Re: Mercuriser 3.0 engine problem
When you were flushing it, water was coming out 2 little holes on the transom and not thru the center of the prop hub?
*. the impellor impeller how ever it is spelt was bad,,, New one went in today..
Ok when you look at the carb there is a fitting, that enters the carb, there is a fuel filter in that fitting.
*.Carb is being rebuilt again so I hope they check that filter
There may also be a fuel filter in the fuel pump, do not remove the fuel pump from the block to clean it.
What sort of pump did you just install?
*.Carter fuel pump,, I have a picture of it but cant figure out how to put a picture in a post here,, grrrrrrrrr ok I think I got a picture attached. somewhere in here of the fuel pump. lol
Did it have a bell on the top, with a screw?
*. It has a bowl on the bottom with a screw in it and a strap over the screw so you cant adjust it,, or does it have a removable filter in there,, the manual says it must be replaced as a whole unit its not repairable!!
Also there is a screen on the fuel pickup, it's the tube that actually pulls gas up from the bottom of the tank.
There is a one way valve connected to that tube on the gas tank it has a 90 degree angle, that has the fuel hose connected to it.
*. Ill look for that,, I wondered how to get into the tank,, I was going to siphon the fuel out and put in all fresh gas but the fill hose has a huge 90 degree fitting at the tank and I couldn?t get my siphon hose past that .
On a boat of this vintage, not uncommon for gunk and water to be in the bottom of the tank.
*. That was my thinking as well
The hole i use is the fuel pickup hole.
It allows you with one move to, clean the pickup screen, check the anti-syphon valve [one way valve] and pump the dirt and water off the bottom of the tank.
Follow me so far?
*. Pretty much,, that anti siphon valve how do you clean it and the screen? Just blow it out with air??
If the ant-syphon valve gets stuck it won't allow enough fuel into the carb.
*. OK ill take it apart and clean it and blow it all out,,,
Also when the hole is open allows you to check the vent hose.
Bye blowing thru it and seeing if any little critters are living in there?
If the vent gets clogged it causes a vacuum in the tank thusly not allowing fuel to leave the tank, cause air can't take up the space.
I went thru this long post for a reason, if water is in the tank you can do a bunch of stuff once the hole is open in the tank.
With all the fuel filters clean cause now you know where they are, and the hole open cause you found water in the tank, you will need to pump out the bottom.
Heres how, with a cheap electric fuel pump bought at any auto store 12v,15 dollars tops, and 10 feet of clear hose and 2 clamps you would be ready to pump.
*. Is this like a portable fuel pump ?? that I would ask for in the store?
Cut hose in half install on both ends with clamps, stick one end of hose into the gas tank way in the back corner, and other end in a clear bottle, and the bow of the boat as far up as you can get it.
*. What ya mean wayyyy in the back corner??????
You should lift the drive to allow the bow up as far as you can get it, a hour or 2 before you start to pump.
This way the water has a chance to settle to the bottom.
Hook the pump up as far away from the battery as possible, and pump the water and gunk out of the tank when you see fresh fuel in the clear hose entering the clear bottle stop.
Now you have the tank clean.
*. Okie dokie that a good thing lol
Every couple of years do it again, that little electric fuel pump can be carried on the boat and if you run into the problem that the fuel pump ain't working you can hook it up and pump gas to the carb bypassing the mechanical pump.
It gives 4-6 psi just like a mechanical pump.
*. wish I had that the other day lol
See no sea tow if the pump goes on the water.
Another trick, see how that alternator belts goes on, must pass the mount?
*. THIS IS FUNNY YOU ASKED THIS ONE,, I was asking this also after looking at the engine I was thinking id like to keep a spare belt but how in the heck do I get it on,, funny you mention this lol
How would you change it on the water, if it goes?
*. That?s a good question,, how to you get the spare belt around that engine frame or what ever that is,, looks like to me you have to lift the whole engine up ??
What i did was in my driveway put one around the mount twist tied to the mount, so in 5 minutes and a long screw driver and a 1/2 inch open flat wrench, be done with it and enjoy the rest of the day on the water.
*. HOW DOES WOLFY GET IT AROUND THAT MOUNT?
So far in you onboard small tool box, mine is plastic, you need a 1/2 inch flat wrench, other side 9/16ths.
Electric fuel pump with long leads and small clamps like on a battery charger. You probably figured to do it anyway.
Long flat screwdriver length of the box, phillips head screwdriver.
Small flathead screwdriver.
2 rolls of good black tape.
*. I got that pluss a roll of racing tape,, which is better then duct tape
I used a roll of black tape to tape up my large water pump hose when it split down the side, it held long enough for me to limp back in to the dock.
But now i keep a spare one on the boat that u shaped hose.
I have a pair of channel lock pliers biggest pair i could fit in the box, a small hammer.
Let me explain about a hammer, don't hit nothing with it.
*. Awww shucks lolol
A hammer in the wrong hands will destroy a boat motor faster than anything.
*. Yep never ever let your xwife hold your hammer not a good thing lol ouch
I'ts used to tap the starter maybe if the bendex hangs up.
*. Have already had to do just that
I's used to smack a kid in the head ,or a giant fish that?s thrashing on the floor.
*. I?ll juss throw the kid over board and I aint got a big giant fish yet lol
The handle could be used as leverage on the alternator if the belt goes.
Say the bolt is so tight on the alternator just won't budge, tap the wrench with the hammer.
I keep a cheap test light with a bulb in the box.
Good for checking for a no start condition.
Also 3/8 flat open wrench, it fits my manifold plug.
Regular pliers wrapped handle with black tape, i wont go into it here but saved my life once, in the service power was supposed to be cut, bye one of my minions, and i wrapped both ends of the pliers with black tape, saved my life.
One pair of wire cutters.
One pair needle nose pliers.
Oh a knife, the one like Stanley that the razor slips in and out.
And a heavy guage 2-3 foot single stand wire.
*. I have some 4 gage stranded wire that was used to run my 3500 watt inverter will that work???
*. 1st thing I did when I got the boat was put together a good ammo can plastic tool box for the boat,, tester, hammer , a stainless screw nut and bolt organizer trays with the lid on it which I also keep electrical connectors in there also,,, except for the wire you mention and gas pump,, ill add both those ,, great idea for both.. I also keep under the cabin bed a hand carry socket tool set I bought for the boat and mask, fins, and snorkel,, in case I have to go looking for giant fish lolol
I'm sure you can come up with more stuff for your box.
I'm sure i'm boring you so i'll end it here.
*. Naw ya don?t bore me at all,, I appreciate your help and your advice?
