Outboard Help

[Guest Kaptin Kod]

Hello,

 

Having a bit of trouble with a 60hp 2 stroke out board and wonder if anybody has an idea what the problem could be.

 

Stating up she runs a dream to the pontoon (500 yards) turn her off load boat and lucky to get 7 knots. run for about 1/2 mile and stop for locks and again on restarting she is fine again, fished for a few hours and again she ran fine yet after anchoring up for about 5 hours could not get any speed but you can feel now and again where she tries to build up and dies back down again. went back into the lock and switched her off and on restarting she flew.

 

Have cjanged plugs, fuel tried turning her off and restarting mid journey but nothing seems to help. Any ideas what I should be looking for?..

 

Thanks in advance

Not sure of your exact problem, does it reach it normal working speed from time to time, or does it only become sticky when you give it 1/2, 3/4, full throttle?

 

If if runs smoothly at low rev, i.e., little throttle, I would bet it's a fuel issue. Have you look for kink in the fuel line, or have you change the inline fuel filter lately.

dodgy fuel pump???

[Newboy]

One way to find out is fuel it with a spare fuel tank, if it runs then it's filter/blockage, if not it could be fuel pump or something else.

I'd go for fuel/air.

 

Have you checked that the air vent on the fuel tank is properly open and not gunged up with muck? It could be getting starved of air and causing a vacuum. When you turn the engine off the vacuum has time to release and allow air back into the tank. When you start she's initially ok, but as the vacuum builds again the engine is struggling to get fuel.

 

Worth a look.

Bob,

 

I would go with that. I had a similar experience ( except in my case I forgot to open the valve ! ). The fuel tank actually started collapsing as the fuel was sucked out leaving a vacumn.

Thanks for all the advice will check it out and report back, think I will change all hoses and fuel filter and see if it makes any difference.

Hi Kaptin kod

 

I hope you sort your engine problems pdq. and if not keep asking those questions.

 

Why not register in the forum, it costs you nothing to be a forum member and so long as you dont clear your cookies you would be signed in automatically each time you return.

 

Also makes our figures look good ie the more registered members the more popular we seem to be

 

Thanks

Done

[Newboy]

Which is done? Registration or the outboard?

 

If it's the outboard, what was wrong with it?

Finaly think I've found the problem, engine runs fine on initial startup, wait 5 mins and start running she dies off on revs and cuts out. Tried getting a mate to pump the primer bulb while running and shes came back to perfect running.

 

Will fit a new diaphragm into the fuel pump and hope it works.

Change/clean the fuel filter too.

Hi

 

I would also check the fuel lead and its connectors.

 

If you can borrow a spare it is an easy first check, and check the fuel tank vent is open

Hi have done that, seen the video and worn out the tee shirt and watched the tank shrink in size!

 

Best part is letting the air in again and seeing if it retains the original shape

Replaced pump diaphagm, filter, tested on drive and it seems ok, will put back into water and give her a good testing.

 

Thanks for Advice
