Hats off people. 18 hours solid graft to replace 1 turbo. Ok it was the stbd turbo, but still. I have more bruises and scrapes than the day Paarl High absolutely murdered us on the rugby field.
Can you guys just answer one question. When access is that tight would you have lifted the engine out or also dismantled it?
 
It’s very difficult to find the double jointed midgets with seven foot arms required to work on some installations
before I retired I recall some of the larger mainly commercial firms the insisted on have two persons on any job and I certainly remember wondering when I would be found as I was convinced that I would not get out of some of the spaces I was working on
I think that some customers were less than appreciative of the time sheets for dismantling and rebuilding of their boats

Maybe a good idea to put boots over battery terminals.
Recent thinking is to box batteries and vent overboard for gas

The batteries have their own dedicated blower. Boots I agee against short but no boots for those batteries, I tried for a survey and same for fully enclosed box. Thats what happens when you buy off piste leisure batteries that sing and dance but not particularly popular on the cheap.

Anyway. Howcome no comment on my servo pump oil leak. Its spattered all down the bilge. How infuriating to find that on first start up after 18 hours grind! Its like the boat bloody hates me this month!

Oil splatter might help combat all that rust ???

Its an engine. Oily bits inside. She needs another coat of paint. Lying idle from 2019 to now has not been kind to her and having a wet bilge by design really doesnt help.
 
Our boat has a Yanmar 4JH4-HTE.

This morning I successfully re-attatched one lead, simple lucar type right angle terminal, to the Tacho sensor.

Because of VERY restricted access, not the install, but the engine designer, it took 1.5 hours.

The sensor did not help, twin vertical terminals with an insulating vertical section between the two terminals.

Without the central insulating piece I could have done it by feel.

How or why it became detatched I know not, but suspect that the terminal had been fitted poorly, the male inside the insulating cover not the middle of the female.

And have I mentioned the Impeller change........................................ :(

Sometimes Marine Engineers DO really earn their money.

The well respected yard in Gosport who fitted a Stripper rope cutter to a composite P-Bracket by drilling and tapping the GRP and screwing the fixed blade to it.

Stripper sell an accessory for such P-Brackets. The yard did not suggest anything extra was needed and the first time it picked something up, it just ripped out the three M8 cap screws and the fixed blade dropped into the 'oggin.

Do it yourself or find a good one.....................................

18 hours doesn't even go close to the time / effort of lifting an engine. I bet the next time you woould do it in 5 or 6 hours.
 
Id have thought lifting an engine the easier job. But things have changed since I was a teenager and could lift a Ford Cortina engine and drop the gearbox in 40 minutes. We used to think the Alpha Sud was hard because you dropped the engine and lifted the body.
Im sure with the right equipment it wouldnt take more than 3 hours to lift mine once the outdrive was off.

As for 5 hours. This is the first time I've removed the stbd one but the port one Ive done a few times for access to the shield. But that was done over the length of winter with many jobs between, and easier to get to.
