Intermittent Starting Issue

Hi all,

A newbie to the Team Talk page, but have been on a MC for the better part of my life, I am 23. My father has lost interest in the MC so i have taken on the mechanical issues (he still wants me to pull him around the bay...)

The Issue- Intermittently have an issue getting the starter to engage. I hold the key to the start position and if i hold it long enough it usually starts. Sometimes i turn the key back to off and then go to start, pretty much same results. Because it does not matter what i do with the key, and when the starter does crank it cranks well. To me it seems that would lend itself to a solenoid/relay issue. I also cleaned the main ground cable, and that seemed to change nothing. When the engine is warm it seems like the boat will start much more regularly.

Looking for advice!- Thanks

Welcome to Team Talk. I'm not quite clear on what is happening. When you turn the key to the crank position, does the starter motor turn, but not engage the engine to turn, or does nothing happen?

Sorry about that, when the key is turned to crank, nothing happens. Sometimes it will crank first try, sometimes it will take a few seconds holding the key to crank. No apparent rhyme or reason to it.

Not sure about the setup on your boat, but if you can find the solenoid (some newer ones are part of the starter), you should be able to bypass it and see if the starter engages...

Plenty of videos on youtube, mostly cars but it's the same principle...

When it won't start try wiggling the shifter, could be a neutral safety switch.

if the neutral switch isn't it ... if it doesn't start go back and tap it with a hammer then try again if it goes right away you probably have a dead spot... rebuild or new or carry a hammer

Yep... Sounds far out, but it works on semi trucks...

How much is a rebuilt starter anyways?... Can't be more than a couple of hundred...

Sounds like a starter relay issue. It should be located on the back of the engine above the trans bell housing. You can usually find it by having someone turn the key while you listen for a click. Simple parts store item.
