9.9 Yamaha 4 stroke. I ran it for two hours today and when I pulled the boat out I noticed there was a small amount of motor oil running down the outside of the lower unit. Since the boat normally stays in the water I have never observed this before. Is this normal?
Any suggestions where to start. 9.9 Yamaha (2000). It runs great and never any problems until now. During my last sail I was pulling into marina/slip and running at idle speed as usual. The motor shuts down as if it ran out of gas. When I got it into slip I immediately cranked it back up...
2000 Yamaha 9.9 MLHY. It cranked fine when I left marina. I sailed for a while and tried to start motor to go in. The pull cord would not budge an inch. Completely locked up. Took the cover off and started it with a knotted rope on the fly wheel. When I got back the crank cord was working...
My outboard has a small screw on the lower section that unscrews and an adapter screws in that will attach to a hose for flushing. Where do I find the adapter? I have been to the parts suppliers on the internet and cannot find one listed.
Also, if I find one does the motor need to be running...
I am going to make a routine replacement of the impeller. Do I just need to buy an impeller or are there gaskets that I will also need to change? Do these all come in a kit?
I tried out sailboat with 9.9. I didn't read up on the motor until later. The motor ran fine but I don't remember the oil pressure light coming on. Can you see them in bright sunlight? Do they normally work? I understand that the motor will run rough if the oil pressure is too low...
I am buying a boat that has gate valves that I plan to replace with ball valves. Currently there is a thru hull with the gate valve screwed on. The valve is the type that does not screw all the way down to the inside hull.<br /><br />I have notices two types of ball valves. One has a flange...
I have a 9.9 long shaft (2001) on a sailboat and it is hard to reach the throttle andshifter from the helm. It is not electric start. I would like to add a control box. Do I just order the control box or do I also order cables, etc. and is this a do-it-yourself job?
I just bought a sail boat with a Yamaha 9.9 with the gear shift on the side of the motor. Supposedly it is a 2001 model. I saw another 9.9 Yahama today about the same vintage with the gear shift on the throttle. Can mine be converted? If so what needs to be ordered and what would it cost...
This is a Honda 8hp that I may be getting with a sailboat. It shifts into forward just fine but when shifting into reverse the gears grind or if you shift fast it will clunk. Is this a problem or normal.
I need to flush/clean out the cooling system on '81 Mariner 4hp 2 stroke, after changing impeller, to be sure there is no clogging or blockage. Other than a blast of compressed air or water what should I do?
My '81 Mariner 4hp 2 stroke pumps intermittently. When it quits pumping steam comes out. I shut it down and wait a few minutes then it pumps ok for a few minutes then steams again. I replaced the impeller last year and it has not be operated more than a dozen times with the new impeller. I...
I bought the motor three years ago and never thought enough cooling water pumped through it so I replaced the impeller. One of the blades was missing but it didn't pump any more with the new impeller. It is used very little on a sailboat and I haven't had any problems until this month. The...
