How long should delay be in seeing water from tell take?

[TownsendsFJR1300]

I guess like he said just some 4 strokes

does not make sense to me either why cold it has this problem.
making sure the pump is in good condition is still something I would do

Exactly, that's why I don't buy it.. Doesn't address it..

Think about it.. Is the WP, water jackets, volume GENERALLY, any different between a two and four stroke?? Noooooo...

Thx again guys.

Was reading a little more on the issue that I am having and had a couple follow up questions. I understand that you can't diagnose for sure over the forum, but wanted to see if you fealt the same about after further info.

In my search about the pressure control valve I have seen a lot of people comment that they have no tell tale at idle or that they overheat at idle. I have neither of these problems after initial start up. Once the engine is warm it runs water fine at idle the rest of the day, even after killing and restarting engine. It also has not overheated at all. Do you still believe the pcv is the most likely culprit? You all know a million times more than me so not questioning your advice, just want to be sure you have all the facts before I go tearing things apart.

Are you saying that if you stop the motor, let it sit for may 5 to 10 minutes, that when it is then started up it pees immediately? Or does it take as long to pee as when it is first started for the day?

[Nnelzon23]

Seems to start showing water immediately after it has been ran once for the day. Even have trimmed it up and ran *****ing motor for a couple of hours, put it back down and it ran immediately. Kinda makes the "time to fill" thing puzzling as I think it would drain a lot back out after it is turned off, unless the trim up is holding water in or the pressure in the lake is not letting it fully drain.

If the motor pees quickly when hot and not when cold, after the motor has not been used for a period of time, and assuming the motor has been left in the same postion (not tilted up) then I am also at a loss as to why the pee difference.

The original question (post 1) simply was about it taking time to pee. Not abnormal is some Yam four strokes. It can be a long way from the block to the tell tale port. Water has to first fill up the block and then make its way through tubing and maybe a rectifier/regulator and/or a fuel cooler before it gets to the tell tale port.

Two stroke design can be quite different. Start some two strokes and bam there is the water. Pissing like the race horse. Start some four strokes and wait and wait and wait. Then it pisses like the old man.

If the motor starts pissing after several minutes, if the motor does not over temp while idling or at power, I am failing to see the problem. Or is this a search for a problem that does not exist?

I have thought that maybe the lake I'm running in could be part of it. The lake is very shallow and very green. Not visible vegetation but probably a lot of sediment. My thought was that maybe that stuff is getting dried in the nipple or elsewhere and causing it to take a bit to penetrate. I flushed after last outing and will see if that changes anything next time out. It is a popular lake and I know a few boaters on it. They haven't had any issues, but none of them run yamahas either.

And by shallow I'm not saying I am sucking off the bottom. Just that it gets churned up by pleasure boaters.

Very well could be a problem that doesn't exist. In fact I hope that's the case. I'm new to the motor, and where better to ask then in an area with a lot of experience. I have already learned a lot from you guys and appreciate every bit of it.

[99yam40]

we can not give up on what could cause this lag when cold.
things like this have to be solved

[TownsendsFJR1300]

The bigger engines, filling up, yes, I agree, it'd take longer to fill the powerhead.

My F150 is larger (not sure how much more coolant) than his 115, and pee's immediately,

But the temp difference does not make sense..

As 99Yam posted earlier, with the engine new to you, I'd R&R the WP. Just
as you don't know its age.

Perhaps cold, the impeller has a good "set to it" and doesn't flow as well till its warmed up some, dunno, (but it is basic maintenance in any event.).

[Nnelzon23]

I will let you know how the next run goes. Maybe tomorrow if the weather warms up a bit. 100 degrees through June this yr in Iowa and now low 60s in July?

Wish it halfways to 60's here, still low 80's @ 9PM...

Good luck on your run..

Got a chance to get back out tonight. If you remember, after my last outing I flushed the motor, but then let it drain and set for roughly a week. This time out, the motor started running water immediately upon firing the engine. All I can think is that there is some crud left in the motor from the water condition of the lake, and that is what was causing the delay. Thx again for all thoughts and information. I will keep an eye on it and keep posted.

That "crud" may take sometime to dissolve, but also an obstruction can act as a valve holding the water in, somewhat explaining your symptom of immediate water after engine hot (because it was run shortly before, the water retained).

Love Boscoe's descriptions.

Thanks for the update, glad its working as it should...
