and ripped his rudder off leaving a huge hole in his hull. This guy repaired it and did a really nice job for 600.00 so I'm optimistic about it.

My '89 is doing the same thing, I bought the West Systems materials this summer but never got around to fixing it.

I should replace my shaft log, it's been there since new and while I'm at it might pull the shaft and replace cutlass bearing too.

You may not have to replace the shaft log (it's not a part that wears) Dropping the shaft and replacing the cutlass bearings is a good idea. The shaft may get in the way of this repair anyhow. Especially if you have the Powerslot transmission.

Ok so my OCD was getting to me and I picked the boat up at the fiberglass shop yesterday. After all I've done to the boats I've restored it made no sense to let somebody else make this repair. I got started on it today and will post pics of my progress. I got the log cut out and all old fiberglass removed. I cleaned the surrounding area really well and have the log epoxied back in. I will lay the fiberglass mat tomorrow. All is going well!!

Boy, does that look familiar! I was a little intimidated by the job at first, but it's not that bad once you get into it. I used polyester for the final glass work, but I think epoxy might be better. What are you using?

Tph I agree 100 percent! I kinda freaked out at first that's why I took it to the fiberglass guy but this job really hasn't been bad! I'm using epoxy on the entire job with high density filler added to bond the log to the hull.its going really well!

How did you get the log off? did you just cut around the edge and pry it off?

Mike after I ground the fiberglass mat around the log off it lifted right out so im guessing the original adhesive had deteriorated and that's why it was leaking water.

Yea I don't know what kind of adhesive was there originally but I epoxied it back in with a thick bead using high density filler in the epoxy resin mixture. It should give no more problems.

I may have used the wrong term - I was referring to the hose section from the log to the packing seal. Mine is looking pretty bad.

I do have the Powerslot, so not quite as much room to work but still a pretty easy repair. I replaced my packing last year with the Gore material, very satisfied with it. Just a slight drip but the shaft runs very cool.

Thanks for the documention, always good to have pictures!

Oh yeah. That hose was looking very poor on my boat as well. I replaced it when I dropped the shaft to do the bearings.

This is a job I've been putting off...

Since I use a lift I just run bilge to clear water, but I get a good leak around that shaft log.

I was initially hoping I could pull the shaft and pop the plate out, slather in 5300 and shove it back in place, but I think I'll have to go whole hog.

reftech
03-12-2013, 07:02 AM
Yeah there's really no way to band aid the leak because it originates under the log plate which is covered by the fiberglass mat. So u have to go all in to fix the root problem. Just my 2 cent :)

Reviving this thread from a couple of months ago as I started on '89 PS 190 today. What better Mother's Day present than getting the boat ready, right? The fiberglass covering the shaft log was easy to remove, and obvious water was entering between the aluminum log and the hull. My boat has the Powerslot and there isn't enough room to move the log/seals, etc forward and access the area in order to re-attach it properly and re-fiberglass.

So...it looks like I need to remove the coupling and will do the cutlass bearing while I'm doing.

The coupling nut looks like 1-1/4"? Guessing that as my 1-1/8" socket was too small. Pretty sure I can secure the coupling with a pipe or strap wrench. I've read the 'how to' on using a socket and getting some longer bolts to allow the coupling to free from the shaft. And, when reinstalling, how tight do you tighten that sucker?

I will post up some pictures later on.

I'm debating whether to reattach the shaft log by bedding it in a layer West Systems G-Flex epoxy or using 3M 5200. Once it's bedded in, I will cover the shaft log with G-Flex resin and glass mat. I've worked with epoxy and mat in the past on lots of boats, but first time for some of the other stuff. I don't have a lot of 'spare' time so I'm looking for some tips to keep me from having to re-do a step or three:)

So, bed it in G-Flex or 3M 5200? ......And I'm open to any suggestions and tips on removing the coupling and prop. Everything is soaking in PB Blaster right now.

Thanks in advance,

Jack

FrankSchwab
05-12-2013, 05:26 PM
Well, 5200 takes a week or more to cure. If you're planning on skiing soon, I think I'd suggest epoxy. But, I'm not an expert.

05-12-2013, 06:08 PM
Thanks Frank, I'm at least 3 weeks away from using the boat, so drying/curing time isn't an issue (yet). Looking at it closer, it looks like the aluminum shaft log on my boat was set down on a layer of Bondo. It's pinkish in color, hard - but you can chisel into it. I'm guessing that was put down to account for the slight V-shape of the hull and the flat surface of the aluminum log.
Bondo?
