Can you give me a name of a supplier I am planning a second long distance cruiser with a two to three litre engine. and would like to make it able to start after partial flooding. Michael Pope
That is a ďrealĒ air starter, like the big boy motors that actually actuate the engine directly.
That would be a real significant modification, be interesting to implement it as you could leave the standard starter alone. Iím sure you would have to remove the head
and have a HP air port drilled in it, and then figure out some kind of timing system to give the shot of air at the right time, run it off a a SCUBA
tank Iíd assume.
Itís I believe an interesting concept
, but way more work
than itís worth.
I believe they are talking about units to replace the existing electric
There are or have been wind
up spring starters too. Hydraulic and or air starter would in my opinion be a lot more work and money than you need.
Carrying a spare electric
starter would I think make more sense.
The APU on the Apache helicopter was hydraulically started. It was started from the emergency
hydraulic accumulator, you had one shot, if it didnít start, you had to pump on a one meter long handle until the accumulator was 3000 PSI again and you were about worn out.
Of course you have to have an accumulator, a nitrogen tank that acts like a spring for the accumulator, and a hydraulic pump to recharge the accumulator, and a manual back up pump in case the engine didnít start.
Real complex system.
I believe there are emergency wind
up starters in existence, never seen one though.
I just carry a spare Chinese starter, maybe $100 or so?
