Hi everybody.Welp ever since i have my boat ive always had problems with my primer bulb,i have to prime this motor everytime i went to start it evan if i was just sitting there fishing for only 5 minutes i would have to prime it to start it.Well today i took the cover off of the motor and while priming the motor i noticed that there was gas coming out of the botton carb hose where it hooks in to the nipple on the bottom of carb.Could this be the reason that i always have to prime the bulb to start and could this be what makes my engine bog out and die when i hit the throttle(runs fine at no wake speed).thanks guys
 
It does account for the slack bubble.
Obviously, need to first fix the leak and go from there.
It's possible the fuel pump couldn't keep up trying to fill the carb bowls due to the leak and compounded by the engine fuel demands at higher rpms.

Lets hope it is that simple.
 
As it relates to the primer bulb and the need to prime it before starting, you might want to check your fuel tank ANTI SYPHON valve to see if you have one and that it's working properly.
 
One thing too is i've always used the "hose" style zip ties for marine fuel hookups.. They are easy to remove, they hold an even pressure all the way around the fuel line, and they do not dig into the rubber like the metal ones do.. Maybe pick you up a bundle of those when you do the repair.

I agree with Bruce on the nylon ties. Three things make the job really simple. One, buy only quality nylon ties. (T&B are my favorites) Two, buy a tie tightener. (Either one is less than $15 at Harbor Freight. I like the red one better, but the blue one is great for tight spaces) Three, buy a wire stripper. The sharp cutters at the tip of the stripper make removing the ties a snap without nicking or cutting the hose.

Spanishmac, my thinking is that at idle and no wake speed the engine gets enough fuel to run smoothly, but as soon as you nail the throttle the extra vacuum from the engine starts pulling air into the carb at the leak, causing the engine to bog. The leak will also cause you to lose prime while sitting, again due to air entering the fuel delivery system. I might not be 100% on this, but it sounds logical to me. Fix the leak and I'll be willing to bet you fix the problem. At the very least you will be 1000% safer from fire than having raw fuel squirting around inside your engine cowling. :head:

:sly:Yeahp u r right destroyer the leak did cause the engine to loose prime,went outside this morning and the bulb was still firm(well not dead empty anyway) as far as running I still have to put a hitch on my blazer s-10 to find out if I fixed it.
