GT40 takes longer to start when warm

Maybe you missed it earlier, but what's your idle speed in Neutral and in gear? (there's a reason for asking) by memory 650-700 in gear Sounds normal If your ECT sensor. ACT sensor or MAP sensor are reading out of range, a default value gets fed to the computer and the idle is set at 800 rpm by the computer. I think like SNObsessed said, I'd be looking at sensors and the wiring to them and throwing money at sensors next. A sensor can be reading bad and not be out of range. The only way to convince yourself that it is or isn't the LP fuel pump will be to change it

Ive got the TFI sensor in my cart lol

Any others I may need to look at?

It does not bother me one I-ota to throw money at parts that I know can fail to help my peace of mind. I've towed and been towed and neither were fun. This boat is heavier than my last 2 boats combined. I cant imagine having to float it on the trailer while wading in 4 feet of water with a dead engine while the dock is full of people fighting over 2 ramps

ECT is engine coolant temp
MAP is absolute pressure

whats Act?

By the way, you'll find things in the manual that don't pertain to your engine since it's more accurate for the OMC/Volvo versions of these engines and it would seem that PCM just rubber stamped it without a good proofreading

It ain't the best but it's all we got

Another thing you can do while you’re waiting on parts is... in the manual is a section called “Theory of Operation” it explains what all these sensors do and and how the fuel system works to make the GT40 run.
Helps with trouble shooting when you understand how it all ties together.
It starts on 2A-17

dang right i need that thanks!

I don't believe these sensors are marine specific (somebody correct me if I'm wrong) and while I like to support Nautique Parts and SkiDIM, sometimes their engine components are absurdly overpriced (i.e. low pressure pump).

It would be great if somebody has NAPA or similar part #'s for any of these things if they posted. Could save us all a few bucks if we don't have to buy the PCM offering.

you still on that 100x40 lot and burning up? lol

They can't be expected to sell at the same price as a national parts supplier. Kind of like buying everything on Amazon and then wondering why your local store closed.

I don't disagree and don't have a problem paying a fair markup at the "local" retailer to support them. I feel good in knowing I have purchased plenty through those channels. But there is a point at which that's no longer reasonable.

Take the low pressure pump I mentioned. That is sold for $215 at the "local guys." I purchased the exact same pump for $69 elsewhere (and they are still marking it up). That represents an increase of 212%. That is past the point at which I'm willing to be generous with my business. In fact, it feels more like they're trying to stick it to me which I don't appreciate.

But this is what makes our country and capitalism great. If the small guys can get people to pay that then more power to them!

I agree on the service point, obviously if you are not receiving good service then they don't deserve your business. And I grant you on the LP pump, that is just too much of a difference.

I guess I'm just sensitive to this from hearing too many friends rail about the price difference of this or that at a smaller shop, then when they need some special fastener they want the same shop to spend a half hour figuring out the right $17 part and special order it.

I hear you Dave. That's why were are in trouble today. The money we saved by having stuff outsourced is now gone how many times over. Hope this is a wake up moment

Spark plugs are a good example of getting it stuck up your behind

In this case it's PCM doing the gouging, just like most other OEM's of things like tractors, cars, ATV's, snowmobiles ..............and on and on. The dealer could easily sell you the same plug without the packaging for a lot less

If you want genuine OEM supplied parts in genuine OEM packaging, which is all that some people will buy, you're gonna pay for that.

Don’t forget there’s a certain way to check and set the timing.

Update: I did the LP fuel pump and pressure regulator. Still a long hot start. Say 5 seconds. Timing is next. Just and update for others with same issue. I’ll report back after checking base timing.

Well at least now I know where to go for used GT40 parts.
Those relays can be cheaply purchased at the local parts store.
