We took out our "baby boat", our 16' '90 Quantum fishing boat with a Force 50hp OB, yesterday morning for some fishing on Clark's Hill (sometimes called Strom Thermond Lake.....but not by old timers, dammit!!!)


During our brief ownership of "baby boat", it has so far been a very nice experience. Got it for mega cheap and it's been almost trouble free, amazingly enough considering some of the sentiment expressed in places about Bayliner built boats and Force OB's.

Until yesterday, the motor cranks up first or second try after trailering, first try after that start. But yesterday, a different story. Took a few starts to get it running and it was running sort of ragged....but nothing terrible and I thought it may have been some bad gas (bought the tank of gas from a different retailer than I usually do as we were up there at 5AM and our normal gas station was closed then.)

We cruise across the lake from our launch point.....begin fishing but I now smell gas.....a lot of gas. Look behind the boat, see a sheen of gas on the water.

Damn! But I don't see where the gas is from, so we decide to go back to the dock and trailer her. Cannot do anything on the water.

It's running worse and WOT speed is down by almost 5 mph from normal.

Trailer the boat, pull out and take a look. Gas is pouring out from the lower cover of the motor. Pull off the motor's upper cover and discover this sitting in the bottom of the motor's lower cover:

And the carb looks like this:

Honestly, I've not seen a fuel bowl fall off a carb before. And I'm also surprised that the motor even managed to run, much less do 26mph, albeit while running like it had water in the gas.

I did check, after getting home, the threads inside the carb where the bowl's bolt screws into.....and the threads are intact, as are the bowl's bolt's threads. Guess it just loosened up.....

So maybe this was just the boat wanting the carb to be rebuilt, something I was planning on doing in December. Suppose sooner is better than later.

So, how's your weekend going? ;)

had a nice "cocktail cruise" with my wife yesterday afternoon; first day of sun in a week. A little on the cool side, but pleasant.
Today, raining again--on the stuff I put out to dry from getting wet in the basement!

wow,l yea that will cause a fuel smell for sure, Im shocked you were able to find the bolt and the washers... some of those carbs have a small spring that sits under the main jet... i would look to see if yours does and if you can find it...

I thought it was strange to find them just laying in the engine, too. Guess the boat's just trying to keep itself in the family....LOL!

As far as the spring mentioned, I don't see one in this parts diagram of my engine's carb:

No spring in your carb bowl. Make sure you put a dab of thread locker on that bolt or at least recheck it from time to time.

Our weekend was awful also. First we got to the boat and brought a couple of friends along. Loaded everything up and both the engines fired up on the first hit of the key.

Boat ran great and we spent the day at the island floating in the giant raft and enjoying a couple of cocktails. The weather was perfect and the water wa 83 degrees.

Left the island at 5:00 and met up with two more friends at the waterside restaurant. Live band, dinner, dancing, and a couple of beers. Headed back at 10:00 pm. Put the boat back into the slip and hosed it off. Headed back to the house and was in bed before midnight.

Oh, wait...maybe my weekend didn't suck at all....:D

I thought it was only called Strom Thurmond by South Carolinians? :) :) :)

Glad you didn't have an engine fire! That would NOT be fun. My weekend was great! Thanks for asking.

well I had gas problems today also.Got the boat loaded up an started to leave when I notice I was just about out of gas(had over a 1/4 tank when I got to the ramp).So I head straight to the gas station an pull up next to the pump an get out of the truck an get a large smell of gas an see steam coming out from under the truck, a gas line had busted an was spraying gas all over my exhust system.Had to cut a 10" piece of fuel line from the boat to repair the truck, got lucky they were both 5/16 fuel line, and got real lucky it did not go up in flames...............

Not any longer, at least officially. Lots of signage on the GA side by the Corps of Engineers are labeled Thurmond Lake now. Sad, really, that SC could change the lake's name like that.

I grew up on Clark's Hill Lake. Spent every summer up there while growing up. Love the lake.....hate the "new" name, though.

Had to work all weekend, so the boat stayed in the barn. Othewise ok, until yesterday (Sunday). Headed to work and the car started acting strange. Limped it home this morning. After 252K miles, I think the rear catalytic converter is clogged up (Chrysler FWD V6). Just looked it up online, gonna run me a cool $500! IF that is what's wrong with it. :mad: Oh, well, can say I got my money's worth out of it :rolleyes:

Our '02 Blazer had the same problem a few months ago....unfortunately, the problem reared its ugly head just after I'd picked up a boat and was on the interstate in Atlanta. What was supposed to be a 3 1/2 hour trip turned into 12. Truck wouldn't run at any rpm beyond 1500....it was a slower than normal drive back, needless to say.

And the cat repair was just over $700 from a shop. But we got 210K miles out of the original, so like you said, got our money's worth out if it.

Sucks, though, doesn't it?

You should do a compression check. You might have caused some scoring on the bottom cylinder as it was starving for fuel/oil when the bowl fell off.
