[@multa765]

And now a hoist out to replace that cheap seacock. Thanks for the clear video.

If the impeller shaft leaks due to salt crystals scouring, it drips on the long under pipe causing failure within a year. You can re-use the scoured shaft if you turn the impeller oil seal around. I spray grease over all the 3 oil feeder pipes twice a year. I've motored all over europe and put 5000 salty hours on mine, 4 impellers, one long lower return pipe, 3 internal anodes, one impellor oil seal and very little MGO 😉 Good video P.S I once had the engine diesel filter come loose and had to turn it and bleed her. I gave her a hosepipe flush once. I have a stuart turner sea-cock and raw water filter and replaced that short pipe twice 🤣 I changed to stainless bolts for ease of access on the impellor and white silicone sealant years ago, 5 minute change on a lee-shore 😉 Due to no money my engine has been held in place after all 4 engine mounting rubbers came away by about 40 very big cable-ties, not too tight, not a great option but, it will get you home...

Hi Sailing Seamurai Thanks for this great video. Since I changed my impeller, the cover from the impeller is leaking water. Had you or anyone else this problem? How can I seal it up again?

Helpful video. Well done ! A reminder to me to do the same! Now to find that damn seacock! lol

Protect the pipes underneath with cosmoline spray like CRC 06026 Heavy Duty Corrosion Inhibitor and better yet some Densyl Tape - DENSO All Purpose Petrolatum Tape. Your oil line is rusting already!

[@sailingseamurai]

Thanks for a good tip! I noticed it couple of months ago as it got worse so will definitely do that!

Do you still have your boat? I lived in Japan for six years and have a dream of sailing the Inland Sea. Would appreciate a chance to ask questions.

[@sailingseamurai]

Hi, yes I still have it. Inland sea is beautiful location for sailing indeed. Many scenic areas and places to stop and experience Old Japan.

You didn't turn the seacock back on? Or if you did you didn't tell others that don't know boats to make sure to turn back on so they don't burn up new impeller other than that great video

[@sailingseamurai]

Hi, thanks for comment! Yes seacock needs to be turned back on. Disassembly and assembly steps are assumed to be mirrored around the subject of repair.

Why the annoying music? You speak at a low volume and the jazz is at a higher volume. No happy medium so I moved on.
