I decided to service my Mariner 9.9 last week and put a new water pump in the lower end and I just cant seem to get it to pump. It did some at first but then all I could get out of the discharge hole was exhaust. The guy at the repair shop quoted me a mere $180.00 Labor. I am in the wrong business!
Any thoughts?

1.) Yes, you're in the wrong business. Repairing boats can be unpleasant work, and it's very difficult to find and keep good help. A common scenario is a marine repair service hires someone with raw talent, maybe finances their tools, provides them with training, experience, and inevidably a potential client base whether the employer likes it or not. About the time the employer is starting to recoup their investment, the now experienced, competant, and reputable technician buys an old bread truck, paints "Mobile Marine Service - Cheapest Rates In Town" on the side, and goes into competition with their former employer.

Around here, it seems no matter how many people do this, there's never enough competant boat mechianics to go around. So, supply, demand, and all that, they can charge whatever they like!

2.) As for your water pump problem, you could try submerging the foot extra deep in the test tank to see of you have a marginal pumping problem, or not. Also, you could take the foot back off, and spin the drive shaft with a drill motor to test before reassembling. Possible causes include: marine growth or other blockage at or in the water intake, broken or missing impellor key, air/water leaks in the pump shell where the upper and lower portions join, leaking shaft seal, air/water leaks in the cold water tube from the foot to the powerhead (usually at the ends), clogged passages in the powerhead, stuck or clogged thermostat, plugged discharge orafice (either piddle indicator or internal at the exhaust mixer). You just have to study how it's supposed to work, and follow the water through the system to see where it's stopping.

Thanks Leon,
I took your systmatic approch and found out I had just messed with the whole thing so much (I dissesembled the lower end no less than 5 times) that I had cracked the new impeller. I found a new impeller and was on the water by noon. The winds were very light to not at all but this morning I am sporting my first sun burn of the season!

Thanks again for your help
