Would you pay for this?

My 135 Optimax went in the shop for a faul finding session the other day.

Basically the engine would turn over but never fire. Almost like it was getting fuel.

I've checked the tank for kinks in the hose and air locks and it works fine. The fuel in the water seperator looks fine as does the stuff in the hoses. No loose connectors or the like.

So a bit stuck I took the boat to my local Mariner dealer and they spent 3 hours looking over the problem which they eventually diagnosed as a loose cable. I asked them to give it a good check and run on the muffs for a fair old time. He said he did this and he ran it up on the muffs when I went to collect it. It started first time and ran for less than a min.

I've just tried it this afternoon and less than 100 yards from the end of the slipway the same problem happened again. I've now changed the pugs which did cure it for a 40 sec run, before spluttering and dying.

I don't think it has been plugged into the diagnostic software either!

So
a) does anyone have any ideas on the fault
b) would you pay for an subsequent fault finding on the same fault after failing to find it and then not testing it despite the customers requests.

What are 'muffs'?

Flush Muffs for running it of a hose. They fit over the water intake so you can run the engine out of the water

Also used for flushing out the seawater

The old plugs were a mixed bag really. Most had a bit of soot and two of them had a bit of oil on them.

I've checked the fuel from tank to water seperator, to bulb, to diaphram pump, to electric pump and its all OK. I can't follow the fuel any further as the lines go into the fuel filter and the big steel vessel, (vapour thingy!)

I've not checked the diaphram pump itself though.

No I wouldnt pay for it. Had the same prob a couple of years ago. Bloke said he would fix it in 2 days, two weeks later he hadn't! Picked boat up and he tried to charge me for 14 days storage, the reply involved some 4 leter words!
Turned out ot be a dodgy wire which I fixed myself.
Yours does sound like fuel tho'. Run it in a tank if you can, much better for diagnosis than muffs. Where abouts is your boat based?

Right just to clarify;

The engine went in for repairs, it was returned to me fixed as a loose electrical connection had been found. (In addition a worn hose was fettled and I'm waiting on a replacement part now)

On Sunday it broke down with the same fault I had previously experienced initially. It went back into the Mariner Dealer on Tuesday. The mechanic wasn't particularly interested in hearing what I had done to fault find and said he would fix it.

I rang Tuesday lunchtime to see how much progress had been made and they hadn't started it yet. This morning they are supposed to have taken it for a test on the River but I've still not heard from them.

Would you pay for the additional work, refuse point blank or come to a compromise?


Regards


Chris

this is the age old problem of do you pay someone who knows what they are doing 1 hours work to fix something or someone else who does not have all the right equipment and not really knowing what they are doing 4 hours to trial and error a fix.

i would be looking for a compromise for sure, and that would be close to not paying for very much time over and above the work they previously did to supposedly fix the problem.

check with lee fairweather who did seariders for him with a very similar fault, give them the symptoms over the phone and they may be able to give an indication of possible causes etc

never hurts to get a few views on this type of thing
