Don't know where to start. So many problems with 95 Crownline

[Toyelectroman]

not to hijack the thread but how do you know it's a weber 4 barrel carb? Reason I ask is I can't for sure say what kind of carb I have. My engine is a 5.7lx 1996. Each time I try to look up what it came from the factory it gives me a few choices. It probably does not help that I know very little when it comes to carbs

Visual confirmation. OP posted a photo. I know those carbs in my sleep.

Start your own thread, post your engine serial number and a photo of the carb, we'll have a look at it for you... But that engine, that year, likely is a Weber 9781.

I can't get the serial number now because I have no way to reach the engine until I replace that section of the floor. I don't trust the structural integrity of the rear floor board to hold me so I have to wait for the center to be done. I'm about to start digging out the old wood ....

 

[littleguydave]

So there is only one piece of rotten wood and it is by th hammer. The rest of the wood is very wet and slimy. I have the garage door open and the fan is blowing on hi to circulate the moist air out of the boat. I will run the fan all night and tomorrow i will decide if I need to replace the wood. I might just spray it with detergent and put on new flooring. The wood still holds screws tight so maybe when it dries I can proceed. This is my first boat and it is paid for so I don't care if it's perfect or not

anyway, so happy to see that gas tank. It is full, so I need ideas. I don't feel safe transporting it in 5 gallon buckets. Is there a special container I can buy to hold this much gas? I am so happy that I can start working on this fuel issue

This is my first boat so I have no idea what I am doing. Let me give some info
95 Crownline 4.3L v8

When I bought the boat it had a lot of issues. It would not start without beating on the starter, and the tilt/trim would not operate unless I beat on the pump. So I rebuilt the alternator and replaced the tild solonoids and motor. Now the tilt/trim works great and it starts up.

When I get the boat out on the water it runs good, but after about 20 minutes it will start to sputter. Sometimes it will make a loud "PUFF" sound and then start to stall. Usually it will start right back up and run for another 10 minutes before dying. So I took it home, added seafoam and ran it with muffs. It ran for 2 hours and never overheated or stalled. I had it slightly above idle and it burned a quarter tank. So I started to add non-ethanol fuel and I tried to keep the tank as full as possible.

Now I have the boat in my garage and I am rebuilding all of the wood. Since I have it open, I decided to do some engine maintenance. The first thing I did was look at the carb. I noticed that the flame arrestor was covered in debris and oil. It took 2 cans of carb cleaner to get it clean. I looked at the fuel/water separator and dumped it into a jar. This is what I see....

So this is where I am. Could this be why my boat runs like crap? I am about to add some fuel stabilizer. I want to put the new fuel filter on and run it for a day, then replace the filter again. I am also trying to change the oil and researching how to do the engine fogging.

The last 3 times I took the boat out to the dock I could not get it to run.

Flame arrestor covered with crap may mean "blow back" from crappy rings. Go buy you the cheapest 12 volt automotive inline fuel pump and several feet of 3/8" fuel line hose you can find. Suck all the fuel out of tank thru the new fuel filter. You may have to go through several filters. I don't know how big your tank is but the gasohaul **** will eat old fuel lines over time. . Hopefully, you can suck up all the crap that has accumulated inside tank and into filter. HOPEFULLY. I bought boat that had sat for over a year and was a mess. I finally removed the crap and water and was able to use and successfully burn fuel. Your carb's bowl probably has water in it. Pull off top and LOOK INSIDE. If still crapy you may have to rebuild it. If a salt water motor, they usually rust out before wearing out.

 

[littleguydave]

I am just going to remove the entire tank. I have a new fuel/water separator and a new fuel pump on the way in the mail. I will replace all rubber hoses and I am going to scrub out the tank the best I can. Hopefully I can get it emptied this weekend. I am a truck driver (cdl) and I don't get home until dark so I can only dedicate 30 minutes a day, and most of the day Sunday

You might check with local feed stores. They often carry and sell olive oil barrels that were used to import olive oil and not worth shipping back around the world. You can pump out the fuel in the tank. I wouldn't put any of it back in a boat. Too hard to walk back to your truck when something gets plugged up. Lawnmower, yeah.

Maybe an old beater car, a little at a time, after filtering it and running a bit of fuel water remover into it. *when you use a water absorption additive, the ethanol in the additive combines with any water in the fuel and sinks to the bottom of the tank. So suck a bit off the bottom and toss it. This not only removes most of the water but negatively, the water mixed with ethanol that is pulled off has sucked a bunch of the octane out of the fuel. This is the main reason an engine has trouble burning fuel that has had much water in it - the octane level drops way down in the fuel - like all the way down close to 70 octane. Too low to run without knocking and spluttering. So either mix it sparingly - in something other than your boat - or add octane booster to it. And make sure it is filtered.

There are a bunch of tricks to getting water out of wet wood structure. I'll bet @Woodonglass can offer a bit of advice there.

For transporting gasoline I think five gallon jerry cans work the best. They're easy to handle, designed for the job and are certified for transport. Also on the newer ones the caps don't leak like the old ones.
Flush them out and you can use them afterwards to fill the boat.
You are going to replace the rotted wood, right! That stuff tends to spread like cancer.

Yes I am replacing the rotten wood, but not the wet wood. I am just drying it out. I am sure it has been wet under the deck for a year. The boat has been garaged for 2 months and it is still wet. So after this dries I am adding the wood floor. So far I only see one piece of wood that has fallen apart. I am doing one section at a time do I have something to sit on while working

 

[littleguydave]

As for the 20 gallons of fuel, I am discarding it. I am not putting that toxin back into my boat. I am cleaning the entire system, and only using non ethanol gas. I will call it a loss and just spend $60 for new gas

 

[GA_Boater]

Good move on disposing the ex-fuel in the tank.

If the wood ever dries out, it may still be compromised. Maybe not apparent now, but the little heebie-jeebies are working on the wood and it will show up as rot.

 

[Hoosmatroos]

I think most, if not all, the wood is rotten. If it's wet that long you can bet you have to replace all. Most likely the stringers are rotten too. Sorry to say but that is what you have to expect.

 

[littleguydave]

I'll know by tomorrow I hope. I will make a call the best I can. I am going to do all in my power to keep what I can. I will replace the wood that is soft and if there are any easy cuts that aren't rounded I will do those too. Saturday evening I want to put the floor back down and carpet it so that Sunday I can start working on the carb and fluid replacements. I also have to do electrical work too because the boat has a bad wire somewhere that is constantly draining the battery. This entire boat is getting work

Go man go. You are traveling down a well worn path for these forums. You impress me as a person who can tackle anything thrown at you. Enjoy it. Not often you get to build your fun.

Agreed, gonna subscribe to this one.

 

[littleguydave]

After I leave the gym I am buying 4 of the 5 gallon gas cans. Any suggestions on where to get the best price?

 

[Rick Stephens]

If you are tossing the fuel, just get one if you can find a place nearby that will take the bad fuel. Or if you can burn it there. As far as cheapest, Costco, Walmart, any chain parts store.

 

[littleguydave]

Ok thanks, I will call the dump tomorrow. I went to Home Depot for 3 15 gallon cans. I went to use a hand pump to get the gas out and it was taking way too long. I worked all day and now it is 930. This weekend I am getting the tank cleaned and maybe replacing the hoses. The floor will also go down if the wood is dry and feels solid. I wish I could have gotten the gas out tonight

 

[littleguydave]

Got the tank out ans I am getting the gas out. I broke the piece that sucks gas out of the hose. I also need a new sending unit. Any suggestions?

 

[littleguydave]

Anybody know of a sending unit I can buy and the piece that sucks gas out of the tank? I am looking online now. I am about to soak the tank in a drain cleaner with water. I will let it sit for an hour then rinse. Tonight I will dry it out and once the parts get here I will put it together
