Starting a Lister JP2

Watch in HD: http://vimeo.com/3134959
Starting a 1953 Lister JP2 in royalty class motor boat Victoria. The sequence goes like this:

- Check the oil (it's a bit low at the moment!)
- Grease the water pump
- Set the throttle (it's actually overriding the governor)
- Move the valve lifters to open
- Put on the "Patented one man auto start string"
- Place the starting handle
- Make sure your thumbs aren't crossed over the bar (in case of back fire)
- Turn like hell (especially if it's cold)
- Once firing on one cylinder drop the valve lifter on the other cylinder
- Once running up to speed take the throttle over ride off, ensuring that the alternator is charging (light goes off).

The next bit, not normally done unless running under high load (like pulling a loaded butty, or high speed river running), but for the video:

- With enough throttle turn the change-over valves quickly and smartly to the "run" position. This puts a second chamber in communication with the main chamber thus lowering the compression ratio. This reduces stress on the engine, but needs extra heat in the engine to run cleanly. Note that during the change over the cylinder vents outside (hence the need for some throttle).

Note: The engine was hot during this start - in fact I started the engine over 10 times - hence the heavy breathing at times :-)

great video ,at 1.17 on the video ,wheres the water coming from

[mykaskin]

Thats the cooling water, pumped through by the reciprical pump on the other side of the engine. The tap (shown in the video) allows manual control over the amount that goes through the engine, thus allow you to keep it at the correct temperature for running (if you know what you are doing!).

mykaskin- yeah- love your vids went and checked out your new prop on vimeo...thats amazing it has no trouble turning that 28 inch prop! Tell me- i have a lead on a petter/mclaren with a parsow trans. i believe 20 hp marine built around the 1930's- runs...would that have similar torque?..

[mykaskin]

I'd need to know more about the engine, best measure is swept volume and max RPM and reduction box ratio. The JP2 is just under 3 litres, and 1200 RPM. The gearbox is a 2:1 giving a shaft RPM of 600. The list is 22 BHP, but is obviously equivelent to a much more powerful modern engine.

[porpoisefathom]

whats the hp for this?

[mykaskin]

@porpoisefathom It's 22 bhp at 1200 rpm, but theres loads of torque!

very very nice :)

@rightfredsdead it is 2 cylinder, lister is the make

[foreverthewho]

@Amazon5923 yeah, you're right,, happy with the CE too.

[Amazon5923]

@foreverthewho

why the regret engine power about the same--l have 3!

[PistolPete2]

What a sweet running engine!

[bultskalle1]

nice video production even filmed when the green charging light goes out!

[foreverthewho]

this is really nice! ive got an lister 2cylinder CE 18 hp in my boat but some times i regret that i didnt put one of these in my boat

[rightfredsdead]

@gengnepal these are a 6 cylinder engine. thats why they are called 'lister' engines. that is the latin word for the number 6.

[gengnepal]

how many cylinder?
