Re: Stus-List 35 MK III leak from Propeller log or strut
Most likely keel bolt threads corroded. Only way they could find good threads is by using washers. Surprised they didn’t suggest a more complete repair. -Rob Sent from my iPhone > On Jul 3, 2020, at 4:14 PM, David Swensen via CnC-List > wrote: > > > Wow. Thanks for the pic.

Re: Stus-List 35 MK III leak from Propeller log or strut
Wow. Thanks for the pic. I didn't realize it would be bedded that deeply. It is amazing how water will find a way. I was able to tighten and use WaterWeld, as suggested, but unfortunately, the strut was not the major contributing factor to the water intrusion. The aft keel bolt is leaking. It is curious as to why there are 10 stainless washers on that bolt. PO said she had the keel rebed 5 years ago, and that is what they did. Maybe they tightened it too much, and sheared it from the lead keel? I am having it hauled this coming week to have a pro take a look. It may be beyond my pay grade at this point. Happy 4th!

Re: Stus-List 35 MK III leak from Propeller log or strut
Price? WaterWeld is about $6 for a 2 ounce tube. I know it works. I discovered a small leak below the waterline last year while working near the rudder tube. Probably coming from a defective layup around the tube. Slapped some WaterWeld on it. Hasn't leaked since. I keep a tube of WaterWeld on the boat. I've used MarineTex but never below the waterline. -- Dennis C.

Re: Stus-List 35 MK III leak from Propeller log or strut
Yep, those 4 bolts are most probably the strut bolts. No big deal to drop the strut a bit and re-bed it once you haul out. Until then try to tighten them. As I am a bit pessimistic about successfully stopping the leak by tightening the bolts, go to an auto parts store or a big box hardware store and get a couple tubes of WaterWeld. https://www.amazon.com/J-B-Weld-8277-White-Pack/dp/B000BRQ0TW Work it up per instructions and apply it to the leaks. At first it won't seem like it's sticking but keep working it onto the leaks. After 8-12 minutes it will finally stick. Now you can finish your season. At haul out, you'll have a bit of work removing it but then you can fix the strut. You may have to re-fair the strut after you re-bed it depending on how speed oriented you are. Dennis C.

Re: Stus-List 35 MK III leak from Propeller log or strut
Hi David Ah, the surprises of a new (old) boat. Good times. Mine was leaking seacocks. Probably worth trying to tighten the bolts for the strut while still in the water, I would. I don't see it making anything worse. Best access to that strut area would be to shut off the port cockpit drain seacock and pull off the hose from it, this will allow you to get back in there without as many contortions (but still not a good time). I've spent quality time in there installing the autopilot, and also had the strut off. If the bolts stick up enough it would be worth gently grasping the exposed end of the bolt to prevent it from spinning, and tighten the nut using an open end wrench. And if the engine is a 3GM it is my understanding that a fair bit of shaking isn't unusual at low RPM, mine is fairly annoying at < 1000 RPM. It is OK at 1200 and up though.

Stus-List 35 MK III leak from Propeller log or strut
My new to me 1985 35 MKIII was launched a week and a half ago. On the trip from Newport RI to Salem, MA last weekend, the bilge pump was getting a periodic workout. The water pump was leaking like a sieve, so as soon as I could I replaced the pump ( seals to bearings was toast so beyond rebuild). I thought my bilge pump could rest. Not so. It is still going off every 5 -6 minutes, just for a quick burst, removing maybe a cup of water. After a sleepless night last night, I paddled out to the boat this morning and traced the leak to behind the propeller shaft log. There are 4 bolts that I could see after contorting myself behind the fuel tank. I assume they are mounting bolts for the strut. These bolts were wet and showed some corrosion,and were the apparent source of the stream of water legging under the engine and eventually to the bilge. The PO claimed the boat was bone dry (Not so said the boat yard in RI). The surveyor did not pick up on anything in this area. The boat had been on the hard for 2 years. I have a feeling this may be a short season and I will likely need to haul the boat to repair. Has anyone had this problem? Engine mounts are in need of replacement, too.
