Tutorial for how to do a regular service of a MaxProp Propeller.
We have owned over 150 boats and helped in boatyards for almost 30 years. In this time we have serviced a few propellers while also teaching others how to do it. There are a few little tricks that make it easier as well.
This video shows the service of a standard MaxProp that is found on boats from 10 feet to over 100 feet. The actions of the service are the same for the three blade prop that we have in the video and the 2 or 4 blade as well. The basic service of the MaxProp is the same for the Classic Model and the newer Easy Model.
This video has the 3 blade easy model of the MaxProp.
We are not sponsored by MaxProp, but I recommend the MaxProp service kit if this is your first time servicing your prop. It is not expensive and is a good thing to have in your kit if you are cruising the world. The regular service work can be done under water in far away places if this is ever needed, or the kit can sit in the garage for your next do it yourself prop service if you cruise or race closer to home. Each of the pieces of this service kit can be replaced separately in a good hardware or automotive supply shop, but it is worth a couple bucks to get the right stuff the first time. The crew at MaxProp will also help you to select the correct zinc and make it a part of the service kit at a small discount. The zincs for the classic and easy models are different. If your prop has the numbered ring that you see near the propeller shaft that this prop has - then you have the easy model. If you do not see this numbered ring - then you have the classic.
There are also "aluminum zincs" available for most MaxProps but in my personal experience, these do not last as long as the regular "zinc - zincs" and I do not recommend them unless you have a special need.
This is the second video for our new Real World Sailboat Repair Channel. We show you how to get this repair done out in the real world just the way that you will have to do it instead of on a bench or shop. Please pardon the less than perfect sound as we are doing this prop service out in a busy boat yard.
We have already shot several other videos on subjects that range from mast tuning to spraying bottom paint on a racing sailboat. Please subscribe and feel free to ask any questions. We are more than willing to help. Your boat should be fun and knowing how to repair it is a major step in keeping it fun.

MaxProp recommends filling the forward hole first. Also, the prop should be spun with each pump of the trigger.

Point well taken. I have not seen a difference but always go with what the factory recommends
Thanks very much for your very helpful video.
Great video! Now you've got me worried that one tube of grease won't be enough. The kit only comes with one tube, which I would assume should be plenty for a prop that hasn't been neglected?
Anyone know if this can be done while in a slip???? Or is a haul out absolutely required? I'm a little worried my prop lost all its grease

It can be done in the slip.
you needed to remove the front set screw and grease that location as well. That forward setscrew is longer and acts to also prevent the pitch ring from moving forward. If you put too much grease into the forward end (two front locations) it can actually bind up the prop rotating....just remove set screws and let the pressure release and reinstall. Keep in mind you need to rotate the prop full end to end every few pumps of the grease gun to disperse the grease inside the propeller.
I didn't mind your video or narrative,m at all, but I believe you missed a key step which is to pump then remove the pump and rotate the prop back and forth to release air, then re-pump and repeat.
Great video, thanks,. My MaxPro is older early 80s, and does not have grease holes. This prop apparently must be taken apart to grease. My friend and I are going to tap holes and install the screws.It will make maintenance much easier He has matched the thread and done a few practice holes on structural bolts to make sure. What we are looking for is we know the grease hole are 180 degrees from the 4 screws holding it together. Any tips on measuring for them? We are going to try and do this while its on the boat. The allen screws holding it together look a little suspect and its too close to spash time to start pulling our stripped ones. The prop is on an 83 Irwin Citation and is 63 MM. thanks, Ill try to post some photos or video of this back to you

Smart move. Remember to drill slow and not push too hard to keep as much of the shavings as possible from being pushed inside the prop. With a little grease instead of drilling oil you should even end up with all of it outside at the end.

@@sailboatcareandrepair I took photos and we did a drawing of what we believe would be the inside, based on videos and manufacturers material. We tapped and and greased it, seems to be working fine and grease came out where it was supposed to. I will send the materials along plus some pointers. Not to hard to do
