My learn-to-DIY outboard is once again giving me problems!
I have had my 1999 90 hp Mariner for just about 6 months and have been slowly working through replacing all of the upper unit. I bought the boat cheap and will fix a problem, get her running for a week or two, then have a new problem to diagnose and fix. I can honestly say without sarcasm that I've enjoyed the project, but I'm definitely ready to have a bit more consistent use.
My latest problem was trouble engaging forward gear with the boat running which lead me to my shifter cable. After I adjusted, I ran the boat on muffs to make sure I had fixed the problem and everything went smoothly. However, after about fifteen seconds in neutral after cycling through forward and reverse, my engine started to bog down and eventually cut out. I tried restarting and couldn't get the engine to start until I gave some throttle in neutral before starting. This worked a couple times, but would end up cutting out each time. It then got to the point where I couldn't start at all and my primer bulb wouldn't harden. This being the last system I hadn't reworked, I trimmed all of my fuel lines ~ 1 inch, reattached new hose clamps, bought a new primer bulb. My bulb still wouldn't harden, so I bought a new gas tank to try and account for a loose seal on the brass attachment for the fuel line. Still nothing. Ive pumped with the bulb while vertical, attached and reattached each fuel line connector both from gas tank and engine, and can't seem to find my problem. Went back under the cowling and each time I pump the ball, I hear air being released from somewhere in the internal fuel lines. Is this my issue, or is this typical? Please help! It's tarpon season and each day I miss is a major issue in my life
