Changing the oil in a saildrive while the boat is in the water (afloat) - Boat Projects

In this video, we change the oil in our S130 Saildrive while the boat is still in the water. We have changed the oil in the drive before while the boat was on the hard, but this time take the opportunity to change the oil while the boat is afloat.
Note you can't extract all the oil this way and you need to check the diameter of the extraction tube if your saildrive against the tube on the extraction point to make sure you get a good seal. I still recommend lifting the boat as the anodes will only last about a year but it's useful if you need to change the oil in the leg.

Thanks

looks like the fuel hose is pushing into 20 years old. A future topic?
Also, I did my SD 130S oil change today. I had 2 x o rings on that stopper. I could get 1 liter or so from the dipstick hole, as a test, then got another liter or more from the tube. But, I pushed on a larger tube over the existing one...

Hello, yes the fuel system is on my winter projects list. Keeping an eye on the pipe work for now. Yeah I need to get something to make a better connection to the pipe if I do the oil change in this way again. That’s a good idea going over the existing pipe - good tip, thanks ⛵️

Note you’re only changing about 70% of the oil. The rest remains in the lower casting of the sail drive. If you have water contamination the oil will separate from the water if left un-used. The oil will then float on the water which remains in the lower leg. Sail safe. Ant.

I agree with the quantity of oil you can extract and it’s always best to lift but I do think it’s worth changing the oil rather than just leaving it. In my experience on the last boat which had water ingress in an older leg the water and oil didn’t not remain separate and the oil instantly turned milky.

Hiya
Fascinating stuff but I was wondering if you could answer a question about raymarine radar's compatibility with opencpn and raspberry pi?
Is it true that the RD218 is able to work with raspberry pi?
Sorry but I am new to all of this..
I love your work as you do everything the right way.
All the best

Hi, many thanks for your comments. That’s a maybe, it depends on what the display or mfd unit is. You need to find out if you have a Seatalk HS connection on the back of the display as this is basically Ethernet so can be plugged straight into the PI Ethernet port and then it should work. If you have a E series display you should be good to go. Just to confirm the radar does plug into the back of this display.

@@BoatingwiththeBaileys Thanks for your help and answering my question but what I really wanted to know is which of the raymarine raydomes is compatible with opencpn.
Is it possible to plug in a raymarine dome into a raspberry pi leaving out the MFD?
Many thanks

Hi, not if you have an RD218. It has to connect via the MFD. Here is a full list github.com/opencpn-radar-pi/radar_pi/wiki/Raymarine-radome-model-support
