Help for a co-worker

10 posts in this topic

Last year I assisted a co-worker in purchasing his first boat. He ended buying a small 14' with an 18hp merc (mid to late 80's model).

I went through all the winterizing with him and all was well for most of this year.

The other day he tells me that it's not running right at all. So I went over the obvious stuff with him. Still no good.

He hired a guy off hsolist that will come to your place and work on marine engines.

This guy ended up rebuilding the carb and also noticed a banged up prop, so he had that rebuilt as well. That was $250 total.

Not sure about the pricing on that but anyways..........

He took it out the other day and the same problem exists.

It starts up perfect, but when he opens the throttle, it misses bad, pops, spits, sputters. Then if he opens it up fully it catches and runs ok.

He called the guy back up and this guys says, "well, it might be the fuel pump".

I don't want to get too involved, but I told him I would try to get some suggestions for him.

Thanks

That's part of the problem with Craig's List, you don't know what you're gonna get. Guy shoulda gone out and tested it. I would think he should charge less to put a fuel pump in. On the bright side, he did get a carb rebuilt and that never hurts. I've had bad mechanics that didn't backup their work, then I've had awesome ones. Kinda hit or miss.

What does this mean? When he gives it a little gas it misses.....but when running wide open it runs good?

If the guy did rebuild the carb, it could be something with the ignition. I had a similar issue with an 85 Merc 20hp.....motor would start easy but after idling a little it would start to miss. Ran great at WOT. I replaced the coils and that solved my issue. Not sure this sounds like the same thing.

Rebuilding the carb should take care of any "fuel pump" issues. There is no actual mechanical fuel pump on the mid 80's 18/20/25hp Mercs.....it's all a part of the carb.

Has he run it with the cover off and noticed what is happening in the fuel bowl (is it running dry)? Has he checked the fuel filter? Gas lines all good with no air leaks? Gas tank breather open.....I know some basic stuff....but all things I have seen cause issues on the mid 80's Merc we have.

Did he get the old parts back from the carb rebuild? Have you checked the compression by chance.

Have him pull the choke when he runs the throttle up and see what happens - if it picks up it's a fuel restriction issue, and there for something in the carb yet.

If they guy did a good job cleaning the carbs it sure sounds like an ignition problem then.

Yeah, I was thinking something electrical/ingition as well.

I will pass on the thoughts to him.

Thanks

Darren, If he is absolutely sure the carbs are squeaky clean, then I'd be looking into ignition, mainly timing.

So, is this "expert" going to keep replacing parts and rebuilding components until he finds the solution? Maybe too late now but I'd be inclined to push some kind of warranty in this situation. He obviously either mis-diagnosed the problem or failed to do a good job and I'd certainly try to hold him to it but like I said, it may be a little too late now that the process has begun.

Here's an update, be brought it in (not sure if R&R or not). They rebuilt the carbs and she's running good.

He's not too happy about paying for a phantom rebuild the first time though mad

    • The Schrillary reich didnt compromise Bernie? And when hasnt the biased media compromised an election in recent memory? Nick is a hack and consistently posts 2nd grade propaganda, hes sold out to the party. They've been exposed and are resorting to extremes.  They went all in with obama and got called, he had far more to do with the outcome of the elections than anything  leaked by anyone.  Now its the fake blame game, humorous to say the least.   Snowflake butthurt apparently leads to desperation.
    • Really??? Catfish is my favorite fish.
    • I suspect you haven't visited this year or seen the reports.     And, for the record, I didn't say I was catching "tons" on Mille Lacs, but it was the best lake I've visited in the last two years.  And it wasn't even close.    
    • I think Schells is Minnesota's oldest brewer, so they must be doing something right.   I know some guys from New Ulm, and they all drink Schells.   That's how I got turned onto it in the first place.  Never got burned out on it, though..
    • Sink or swim? I am sure that some of you have heard that if you put seeds in water the ones that sink are better then the ones that float. I have heard this from the old guys but I have never tried it myself. Well I found myself with some radish seeds and I decided to pour them into a cup of water and sure enough about half sunk to the bottom while the rest floated. I got out a bowl and filled it with coconut husk planting mix and put the floaters on one side and the sinkers on the other. I am now waiting to see what side comes up first or if both sides will come up at the same time.   Any comments? Has anyone else heard of this and does anyone check their seeds before planting?
    • Maybe he's just hungry............    
    • Catfish!! I haven't had that in about ten years! Dang, that looks good! 
    • All day long you sit here and demand answers from everyone else but you never answer anyone else's questions. I wonder why that is?    
    • I would guess even Fletcher would say Stall has passed all expectations. I will give credit to Fletcher for building this team from absolute zero, we had almost no skill or prospects when he took over,  sure it took longer than we wanted but right now it is worth it. No doubt luck can play a roll, most GM's don't have a Suter, Parise, Stall & BB fall into their lap but quality drafting and development are also paying big dividends right now. We also have a lot of high end prospects that can fill in for the vets in the coming years. A cup is still a long ways away but this year is probably the best NHL team the state has ever seen.
