Can't start Evinrude Direct Injection 90 HP

[Ribtecer]

Hi Guys

A friend of mine can’t start his evinrude direct injection 90 HP, its as if the battery is flat, it turns over very slowly but won't start.

We tried a power pack and then replaced the battery with a brand new one - still the same.

The power lift works just fine and all the other electrics are working perfectly.

Any thoughts?

Thanks

Toby

Is it a new engine or has he had it running before?

[Ribtecer]

He had it running on thursday evening - no problem - over to Cowes and back to Southampton, then today we went to use it and it wouldn't start???

Check the battery conections on engine/battery/switch for tightness or corrosion

As Peter says check all the connections. How old are the battery cables? If they're old they may be damaged inside. Try hooking your jump pack straight up to the engine and see if that makes a difference.

Check that the kill chord is in place. I been called to many "cant start my boat " calls only to find that they forgot the kill chord.

More details of whats hapening..... is it turning over etc....

My tohatsu has a start problem at the moment. It struggles to turn over as if the battery is flat. The problem was solved before by dismantling the starter motor and carefully cleaning the commutator with fine emery cloth. The problem however reared its ugly head again off sconce in the solent and so I had to get a tow back into yarmouth

I have come to the conclusion that the starter motor is knackered as it cannot produce enough power to turn over under load. The brushes may just need changing but not too sure.

I posted on this a few threads ago .. most people can repair their own starter motor .. getting the bits is the hard part

Try a different battery - sometimes you can have a few cells down - will cope with medium loads but not heavy ones - internal resistance means the booster pack will not help at all.
