Regal Rush Jet Boat

So, the beep went away. Pretty sure it just needed water to be happy.

I put a brand new battery in it, replaced the starter, replaced the 4ga wire from the solenoid to the starter, took it to the water and spun it till the battery died. Still can't get it to fire. Starter fluid doesn't help so I'm assuming it's not firing for whatever reason.

When I start assuming is when I need to get back out and climb back in it.

Running total: $904.49 Ugh!
 
If you run starting fluid through it your bill is going to get much, much, much higher. That shit will damage two strokes very quickly. It washes the oil off the cylinder walls.

That alarm could be low/no oil alarm or a couple of other things.

Is it getting fuel? Could be the water separator full and shutting off the fuel.

That should have a coil for each cylinder, I wouldn't think all would fail at once.

Pull a plug and see if it's getting spark. Make sure you ground the plug to the motor.
 
Plugs are sparking strong. All 4 of them.

I pulled the fuel line off of the top carb and spun the engine over. It's pumping fuel.

I pulled the bowls off of both carbs and made sure they had fresh gas. All fresh.


Now, if I leave the boat alone over night or an extended part of the day I can walk out there and turn the key and it will fire right up, idle low for about 15 seconds then die. After that it won't hit at all.

I pulled the air cleaner off the face of the carbs and it seemed to have about half a cup of gas puddled there...

Using a spray bottle I spray gas directly into the carbs and it still doesn't start.

This thing is driving me insane!
 
I'm not the best at making these run but did you say the alarm is still beeping? Some of those motors will not run if they don't think there is oil. I would assume that's controlled with the spark though.

Have you checked the compression? Has it backfired while you were working on it? Those have reeds like motorcycle 2 strokes. If they get damaged the fuel won suck into the motor.

Fuel sitting in the intake makes me think something like that could be going on but I'm not sure that would be the problem since it will fire cold. They usually are either good or bad, not really anything in between.

Are you sure it isn't flooding itself on a hot start. Ethanol fuel causes all sorts of problems with these motors. I wonder if the choke circuit is stuck on.

Not real sure what to tell you.
 
If the carb floats were full of gas and sinking(flooding), would it not produce those conditions? After sitting, the fuel clears out and upon starting the fuel fills the bowls back up until it floods again. :dunno:

I've been following this thread and am dying to see you get it.

The long Beep went away after I got it to idle for 15 seconds the first time. I assume it just needed to get the oil primed up.

It ran fine when I parked it except for the noise, which have chalked up to the old starter hanging up. It has not backfired at all. I have not checked compression. That's next on my list. If compression was so far off that it wouldn't run would it start on a cold start?

I had eliminated any sort of flooding since after spinning the engine over, choked at WOT for more than 30 minutes I can pull the plugs and hardly smell fuel. Not to mention they look bone dry.

I'm not getting fuel to the cylinders for what ever reason...

Reeds... I know nothing about them. I need to do some research on reeds. Could they have gone bad from sitting? Where exactly do reeds live on one of these engines?

I'm tired of standing on my head in this engine bay! I ready to be on the water!

The bowls were full of fresh gas but as soon as I removed the bowls I stood on my head to see if they floats were retaining fuel. They were completely empty and moving free. I was thinking something along the same thing as you as well.

See, this is why I love NAXJA. I have a thread on something completely irrelevant to a Jeep Cherokee and I still have people helping me. Best 35 bucks I've ever spent.
 
The more I think about it the choke could be stuck on... the flaps are rather close to closed. Ill hold em open and try again tomorrow... sucks that im at work and can't do it now.
 
Have you actually cleaned the jets in the carbs? There are some VERY tiny passages in there that will clog after 6 months of sitting, much less two years. Doesnt matter if the bowls have fresh fuel, if the passages and orifices arent open, it wont do much...

Check the reeds as mentioned also. They should be shut, but not stuck, and no cracks etc.
 
The reeds work basically as a check valve. Like valves in an engine but they aren't mechanical. They come in all sorts configurations, I don't know which one you have. Here is an example. They fit between the carbs and the motor. When the motor pulls vacuum the air/fuel mixture goes through the reeds and when the piston comes up it can't push back towards the carb. If they reeds are broke they can allow the the mixture to be pushed the wrong direction. They would have to be pretty bad to cause it not to run. In motorcycles the carbon fiber reeds chip and crack which causes them to loose power and have a slow throttle response. A lot of boat motors are metal. They could even be sticking closed.

Couple of thoughts. If you know the carbs are dry do you have a priming bulb? If not put one inline and see if you can prime it again and get it to fire.

I don't know what kind of pickup those have but my current outboard has a pump. It does require priming to fill the bowels and the pump keeps them full.

I keep forgetting it has been sitting for 2 years. I would pull the carbs and clean them out the best you can. You could have a needle valve stuck as well. After it sits for a while the needle will drop allowing it to fill but when the float comes up it sticks shut again. Chances are it had ethanol fuel in it which is much worse for going bad and plugging stuff.
 
Carbs are coming off tomorrow if I have time. Ill inspect the reeds while they're off.

I've been neglecting my grass in order to work on this boat.. I can't put it off anymore... I almost can't see the boat anymore. :)
 
Also, idk if I've mentioned this or not but since I've been messing with it it seems like it'll try to fire on maybe 1 cylinder every couple cycles but no more than that... other than the rouugh idle on a cold start.
 
I think I would check for gummed up carbs first. That varnish can be hell to clean out as well.
 
Well, after cleaning the carbs and still no results I broke down and did something I've never done before... I called up a local boat mechanic and made an appointment. I just don't have time to fool with it anymore. Hopefully he can figure it out!
 
3 months later...

I finally got tired of waiting on him to work on it. I've called multiple times and he says he needs me to help him work on it.

Yeah right, I'm paying him to work on it...

Anyways, I went over to pick it up today. Got it home and immediately started working on it.

Apparently I had overlooked the hose that goes from the air cleaner to the carb. It's a very small hose that seemed to be plugged up pretty good.

Replaced it, fired it up, hooked up to the Jeep and went to the lake.

The product of that yielded this. :)
