Mine does exactly the same thing. If you drop a skier, turn off for 5-15 minutes, it fires right back up. Let it sit for 25 minutes to an hour and it has to crank for a bit, not 5-10 seconds, I'd say more like 3-5 seconds. It's done it for all the time I've owned it, and since it runs perfectly otherwise I haven't tried to fix it.

Since you have changed all that it might be worth your time to work on the LP pump as well first. Might want to get your hands on a fuel pressure gauge as well. Just curious you have changed the rotor,cap and button. Whats a button?

Sounds like one or more leaky injectors or a leaky fuel pressure regulator putting some extra fuel into the engine while it's off. Probably fires right up when the engine is cold and if you're using the boat and you turn it off for a short time it fires right back up cause it hasn't leaked enough in to flood the engine yet. Let it sit for a longer time like 63 skier said and it's getting flooded and that gives the long crank time. The amount of leakage affects the times obviously ![]() |

I’ll agree with Keno. But do Check timing first. Seems like this becomes a common issue on GT40’s |

lol, my dad always called it Rotor cap and Rotor button. I bought them but didnt change them out because the current cap and button looked new. |

Yes Dave same pump on all of them,it either supplies the HP pump direct on a '95 or supplies the FCC on the others . Found that just surfing one time . Wonder how many have been replaced that could have been saved

You know I thought about replacing the injectors because of their age. From the little research I did, they weren't that expensive. I could be wrong tho. |

A simple fuel pressure gauge will tell you if they're leaking.

just looked at the injector prices again. I retract that last statement about them lol. thanks, ill look into a manual gauge to check it |

I guess my thought behind ignoring mine is, I don't believe the fuel drip is causing damage. The added pull on the battery plus heating up the starter to do some extra cranking is not a concern for me, does it reduce starter life, maybe, but my feeling is a starter with proper amperage flow to it from a good, fully charged battery isn't experiencing reduced life due to some cranking. And I'd say 90% of my restarts are hot starts, in that reduced down time period, only 10% after sitting for a half hour where I have to crank extra. So maybe a few times a week for 4-5 months?
Then again, 10 seconds of cranking is quite a long time, if it really is that long I'd probably be looking into it more. |

I’d say my longest crank was 5 seconds. It’s just a pain in my behind. I spent a load on it on maintenance in March so I want it to be right. Not to mention everyone in the boat looking at me with big eyes while it’s spinning over. I hate that. I’ve got a fuel pressure checker on the way. I may go ahead and put a new LP fuel pump and fuel pressure regulator on it anyhow. If the pressure is ok and all that’s been done the only thing left will be the injectors leaking.

Gary, Wonder if a regulator from auto zone would be the same thing? It’s $40 vs nautique parts $215. |

I know what you mean by people looking at you when it's cranking, but most of the time I have people in the boat that know it well and aren't surprised. With newbie's I've definitely had a couple of "uh oh's" before it fires up.

Yes the auto regulator is the same off the top of my head. I believe this is it

Awesome thanks so much. I’ll pick one up. Sometimes I think nautiqueparts is crazy high because it’s a nautique and we have our cart full anyhow so we may as well pick all of it up. I support them. Thousands this year but if I can get a cross reference and it’s the same part I am going to do it. Thanks again! |

Is there a reason all these were changed, or was this all done because of the long crank when hot issue? |

I just bought the boat in feb of this year. I wanted to do these items just so I knew that they had been done. I plan on keeping it for a while. It has 605 hours on it and yes maybe some of the items I replaced didn’t need it but I’d rather spend the money on it knowing that it’s Been done. The previous owner is awesome. Still works with my questions when I need him. He did tell me about the long starts when warm. Said it drove him nuts but it never left him stranded so he just let it roll. Well, it bugs me and I’ll find it. I still would like to do a LP fuel pump $80 and a fuel pressure regulator also $80 and maybe a TFI module. As soon as it warms up I’ll do a fuel pressure test and leak down to see where I stand. |

Fuel pressure is the best place to start after you have confirmed spark. One quick simple check is can you hear the fuel pumps prime when you turn the key to on position before you crank the engine. Adding a fuel pressure gauge to GT40 tool kit is the best $45 you will spend
