Boat engine keeps dying, why?

Question

I have an Evinrude 60hp 3 cylinder outboard motor, it starts and and runs ok, but when i go to full throttle, after about 3/5 minutes it just dies. What could be causing this?

Answer 1

fuel filter???

how long has it been since you last ran it? if its an old two cycle then the carburetors may be varnished from the oil gas mix...

Answer 2

Could be a number of things, but it sounds fuel-related rather than mechanical. Fuel line problem or dirty gas. Have it checked.

Answer 3

It's starving for fuel, open the vent on your fuel tank. If its the original fuel tank it will not have a manual vent so it may be a bad fuel cap. Crack the cap when this occurs and see if it picks up speed again. If the venting is ok look for a pinched fuel line or other fuel flow issues.

Answer 4

if the engine has oil injection, get it taken off, my evinrude has been great since, i have also switch to synthetic oil, first was shell and my neighbour told me not to use that junk, he was right, i bought Lucas synthetic oil and my gas consumtion has increased by 75%, it's like a brand new engine,  you also may have problems with the coil pack, Ken.

Answer 5

Check your gas filter or for a vacuum leak in a hose sounds like you are not getting enough gas at high speed load.

Answer 6

Change the gas filter.....

Answer 7

Check your fuel take vent. Sounds like your not getting air in tank and after a few minuets of running the tank forms a vacuum and fuel flow stops.

Answer 8

take to mechanics shop

Answer 9

It needs work. Take it to a mechanic who is qualified to work on boat motors and have him diagnose the specific problem and give you an estimate of the repair cost. It may just be a clogged filter, or it could be that an entire clan of swamp monsters has taken up residense inside your carburator.

Answer 10

i used to have that problem a couple weeks ago ang it was the fuel pump, your problems sounds fuel related

Answer 11

sounds like a gas problem

I have a 70hp same make that had the same problem.

if you have a pump bulb inline try pumping it next time the boat starts to die, if it comes back then your having a gas flow problem.

Could be a number of things,

gas line getting air, pump bulb and or connector

gas filter (clogged)

fuel pump (bad)

anti-siphon pick up (bad)

Good luck, it took me a while to diagnose and repair mine, I ended up replacing everything but the anti-siphon pick up

Answer 12

you mite need to get a NEW engine
