Yanmar 1gm10 Oil Change

Pela is great.
Before they were common, I took the sump off my 1GM-10 to clean it out, I also drilled and tapped it M6 at the back, i.e. the lowest point. Otherwise you could only drain about half the oil.
I found a plastic cat litter tray fitted nicely between the engine bearers, caught the few drip while running and kept the bilge clean.

I disagree with the advice to use cheap nasty oil, I prefer a semi-synth (at least) for any engine I wish to keep for many years. I suggest doing your own research and deciding for yourself.

If a Pela seems a lot of cash, you could use a big oil syringe as this motor does not hold much.
 
The reason for using a relatively low spec oil is to prevent glazing of the bores and the associated loss of compression and power and increased oil consumption.

Boat engines are lightly stressed, low output units which are generally run at constant and low speeds. An oil designed for a modern, high revving, high output car engine can provide too much lubrication leading to combustion products not being removed by the fractionally greater friction that a lower spec oil allows.

A similar outcome can occur due to running the engine too slowly for long periods. Most marine diesels are happiest being operated not too far below their maximum output revs.
 
Cheers guys. Appreciated.

Finally you see loads of people using the Pela Oil pump. Are they really worth the £30? I've alrways been used to crawling under a car engine and getting the sump valve off so pumping it out seems a bit alien but I'm happy to go with the consensus if someone says it is worth every penny.

Thoughts?

Yes they are, oil and filter change now takes about 15 minutes, also good for hoovering up last drops from bilge.

I bought the big Pela which in retrospect was a bit of overkill for a small boat.

You can get cheaper lookalikes but no idea on quality.
