Carburetor issue, advice needed!

Hello everyone. I am new to the forum and trying to help my dad out with his boat issue. I am a DYI auto mechanic, so he asked my advice. He has a Glastron fish/ski boat that has the Volvo Penta V6 motor. I believe the boat is around a 2000 or 2002. He was having issues with his boat running rough and he had someone replace the carb since it was the original. The refurbished one that was put in leaked really bad so they sent it back to the company who rebuilt it, but it still leaked. So now my dad is looking to buy one new. Is this the best option at this point? (Link below). Seems like an expensive price for a carb, but maybe there is someone else here that knows a better part of place to buy?

Thanks in advance! :)
 
That is far too much for that Holley carburetor. You can do much better.

You had the OEM over-hauled..... it leaked.... you sent it back..... it leaked again.
Send it back one more time, and demand that it work correctly this time around.

Well, the OEM was replaced with a remanufactured one. And THAT one leaked. And they gave the OEM one as a core, so he no longer has it.

Is there any better place to buy a new carb like the one I posted?

Are you sure it's a 4 barrel?

My '08 4.3 GL-J is only a 2 barrel.

All I know for 100% is that the part number on the original carb was VLP3858331 and I am trying to find it cheaper than 900 on the internet. I do not have the physical carb with me so that's why ID'ing it has been so difficult.

Thanks for yalls help and bearing with me!
 
I have a different take on this.... Most rebuilds are a mindless swap of a set of parts. If that fixes your problem all well and good. The art (learned by lots of sweat) is to figure out what the core problem is and fix that issue.
My question... from where does it leak? and under what conditions?

i agree!

the leak on the remanufactured one that was put on was coming from the front bowl near the accelerator pump. this was all the info i was given. they took it off when it leaked and had another remanufactured one put on and it leaked as well. there is a chance that there is something else going on but I have not worked on this boat myself, so it is kind of hard for me to tell. we are basically trying to find the best available carb and try it to see if it has the same issue as the previous ones that leaked.

What is the model number of the motor and drive? Without knowing displacement we are just guessing what would be best for fuel delivery. If your dumping too much fuel into the cylinders to burn it will wash down into the crankcase and contaminate engine oil.You need to know what engine your running in order to determine the proper carb and jet sizes. My take on this is do as much research as possible before spending any more money. Guessing dont seem to be working very well!

It is a 4.3L V6 volvo penta motor.
 
"Calibrated for OMC & Volvo (4.3 liter) V6 Marine Engines"

Sounds like a winner to me. Shouldn't be too much if "calibrated for".

this one says its for the v6, but isnt 600 cfm too much?

Your 4.3L engine requires approximately 305 cfm 100% VE at 4k rpm.

When I did the CFM calculation earlier....... I did so to demonstrate that often we shoot for more CFM than what the Marine Engine actually demands -vs- the auto engine.

The 600 CFM carburetor will be just fine and will meter the fuel throughout the range...... but I'd not go any larger.
