Re: Northern Lights Genny
I used to run a boat with a pair of luggar powered 20KW NLs. They were pretty much self bleeding. It was a few years back but I don’t even recall a priming pump. The lift pump was electric and you d just hold the run button to run the pump for a while to bleed the circuit
Very reliable

Gee, too bad you don't know of a fuel injection shop that could test those injectors for you.
Re: Northern Lights Genny
Don't worry, if I swap them you'll be getting them.
Re: Northern Lights Genny
How old or reliable do you think you spare injectors are? Fresh or recent pops on them?
IMO, Injectors that spend more than a week on a shelf, are suspect.
Nice to have for emergencies when you know you have a bad one on your engine. Your spares give you 3 chances to replace one bad injector.
But when your engine is running fine and then install stored injectors, you may be inserting problems.
While your are looking for DIY adventures, adjust the valves.
Re: Northern Lights Genny
At the risk of jinxing myself I don’t think I ve ever had issues with injectors.
My 20 year old 3000 hours Isuzu powered Norpro 18 has its original injectors. The NL 20s I mentioned had 9000 hours and where 13 years old when the boat sold. Original injectors afaik. I put 4/5k on each and never touch the injectors. We had to replace an injection pump on one of them but GT hat was it.
Same on mains… I ve put like 4000 hours on 3412s, 2500 on C32s. Never had to get an injector replaced.

Yea, that's why I'm concerned. But since the can of worms is already open, welllll ...
Re: Northern Lights Genny
There are many current or former aircraft owners on this board. After upgrading to my best mechanic over 15 years, 2 states away, his opinion was always to avoid maintenance induced failure from a repair, UNLESS the risk of the repair was warranted by great data, or significant calendar risk that warranted the risk(Part 91, obviously). Boat engines are usually less risky to human life. IMHO, the injectors should stay in their boxes, until needed.
Re: Northern Lights Genny
Not being an aircraft owner, I have always thought that the name of the game with aircraft maintenance was to perform it on a schedule, such that things never really break in use?
Whereas, with boats, it seems like no one wants to touch anything until it breaks?

If we test them, you'll know whether you need to swap them or not. No charge for pop-testing. Just saying.
