Starting Proceedure

Brian - The experience you have given your boys, working on a machine, is worth many times the parts cost you have laid out. I'm sure they have picked up tips they will use the rest of their lives.

Good luck on the carb!

Still here at home. Going to wait for rebuilt carb to be repaired.

Not griping, but you all might have the bucks to sink into a boat like you talk about, but I don't. So we have been working on this a bit at a time with my boys. It's been a fun project. (Yes new plugs). You all have been at this for a long time, I am just trying to get a boat going to share with my boys now that they are grown up so I can pass on some fun. We're learning a bunch as we go, but I didn't realize things like replacing the impeller at first. Not like there is a list here online to follow if you are going to restore a boat. (although plenty of good information, we are trainable!) I might very well have to get a new Holley, and pay ON to put her in, but have been trying to do this a step at a time from the start. I thought we we pretty good redoing the entire fuel system, then reworking the Plug wires, Plugs, Cap and Rotor and battery. That was a good place to start. We've also put new Valve Cover gaskets and manifold gaskets on and a thermostat. (should have seen the old thermostat!). We've done a little rewiring.

We'll wait and see if the rebuilt helps. If not, I'll see about that new Holley.

Really appreciate the comments!!

Well... In a nutshell:

At the mechanic is where it has been seen. Dumping fuel while the mechanic is working on it.

First time we (at home) had cleaned the fuel tank, replaced the fuel lines, installed a fuel/water sep, installed a new PCM fuel pump, and this rebuilt carb. Took it to a local boat guy and said, can you get her started (it hadn't been turned over in 10yrs). He got it started and supposedly tuned it. Called me while he had it to say it started but one of the jets was dumping gas. He wanted it another day to investigate. Said it stopped, and was OK.

Took her to the lake... . After almost running the battery down and a bunch of almost starts she fired up. Didn't want to idle, but she ran. Sounded good for about five minutes. Knonked out. Wouldn't restart.

Took her to Nautiques of Orlando and they got her started on their fuel and told me wasn't pulling any water. Bad fuel and impeller.

Took her home and installed a new impeller and thermostat.

Took her to lake .... She started after a whole bunch of coaxing. Sounded good, but would not idle.

Back to Orlando Nautiques, tries to start but immediately saw it is dumping gas from the front two jets. Recommended I get a new carb and not a rebuilt.

A local had said to take the fuel line off the fuel pump on the tank side and blow through to see if there was an obstruction. We did, there was. I was hopeful his was it. Took the tank out again, cleaned it again, changed the separator and put 90 octane non ethanol gas in.

Back to the lake... Nothing.

Pulling the carb and sending back to National to repair under warranty.

This is where I am at.

haha.. nice analogy

you want to give her a little drink to get her happy but NOT TO MUCH or she will not be able to perform!

On the 83 MC, I pull pin give one full pump backwards then return to N and turn key.. starts right up 98% of the time. If not, (just like with wife) I must have done something wrong I didn't even realize..

good luck with boat and life..

Wait....what....second mechanic??? Man, you really need to find a mechanic willing to get his hands dirty or just start working on this yourself.

What you describe is a fairly common occurrence that we've documented here before. It can have a few different causes.

when is it dumpimg the gas?
A) When it's backed down the launch ready to start
B) While it's running
C) After it's been running and then shut down

A misadjusted float level, a dirty or poor quality needle/seat, a contaminated float bowl or a fuel pump putting out too much pressure are the most common issues.

Did you replace the fuel pump at all?

Let us know when it's dumping.

Dad's 64 Ski Nautique with the REALLY old Morse has the detent...

Well... Actually seemed to like if I pulled back all the way to start. Anyone have an old manual that shows how? Just like to start out with what is supposed to work. Once it was warmed up it started in the center position just fine. Wondered if a certain position puts it in "Choke" Position for cold start or something. Looked at the online manuals but didn't see a procedure.

Just like your wife and my wife, they all work the same only different. Sometimes it fires right up and other times you can try every trick in the book and the bitch still wont start.
