Greetings all! This is one of my first posts so bear with me and any and all help is most appreciated.
In addition, this is going to be a HUGE post to explain everything fully.
First things first.
Engine:
1990 ~ "something" 225 Evinrude Ocean Pro with a new power head 2 years ago.
Problem:
The boat runs fine but when I come off plane and comes to the dock, sometimes the boat "stalls" as soon as I take it out of gear to throw it into reverse to stop my forward motion. It will idle (1000 to 1300 RPM in gear) and troll and do a "booze cruise speed" no problem but as soon as I get to the dock and pull it out of gear, SOMETIMES, its "spits" and stops running.
Before we go any further ....
I just picked this boat up last Thursday. It is a used boat. The boat had been sitting on the dealers lot for a minimum of 6 months before I touched it. I brought it home and did a few things to it BUT, I never drained the fuel tank. I never changed the fuel/water seperator filter canister. I never changed the plugs. The boat was registered in Florida last year so either it was in the water last year or they bought a 2 year registration sticker 2 years ago and it was sitting for a real long time, minimum 1 1/2 years.
Please don't chastize me as I was thinking "how bad can the gas be?" but I never checked it until last night. Please read on as the "gas checking" is part of my final question. And I'm usually a million times more diligent than this, I just screwed up....
Friday morning, I ran the engine in the driveway and it ran fine. I let it run for about 5 minutes. I put a board about 12 inches behind the prop to stop the water from from the exhaust from shooting into my garage. After the 5 minute run, there was a lot of oil or "oily resudue" all over the board that shot out of the exhaust of the prop.
Saturday afternoon, we took the boat out. Before we left, I put 15 gallons of fuel in the boat. We kept the boat in the Banana River in Merritt Island just so I could check it. From the boat ramp, the boat took off fine and ran well. I brought the boat down and checked my gages. Water pressure, engine water temperature and volts were all fine. I idled for about 5 minutes and then tried to run again.
(Now this next part is important to mention because it goes along with my theory as well as being part of my final question.)
When I gave it gas again, The engine started to "shake" pretty bad and I brought it down. It idled fine but it was a little "shaky" like it was (for lack of better explanation) "coughing", but everytime I tried to take it on plane, it shook and wouldn't go.
We "booze cruised" for about an hour at 1000 to 1300 rpm's until I decided to take it on plane again. It went on plane quite well this time but then I took it off plane and we idled for about 500 yards to an on the water restaurant. As soon as I took it out of gear, it spit, and died. At the restaurant, (Important thing to mention) the boat was rocking and rolling as the wind picked up and the waves got a little crazy. We left and we took the boat home and parked it behind the house.
Sunday morning, before we left the dock, thinking the old plugs were "fouled", I put 6 new plugs in. This was the first time I put plugs in the motor. Then we took the boat out again. Once again, it idled fine all the way out to where we could pick up and take off which usually takes about 10 minutes. It ran at high speed great for about 5 minutes and then I brought it down in the no wake zone.
To get to the ocean in Cape Canaveral, you have to go thru a "lock". As soon as I brought it out of gear to wait for the lock to open, it "spit" and died. It starts right back up, but it will spit and die time and time again. We idled all the way out the port (about 5 miles) and then started trolling the main channel all the way out to approximately 2 miles out, 10 to 15 miles of total trolling and back. When we were done, I picked up and ran. It was "coughing" a little as we were running but I figured the plugs were loaded up.
As soon as I came to the lock to go back in and took it out of gear, it spit and died. As soon as the lock opened, the boat would not stay running. It would start and then die. We thought it might be out of gas! I squeezed the ball, started it and immediately put it in gear and it ran, shaky, but it ran and idled. It started and died about 5 to 10 times before I could get it running again.
We idled about 300 yards and then picked up and ran into our canal and then idled back to our dock. When I took it out of gear at the dock, it spit and died.
Remembering what someone said on this forum, Sunday evening, I took 2 gallons of gas, 5 ounces of 50:1 oil and a bottle of Techron and mixed them together, put the fuel line from the engine in the gas and ran it in idle until the motor ate all the gas mixture. It idled hard and spit when I started the motor but by the time it ate all the gas, it was running pretty sweet.
Monday, on my way home from work, I picked up another 2 gallons of gas, added 5 ounces of 50:1 oil and put the engines fuel line in the gas can and ran it back to the boat ramp and pulled her out. It idled out great, it picked up and ran great but as soon as I hit the dock, it spit and died. In addition, as soon as I took it off plane, it was running a little "rough' and was a little "shakey" at idle.
At home, in the driveway, I hooked up the water and ran the engine, with what was left of the 2 gallons of gas and 50:1 I picked up on my way home from work with the board behind the engine again and there was NO oily residue this time.
So last night, in the driveway, I pumped the ball to get fuel from the boats gas tank into a clear plastic 2 quart bowl. Out of 1 quart of gas, HALF was "green" colored gas (my 50:1 lube that I add right to the gas is "green") that was floating on top and the rest, on the bottom of the plastic 2 quart bowl was thick, gelatenous brown liquid.
I poured off the green gas the best I could into another bowl and the leftover brown liquid smelled JUST like varnish. It looked like a combination of "clear, small, flat jellyfish and something close to water" but mostly, it was just a thick liquid that smelled JUST LIKE varnish.
I drained out 5 gallons of gas, checking it every so often by draining a quart or so into the clear plastic bowl and inspecting it before the gas finally ran clear.
In addition, after the gas started to run clear, I squeezed the ball hard and drained out another 2 quarts thinking if I forced the gas thru the line, instead of it just draining, I would get any remaining varnish. The gas in the 2 quart bowl remained the "clear/green" that is was after I drained the 5 gallons.
So now a couple important things to mention ......
A. The boat received new 85 gallon plastic belly tank a few years ago. When actually? I don't know BUT, the gas tank now has the pickup in the FRONT of the tank.
B. I am thinking that when the boat was rocking and rolling at the restaurant dock, the NEW 15 gallons of gas helped "wash things" inside the tank and mix them all up.
C. BECAUSE the pickup is in the FRONT of the tank, when I took off and got the boat on plane, it was running on "good' gas but when I was idling after I laid it down, it was picking up the "varnishy" gas as the boat was sitting level in the water. I think I can certify this is happening because in my driveway, the boat is sitting with the front of the boat slightly angled downhill so when I was draining the tank THRU THE ENGINES GAS LINE, it picked up the varnish that had run forward in the tank. When I tried to pick up and run after idling, the gas in the line was all varnishy thereby making it "spit" as I was tring to get it on plane.
D. Last night, I pulled the "inline fuel filter" from the fuel line inside the motor housing and it was clean. I blew thru it with no blockage whatsoever.
E. My tanks dimensions are 30 inches wide by 48 inches long and (after I pulled the fuel sender off the tank and measured the remaining depth of gas in the tank) there was 3 inches of gas. (I believe there is 2.5 cubic feet of gas left in the tank)
So my question is.....
1. How badly did I screw this motor up if I did at all?
2. Are the jets in the carbs all clogged? Because the fuel filter was "varnishy" and there were no large "chunks" of any type, I am thinking that the only bad "varnnishy" deposits were going into the carbs and engine. Could they still clog the jets?
3. Is the above possible clogged jets the reason the motor spits and dies at the dock?
4. How do I correct the above problem? Can I correct it with another Techron treatment?
5. Even though the fuel ran clear after 5 gallons of draining, Should I still drain all the gas and discard it?
6. Should I "decarborize" the motor? (I read about doing that on this forum as well)
Thank you to everyone who writes and helps.
