Author Topic: Season ends with another problem... (Read 9982 times)

Well, Last weekend I went up to the lake for my last outing for this season. I was able to run it twice on Friday, Boat is still not running correctly. When you hear it from back of boat sounds like it is miss firing. Seems to be running rich,Based on the smell. When I hammer down on it, if falls flat on it face then catches up and goes. When I give it full throttle it loses power. Then when I back off it gains its power back

So I wake up the next morning ready to go out for another spin and I get down to the boat, hard to see in the pictures but the water is just over my exhaust tips inside and up to my kick board..My life vest was floating....Ran the bilge got all the water out, had my dad tow me back to the dock and pulled it out. (didn't want to start it till I made sure water didn't get in the oil pan or cylinders). Found were the leak is. I have a hole in my main bellow for the out drive.

Looks like the work continues.

Wow Shrom! Glad it didn't sink!

Have the exact same problem with my intimidator. After the first shake down run I pulled the drain plug. What do you know, water on the inside of the boat. How did that get there? PO said mechanically it was good to go. Go were? Good thing we were only out for 45 minutes. I guess it is the least of my worries right now.

God luck with yours Shrom.

And that is why I put flotation back in my cvx-18!!!

Hopefully everything is OK with the motor/drive Shrom. I launched mine without putting the plug in this summer and didn't realize it until I was out in the bay with water creeping in front of the back seat.

My boat won't be put into the water next year w/o an automatic bilge pump.

Could it be either the fuel pump or a clogged fuel filter? I've read that that can lead to the hesitation you're having.

Glad it didn't sink on you as well. The first time I ever launched my boat a week after buying it in 2007 I completely forgot that you even needed a plug! Luckily another boater on Lake Elmo said, "Hey buddy! Your boat's sinking!" It was before we had even taken it off the trailer so luckily we just pulled forward and embarrassingly put the plug in!

Unfortunately I know boats can take on A LOT of water without sinking, like coming out of the drain hole like a garden hose the drive home and for a another 8 minutes in the driveway. Doug is probably a good authority on this matter as well.

He he, me too! I refer to it as my "bilge rinsing incident", seemed like it took 20 minutes to drain!

Sorry to hear about your problems, Shrom. Had to be most disheartening. I don't know squat about inboards or outdrives, but between Rich and the rest of the gang I'm sure you'll have her sorted out before spring.

I am pretty sure forgetting the plug or partially sinking our boats has happened to all of us. Hopefully your boat dries out soon!

The fuel problem sounds like maybe a accelerator pump. Not sure if those have idle mixutre screws or not but I had a similar problem on my 2V Rochester and adjusting the idle mixture screws took care of it.

Shrom - Any idea how old the bellows was?

If your fuel tanks are floating around behind you and one of 'ems full, ya know yer in trouble ...

All that remains:

Not sure how old the bellows are. My only guess is they are original. I'll try and take pictures of the process if I think of it at the time.

Lucky for me I got to practice on replacing bellow on my brothers Carlson a few years ago. So I have some what of an idea on how to do it.. All I remember is it was a pain, with all the tight areas.

I too have forgot to put the plug in once, But never got the boat off the trailer (Thank goodness) I'm not really sure on why it is not running correctly so I am open for idea's. I guess I'll have to check my fuel pressure. Make sure that is good. The carb is new and possibly could just be adjusted, but The problem is every time i go out boating everyone just wants to enjoy them selves...which is great but doesn't leave me much time to mess around with the carb adjusting it. Seems like every time I go out just for tuning. I find something else wrong with it that puts my off the water.

No. Quite bad actually ...

Wow, I was feeling bad on my last trip out, but nothing compared to your luck. While my son was loading the boat the bunk broke in half, not a big issue except the trailer was purchased new last summer...go figure.

However, my wife just got home with our Pacifica and someone backed into the grill and hood, and then left...with a $1000 deductable maybe I'll just buy a lebra...

My 2002 Toyota Celica has had bodywork three times. The first time I forget that our other car was in back of it. The other two times my wife sideswiped one side and my son sideswiped the other side. Nothing like keeping it in the family.

Shrom,
knowing that the transom was recently replaced on that one, and the fact that service records show that the boat was always an "at whatever cost" example, I think that the bellows may have been replaced at some point, but may have been damaged or improperly installed along the way. Not that it matters now... Anyway, if you want to replace the bellows I'd be happy to come over and offer a hand, and as far as the motor, if you want to get it out again this year, I'll go out with ya, we'll run it hard for a while and then check the plugs. White is lean, black/wet is rich, and tan will leave us looking at ignition condition, timing, etc... But, nothing beats a pair of ears hanging over the transom listening to it all through the rpm's... But, if you regain power when you lift off the throttle, you are closing the air off and increasing the fuel ratio, leading me to believe that it could be a fuel delivery problem, but, not necessarily. If it blows black smoke under a load, then it's rich... Let's get it out and play!

I may have posted this once before on this same topic. My 18 had the same problem, exact. Ended up being my secondary needles. They were far to restrictive. 0.824 was the dia. Mercruiser service bullitin called for 0.547 dia. I ordered three newsets of progressively smaller needles starting at 0.547. I started at the 0.547, ended up at 0.527. Wow what a difference. Two completely different motors. At $12 a set I couldn't go wrong. this was for a q-jet.If you happened to have the same carb and want to try different needles I could mail you a set I'm not using, it's worth a shot. Hopefully this helps.

Thanks, I would take you up on that offer but I have an edlebrock carb on it now. One of these days I'll have it running correct.

Wex, your probably right Good chance that it may have been replaced at one time. I may have to take you up on the helping offer. Then we might be able to get one more run in before the season is over.

wexrocks · « **Reply #19 on:** October 14, 2011, 10:19:48 PM »

Shrom,

I am pretty sure that I will be getting some of the metering rod/spring kits for the Edelbrock's, so I can tune in the 383, so I may be able to offer some pieces to get that thing dialed in just right (if that really is the issue). you know I'll do whatever I can to get my other favorite Carlson on the river running tip-top! any excuse to get out on the water!
