1997 mariner 60hp bogging down issues

[ruffneckwaterfowlers]

I have 1997 mariner 60 hp that when I idle around for a while and go to give it throttle it just want to bog down or die unless I pump the fuel ball while it is bogging down I cleaned carbs 3 times went over all fuel lines everything I could think of . Also the boat sat for 8 yrs without running and I also drained fuel tank and put 93 in it with fuel treatment and still does it. I'm running outta ideas

Have you tried the open the idle mixture screws another 1/2 turn out (CCW) trick? That's cured many a bog.

Rebuild the fuel pump as fuel pressure is low. The reason it bogs is carbs are not full and pumping bulb fills them and your bog ceases

I will have to try that I will let you guys know thanks alot

Pumping the bulb tends to cause minor flooding of the carbs--sort of like accelerator pump action--that can carry a too lean idle motor into a successful power up.

Now I seem to happen to have a hesitation rebuilt fuel pump n everything seems good now with the other problem
