Starting problem with warm engine

Hello guys!

My name is Tom, I'm from Germany and I have a 5.7 V8 Crusader in my old Boesch 510. Some of you may know that beautiful Swiss boats. For those who don't: Check the link for some impressions of the current models: http://www.boesch-boats.ch/

I now found that great forum and hope that you guys can help me. Unfortunately I do have a problem with the engine. It runs fine and also starts well as long as the engine is cold. However, as soon as you drive around a bit and and the engine gets warm the engine does not start again after shutting it down. By "not starting" I mean that it does not even crank and the starter does not do anything. As soon as you wait like 30 minutes to let the engine cool down again everything is fine.

Does anybody knows what the problem may be?

Best,
Tom

Re the Boesch boat...where's the fridge, the micro wave, the shower, the TV etc...??.:eek:

Seriously, it sounds like an electrical problem and I would start by ensuring all connections at the battery and starter are firmly connected. I had the same problem with one of my engines and found that a battery cable came loose, just a bit but enough to "kill" the engine until the entire motor and the area around it cooled down.

If it is an internal engine/electrical problem I will secede to th electrical wizards on this forum, one of which I am not. :eek:
 
If all the connections are good at the battery and starter motor, the problem may be that the starter/solenoid is not working properly when hot. When the problem occurs, you could try to cool it down quickly with cold water or an ice pack which wouldn't wet everything.
 
I had the same problem in an automotive GM 5.7. Totally dead, no sound, clicks, etc. until it cooled. It was a bad starter solenoid (at least that is what cured it) but I suppose it could have been a bad connection that was fixed in the change out.
 
I had a similar problem, but with a race car. The heat of the headers running past the starter caused the solenoid to hang up when hot. The solution was to simply shield the starter from the heat.

This should NOT happen in a boat, however. A new solenoid should cure that.

Many common items listed above...Also, check the ground on the slave solenoid. May also be a dust build up around the commutator of the starter.

an extra set of hands and a test light should be adequate to find the root cause in well under an hour.
