Timing light is not used for adjusting points. Feeler gauge is the only tool needed to adjust points. Clean them up good with emery board or fine sandpaper and set the gap. Not rocket science. A timing light is used to make sure the points are opening "firing" at the optimal point in the...

To take care of the water leak, you probably need to replace your cylinder head covers. Not the head gaskets, just the cylinder head covers.

Spray it with a little WD40 and once you use it a few times, wipe that off and put marine grease on it. Happens to me every first time out in the late spring/early summer.

Your arms aren't long enough to turn the key and tap starter with a hammer? Maybe you need a hammer with a longer handle!! I'm just kidding you, but the hammer trick is a sure fire starter tester! At 15 years old, I got a job at a great little neighborhood gas station. The first freeze...

Older motors had a tiller handle that had gears and linkages. Newer motors have cables that go from the tiller handle to the linkages on the other side of the motor. We'll need to know as much as you can tell us about the motor (as mentioned above) I recently purchased a newer 9.9 mercury...

going from 19 to 21 pitch should reduce RPM's by 200-300. With that motor's potential, you may need to go to a 4 blade or a larger diameter if the drive allows for it. Sounds like you've got a monster of a motor on your hands! I've recently gone back to aluminum props. They are lighter and...

"adjustment is #1 phillips and needle nose pliers" is a bit confusing.

That is an incredibly clean 1969 motor. Looks barely used. If you had the backfire after all the work was done, I'd check to see if the flywheel key is broken. Take out the #1 spark plug. It's the one that's closest to the top of the motor. I don't remember which side it's on. Stick a...

I've always had one that is slanted to the back. That's just what's been on every boat I've ever owned. If I replaced it, I just went with what was there. Also, on occasion (4th of July), I'll stick a flag pole in there and the backwards rake works great for that too.

The small gear is your starter, the large gear is your flywheel. You've either got low voltage going to the starter or the starter is just bad. If the small gear is popping up every time, then the starter itself is most likely bad. Here's the real test of a bad starter. Yes, I'm absolutely...

I'm not very familiar with A/C systems in boats, but do you have some type of breaker box? If so, the buss bar should be in the breaker box where all of the white wires are connected.

Link and sync and timing is all spot-on. As far as the enrichment screws go, it depends on what manual you look at. Yamaha says 5/8 to 1-1/2 turns out. Others say 1 - 3 turns out and if you need more than that you need to replace jets. When I bought the boat, the previous owner had just...

search for Marine Stereo Cover on Amazon. There's just under a thousand of them there. This year, after having stereos in my boat that never lasted too long, I bought the Pyle bluetooth speakers on Amazon and use my radio app on my phone and/or music I have downloaded on my phone. Works great...

The Yamaha carburetors on my motor have idle enrichment screws. They allow more fuel to flow to the carbs at lower RPM's. I've got them turned out 1-1/2 turns which makes it crank right up even when cold. This is a great feature and it makes the boat able to idle through now wake zones with...

Sounds like your tilt/trim is wired to only work with the key in the "ON" position. Have you tried using it with the key on, but motor not running? That's annoying when getting ready to trailer or launch the boat. Is this a new problem, or has it always been that way?

I had a 15 HP Evinrude that I went to a few boat yards and got permission to look around at all the broken down (not worth repairing) boats until I found a similar year model 9.9 and bought the cowling for it. The cowlings were exactly the same size/shape and it fit perfectly. If you get a 20...

Just rebuilt carbs and replaced plugs and water pump all a couple of months ago. My routine for getting it ready for summer island hopping and just getting out and enjoying God's amazing creation on the weekends. Anyway, what I have is a slight annoyance and not really a problem. I have two...

What are you using to check speed? It looks a lot faster than than 22 MPH to me. But if you're using a GPS, that would be pretty accurate. With a little digging it seems that the third prop has a pitch of 9. If so, that would get your RPM's up, but top end speed might suffer. Obviously, you...

When cleaning the carbs, did you run a piece of wire or a jet tool through all the jets? Did you set the float levels like they are supposed to be? Was the motor working properly before you took it all apart, or what was the reason for all this work to be done?
