2005 115 hp Yamaha 4 sroke

[southwest]

I have 115 Yamaha 4 stroke motor, the primer ball will not hold prime, we have replaced the ball and checked hose to float bowl. Will build up pressure and hold ball solid till there. We then removed the hose off the fuel pump and did same process pumped ball but wouldnt hold pressure. Does anyone know what might be causing this? The motor will fire but pretty not stay running. Anyone know a good machanic in the Dent, Perham area that would come out to the lake, poonton is on lift. Thanks

So are you saying its running back down the hose to the tank? If so then the anti-siphon valve at the tank may be your cause.

Does it run ok? You just have to prime it each time?

I'd call Hoots Marine in Perham. All the work they have done for me is top notch. Don't know whethey they do "house calls" but you can ask. Good guys. Ask for Dennis.
