I dont know that I like my boat anymore!!!!

[LandyAndy]

Hi Guys
What should have been a great spell away in Albany wasnt to be
Got down here last saturday and wasnt able to put the boat in the water until tuesday.We caught no fish and had to battle a heavy chop to get back to the ramp.
Next day was perfect boating weather.Graz and I were at the ramp by 6am,a very quick blast across King George sound and we were at our first drop,out past Bald head(past Whale World etc).After half an hour of drifting only a few small flathead plus a dirty big Nor West Blowie.
Decided to head across to Breaksea Island,spent an hour there,only raising rubbish fish and undersize reef fish.Then over the Michealmus Island,then Michealmus Reef for the same result.
It was a good time had,the wind was rising so time to head for home before the chop gets up too high.Happly heading in at WOT and the dreaded starving for fuel raised its head once again.The boat has done this almost every time Ive used it,normally its a matter of priming the bulb and away you go.This time it didnt go far and it stopped again,and again and again.We suspected the new prime bulb was faulty at first,so I re-fitted the old one.Got another 4 mins at WOT and it stopped again.The buld was sucked in which indicates the lift pump on the motor was OK.Graz had to keep helping keep the fuel up to the motor by pumping the primer bulb,anything over 2000rpm and he couldnt keep up.
We ruled out blocked breathers by opening the fuel filler several times.Eventually we got back to the ramp.
Last easter this issue didnt rear its ugly head,I had fitted new fuel lines,breather lines,fuel filter with water seperator,new primer bulb.I thought I had finally fixed the problem.Before coming down here I had a full service done,including getting kits put thru the lift pump and carbys.The mechanic said there were traces of water in the carbys so I drained the tank.
Once I get home the plan is to remove the fuel guge sender and see whats in there,then drain it again and remove it to clean it if need be.

The new Lowrance gear has a glitch,it freezes up showing no depth,then only 0.8m deep,despite being in 50m of water.It was showing on both the Sonar and side scan transducers so I suspect its in the head unit.After several re-starts it did work.

Any thoughts on the fuel issue that I may have overlooked,please yell out.Just missed out on a couple of days of perfect fishing conditions because I was over the boat

I am happy to fix your problem by taking the boat away and stopping you having to fix it.

Andy, what size filter are you running? You may be drawing more fuel than the filter can flow...

[Mick_Marsh]

Hey Andy, I'll swap you the boat for the Commodore.

[LandyAndy]

Andy, what size filter are you running? You may be drawing more fuel than the filter can flow...

Its only a 75hp motor,the filter is about 3" deep and dia with the water catcher underneath.I will double check part numbers to make sure its OK.

Just working on your observations that fuel primer is sucking in...

Would suggest lack of fuel:
So these are where I would be looking.

Fuel line from filter to bulb too small
Fuel filter too small or too low a flow rating.
Fuel line from tank too small or delaminating / collapsing
Fuel tap (if there is one fitted) is not opening fully
Fuel pick up in tank may have a filter (gauze) on it in the tank and may be blocked or restricted.
Fuel pick up has moved and is sucking to bottom of tank.

Do you run external tanks or in hull?
Can you borrow an external tank for a test? Plug straight to motor and bypass your fuel system to the engine...

Andrew are you able to use all the fuel. ? You said you removed the filler cap and that's why you don't believe it's a breather problem.

The pump on the hose getting sucked in is a fuel issue either not venting or not enough fuel flow.y point is , is the filler in the same part of the tank the fuel draws from? Otherwise try bypassing the fuel filter for a short fang and see if it happens then, you may have the wrong flow filter.

Assuming they test run the engine at service only difference is your fuel system. Take the hose off the filter and stick it in a jerry can, go for a fang and see what happens.
