Removing the sail drive from our cruising catamaran

- Our 2 Volvo Penta sail drives are in desperate need of a service. We need to replace the seals in order to ensure our 30 year old Catana catamaran remains water tight! In this episode Harry and Shayne share how they remove the sail drive from the starboard hull and get it ready for a clean, service and paint.
Work is continuing in other areas too as we get to see the final rudder installed. It's looking sweet and we cannot wait to get Paikea wet again and take them for a test sail.
Plus lots of sanding and painting going on as we get closer to top coats on the boot top and new transom steps.

Thanks for the video! I’m curious as to what condition your sail drive rubber gasket was in once you’re removed it? I don’t think my gasket has ever been replaced, but I’ve seen some removed after 20 years and they still looked good, so wondering how yours looked. Best of luck with everything!
Hey thanks! We just uploaded the next video where we show the rubber gasket removed from the sail drive. It was well and truly ready for replacement. The salt water seemed to harden the rubber and we had sea life growing on it. Glad we replaced it as the cracking was enough for us to be concerned.
His a pretty handy chap 👌
He is indeed!
There are a few boat builders who swear that shaft drives are better that sail drives for safety reasons, but almost none use them. Is there really good reason to have a shaft drive over a sail drive?
Yep, there are some that swear shaft is better than sail drive and they have their reasons. Usually service ability is the main reason.
The reason most manufacturers use sail drives is ease and cost of installation.
The argument of the shaft vs saildrive for service costs is becoming a hard one to argue over other factors now. Saildrives have become incredibly reliable.
at 12:45 , how did u get the old 2 seals out ? thanks. I'm thinking to freeze the bearing race with some dry ice blocks, drop the race out. then use a cylinder aluminum to push out the 2 seals . may need to heat the housing too to let the race out
The bearing cup can be knocked out with a punch. It is light tapping all the way around as it comes out, trying to keep it coming out as square as possible.
Once the bearing cup is out the seals are easy to knock out. Putting the new seals in I try to use a big socket the same diameter as the seal.
Hope this helps👍
