Greenline: Diesel Engine Discussions

Now that we have a new, dedicated area for Greenline/Solar/Hybrid discussion, I thought I would start this thread with an eye toward aggregating diesel engine discussions (all models). Hopefully, this will make it easier for those that might be doing research in the future. Not sure if this type of "organization" will work or not, but will try and see what happens.

Anyone have problems with these? I just read the info sheet which said that it must be "lubricated" every 200 hours - the drawing showing only putting a bead of grease around the prop. shaft - rubber boot junction, without detailing how to get it inside. Also, to replace the unit every 5 years. Mine's 7 years old (owned 2 yrs.) and I've never done anything aside from checking for leaks. We're leaving on an ~800nm round-trip cruise down to San Diego next week.


Also, any problems with the shaft Aquadrive vibration damping system? Mine has thrown out a bit of grease, but never serviced in any way AFAIK. Factory photo below - mine's similar.

Hi again, PeterB40.

I had my shaft seal replaced around the 5 year point as preventative maintenance. It was giving no trouble, however. My yard did it over the winter while the boat was out of the water, so unfortunately, I can't tell you how they did it. I am fairly certain it has to be done from the inside and I'm about 99.99999% certain it would have to be done while the boat is out of the water.

I asked the factory before having this seal replaced and they sent me the information below. It's for a GL33. Don't know whether it might be the same for you or not. My GL33 shaft is 40mm.

Factory comment:
Comment from Seaway: Shaft seal you can use any that will fit. Most common can be from Volvo Penta. We use Tormarine products: Stuffy box | Tor Marine
It is 40 mm shaft diameter. So stuffy box adapter is p/n: 1340000 Adapter for stuffy Box | Tor Marine Based on this you can choose suitable seal.

My yard used a 40mm Volvo Penta shaft seal.

The seal is water lubricated. My yard gave me a tip to push on the shaft with my foot after spring launch every year until I see a few drips of water come through the rubber boot. If you don't do this, it's possible an "air pocket" can keep water from coming in and starting the lubrication process. I have followed this advice and have never had any problem.

I have never added a couple of drops of grease to anything in this region. Never knew I was supposed to. What you describe just sounds like they're trying to be over-protective of the rubber boot so there's no risk of it getting chewed up. So, I guess a drop of grease there certainly wouldn't hurt.

I have never had any problems with the vibration-damping components. I have never lubricated anything in this area, either.

As far as the shaft seal is concerned, if it's not dripping water into the bilge and you have no unusual vibration, I would absolutely not worry about it for your upcoming 800nm trip. Plan to replace at home, however, when the boat comes out of the water for bottom maintenance and/or storage.

Good luck and have a nice voyage!

Hi again, PeterB40,
In case it might be of use to you, I checked my invoice from when my shaft seal was last replaced and found that they used the following part:
Volvo Penta 828537

It seems to be widely available. I've pasted a couple of links below, which happen to be European, but they have diagrams/contents.

Sorry - the last two links are in Swedish, but I enclosed them mainly for the pictures. You can use Google Translate, if necessary:

Thanks Scott. Sorry not to get back to you earlier, but have already sourced my 40mm shaft seal w/ 60mm stern tube collar at General Prop. Co. in Florida. Below a link to installation and maintenance instructions. The 3rd pg. is the text in English, and the last two pgs. are the graphics referenced in the text:

VP Fett 828250 and dental irrigation syringe

Our Greenline 39 Hybrid has a 40mm shaft. I was able to 'burp' the air out of the shaft seal and grease it using Volvo Penta Propeller Shaft Seal Grease 828250 (Fett) and a plastic 12cc dental irrigation syringe with curved tip (available on-line). By squeezing the seal with my fingers, I was able to create a small gap at the top of the shaft which allowed air and a few drops of water to escape. I used this gap to insert the tip of irrigation syringe (which I had previously filled with ~2cc of the grease) and applied probably 0.5cc of the 828250 shaft seal grease. I repeated this process on both sides and on the bottom. Since the syringe has a curved tip, I was able to insert grease on all sides. I didn't estimate how far I inserted the tip of the syringe, but since the gap was allowing a few drops of water to escape, I figured I was lubricating the wetted surfaces and getting more grease in where it was needed rather than just by rubbing some on at the seal/shaft joint. It was easy to fill the syringe by removing the plunger, squeezing some grease directly into the barrel, then replacing the plunger.
