When I bought my boat last year, older bass boat with a 1989 175hp merc, wasn't til a handful of outings I notice when pumping the bulb i a little gas spewed out under the cowling. Motor runs great, don't really have any issues but saw the very first fuel line coming in was coupled together or something. I got fuel line hose coming but my brother said if its running fine don't mess with it. It shouldn't be like this though.
