This large port single use booster rocket when triggered would provide an uncontrolled 20 second turbo boost

You just want an easy way to run from pirates...

so, you strapped this to your ship and forgot to add a release mechanism? cmon, think smarter than this - we aren't kerbals!

Uhm no.

Just pay.

Or a way for rats to chase .....

Gotta luv this last note:
On the bottom of this booster, "CAUTION:CONTAINS BOOM" is written.

I like the overall idea, but not the stats. Twenty seconds is a very long time. I would change the duration to five seconds, up the uses to two or maybe even four, and add a 250 energy cost to fire (or alternately, a five second cooldown timer). Or if you really want it to be a single-use item, give it a five second duration but a 250 m/s top speed, and maybe boost the thrust slightly. That would be enough to give you a roughly 1000-1500 meter lead on whoever was chasing you, depending on how heavy you are. Though that might still be a little OP even for a single-use.

Whatever the case, I think this thing should create a damaging exhaust plume behind your ship. Maybe not a huge or powerful one, but it would be great if it at least felt like a gauss to the face if somebody lights one up while you've got your nose up their tailpipe.

I was trying to keep to the middle road with the stats - I'm sure a mk2 version would likely be requested with different stats eventually. A higher top speed but a shorter burn time would also be a good trade off and it would still help close the distance during a long intercept as well.
