nautique engine woes

i had the same problem with my natique. it went on and on. i never really gave it much thought then it would run great and then not start. it turned out to be a carb problem. once my boat warmed up the gas would percolate over and flood the motor. easy fix. rebuild the carb

Finally ran the nautique on a separate fuel supply, bypassed the tank, line and filter, ran great, pulled the vent cover and then the pick-up tube, screen inserted in the pickup, was clean, checked the check valve and it was gummed up, will replace along with the fuel line and removed the screen, (has an inline screw-on filter) and will let you know how it runs....what do you want for 19 years old???

My 1979 ski nautique ran perfect last year. It has 1300 hours on it. Tried to start it yesterday. Will not start. It fires and then i get a brree noise any suggestions?

is the choke flap removed from the horn or free to flap in wind?

before you do anything, run the boat off a temporary fuel container and see how it operates after it gets up to temp. spin-on filters can be clogged with water even though they look clean.

if it runs well, you have found the problem and i would just take the tank out. an 86 would be due for a good cleaning. replace the tank to spin-on line if it is original, it should be delaminting internally by now.

repost if it is not fuel related.

Some electronic ignition kits use the balast resitor some don't it all depends on the resistance of the system.

But your problem sounds like the choke is staying on and you need to replace the choke stat on the side of the carb. Start the motor up and let it warm up, pull of the spark arrestor off and verify that the top butter-fly plate on the primary side (forward two)
is straight up and down, if it is not then the choke stat is bad OR you are not getting power to it.
