Rain, rain, rain. Didn't get to take the boat out today.

I did check for a fuel leak again to make sure the boat isn't going to go up in a ball of flames. With the new spark plugs in (this is with the engine turned OFF)...I pumped the primer bulb until it was tight. Then I pumped it a few more times. The engine is tilted and I still notice some fuel dripping slowly near the front of the engine (bow side). I guess that is the carburetor? Should fuel drip slowly from this with the engine turned off, tilted and after you pump the primer bulb several times?

I guess the fuel has to go somewhere, but should the carburetor leak like that? or does it have some overflow leak built-in? I unplugged the fuel line from the gas tank to prevent more leaking, but should you have to do this?

send some of that rain our way...getting winter grass and food plots out...lol. Once the primer is tight don't continue pumping. This can mess up the float in the carb if you pump to much. The float has a little needle on it that plugs the fuel inlet when you pump the primer or when a fuel pump is pushing fuel...I think those fuel pumps are only rated at like 1 to 3 psi...is this right you guys?? Your hand will put quite a bit more pressure on the float than that. You may need to rebuild the carbs...float and needles anyways. Let it set and prime it again later and when it gets firm quit and see if fuel still comes out. If not maybe its okay. Can't wait to hear how it does..good luck!

The tenson, man would you brave the rain and run the thing?


If your motor is tilted and there is fuel in the carbs it will leak out, floats are in an angle and wont seat the needle valve whitch allows fuel to run out of the body of the carbs , it will come out the air intakes on the carbs.

Ok, well that makes me feel better that fuel can leak out of the carbs normally.

Believe me, if the lake wasn't so far away, I'd take it out in a monsoon. But, it's so far away, you have to make a day out of it.

I'm wondering if the previous owner didn't know a lot more than he was letting on. Maybe that bank was dead and the plugs were pulled to allow those cylinders to free flow. Before you go putting those plugs back in I would perform a compression check. Someone could have installed a blocking plate over the intake side to seal off the air and fuel. That would explain the lack of it blowing up. If you put the plugs back and the intake is sealed on that side it might not crank at all.

I'm new to boat engines but I've been doing shade tree auto for 30 years. I've seen some weird stuff. I once bought a 52 Chevy that as the seller put it "needed a tune up". Turned out the number five piston was snapped off and sitting at the top of the cylinder. The rest of the piston rod had been removed as well as the push rods. It still ran pretty good but it had a very defined miss at idle. Since this engine's history is unknown, I suggest proceeding carefully.

Are you sure you didn't just recently tick someone off and they sabotaged your boat?

I was wondering if there might be a reason that someone would intentionally leave those 2 plugs out. I will keep this in mind when I try to crank it next time I take it out.

As far as sabotage, we took the boat skiing last saturday and parked the boat at about 8 p.m., I got up and took the engine cowl off the next morning and noticed the missing plugs. So someone would've had to have removed them that night. I doubt anyone did this though.

I wouldnt count on that. we had someone steal the prop off our boat ( while trailered at our campsite ) we were sleeping 40' away went to put the plug in the following morning a sunday of course last day of vacation NO PROP, NO SKI, NO FUN !

Re: Fuel Leak + No Spark Plugs but runs great - help - 115 HP

MAN that stinks, takeing your prop.

After Katrina we had sooooooo much looting here that the Gov.passed a new law. If you see someone on your property or breaking into anothers property or a bussenss you can flat out shoot them, you dont need to see a weapon or have them shoot at you first. In the year and a half this law was put on the books there has been only one case where a guy shot at people breaking into his car, we were expecting to see more cases but there has been only ONE. The crime rate droped in a matter of days in Mississippi

the two spark plug holes is where the fuel's coming from. you have no fire on that side though. if you did it would have went boom a long time ago. engine that old with i'm sure original plug wires, the coil itself wouldve arced through the old wire straight to the nearest ground. (the mounting bolts for the coils)........now really.....is this a joke?

Re: Fuel Leak + No Spark Plugs but runs great - help - 115 HP

so have you put the plugs in it yet?? I'm axious to see what that thing will do...32mph on two cylinders...I bet you'll get 45 with all four...this is one of those stories that you hear and you know deep down if that were me, I would've blown up, sunk, seized the motor, or something BAD would've happened...lol. I have a friend that has a dodge cummins just like me...I am maticulous about my truck...he never changes his oil, greases, or anything unless I'm around to tell him to...and his truck ALWAYS goes....with my luck if I didn't change my oil one time when I normally do it would probably throw a rod...lol. I know there are some out there that know what I'm talking about.

i heard that!!!!!

Man, you need to take a sick day when its not raining and run that motor.

I cant hold my breath anylonger.

Haha, no kidding...I think Saturday will be the day.

Re: Fuel Leak + No Spark Plugs but runs great - help - 115 HP

Just out of curiosity, have you done a spark check on that bank? Might want to verify the ignition is actually working before you go to the effort of taking it out.

Re: Fuel Leak + No Spark Plugs but runs great - help - 115 HP

No, I haven't...is that something you can test without special equipment?

 

[iwombat]

Re: Fuel Leak + No Spark Plugs but runs great - help - 115 HP

You'll need a spark tester, but you can get one for about $10 or make your own with nails and a piece of wood.
