Hand crank Hydraulic start for small diesel

In my time upon ships the small diesels on the lifeboats always had a hand pressurized hydraulic start. Do any of you run these? One of the boats I’ve owned had an easily hand crank able single cylinder diesel, but something with multiple cylinders is tougher to manually crank. The hydraulic starts in referencing are simple, bullet proof, and you can just crank it back up if you blow it.

There are some smaller 2-3 cylinder diesel that can be hand cranked. Search “hand crank marine diesel” on YouTube for some examples.

Try looking at "Lucas Spring starters"

My old Volvo 2003T (3 cylinder) came with a hand crank. Release the compression lever, spin the engine then pop the compression release. Should work with most small diesels having a compression release.

No, I don't, but a couple of guys I knew had engines you could hand crank.
Both were single cylinder, one a BMW, the other a Sabb.
Perkins had hydraulic starters available, so did GM.
As a side note, were you the one who posted an almost identically worded post on another boat forum just yesterday?
No big deal, several here are on other forums, (me too).

Cranked a Yanmar 2gm once. Throw the compression relief leavers and get up to speed, then pop it.
