[C320-list] Slow Starting Perkins M30

[Scott Thompson]

And lots of black smoke would suggest the engine is getting too much fuel, not too little.

> I suggest you test to see if its the glow plugs, I had the same issue. Use a heat gun to blow hot air into the air intake of the engine for about 15 seconds. Try to start the engine right away (without priming the glow plugs) , if it starts right away you can conclude the glow plug is the issue, if not, you can rule it out.

I have changed the fuel filters several times over the last 5 plus years with no problems with starting or running the motor after installation of new filters, or at any other time.  I heard about a number of other boats starting hard, quitting after running for a while, the need to bleed air from the lines, etc, but I had not had that experience.

I had to crank it for quite a while, after which it finally sputtered to life, along with a lot of smoke (also not typical).  After it started & ran for a while, it started immediately when coming back to the marina, etc. – so I thought the issue was behind me.  But, the next time I started it (a week or so later), the same thing occurred. So, I anticipate that it will act the same way the next time I start it.
