Yam f-90 loosing prime

Runs good until anchored or docked for 30-45 mins. Then I have to pump bulb back up. Anybody experienced this?

Air leak somewhere. If you have a fuel water separator with a clear bowl, see if there are any bubbles in it. You might try replacing the fuel bulb first just because it is easy and it could be the problem. Get a yamaha bulb, not a sierra or tempo piece of crap.

what localdude except the sierra bulbs have proven to be reliable for us.
tempo, attwood, and moeller bulbs, however, are defiantely junk

I’ll try replacing bulb first. I don’t see any gas leaking anywhere, but I have always had strong gas smell inside console when first opened since it was new.

Could be as simple as the bulb.
