Yanmar 2GM question

[edbulmer]

My engine runs great lots of power but it is hard to start. Have replaced both filters and tightened all lines and banjo fittings. Does anyone have an idea of what could be the problem?

Batteries, starter, bad wiring or loose connections? What about it is hard to start. Does is turn over and then die? Or have trouble turning over at all?

It turns over fine but just takes a long time to start.

Air leak. Maybe your bleed screws are loose. With my 2gm I have old loose wire connections. It takes a few pushes of the start button to turn over. When it gets too bad I just squirt some contact cleaner on the wire harness plug fitting. It lasts for a while and then I have to repeat... One day I will just change out the wire harness. One of the many ongoing projects

No loose bleed screws. I tightened them all. I did an engine flush and oil change and gave it a good run. It seems to be starting much better. Thanks for your help.
