Changing Boat Motor/Gear Oil: Do It Yourself or Send it to the Shop?
Posted on 5/18/18 at 1:23 pm

Just curious to see how many of you do it yourself, and how many send it to the mechanic to do it?
I did my own yesterday for about $50. Didn't make too big of a mess . Except when removing that pump hose from the lower unit drain screw hole, had a bit of gear oil shoot out even though the top screw was in. I took that as "I probably shouldn't have added that last pump after tightening the top screw before removing the pump.
If my motor still runs after this weekend, I will probably continue to change my own, unless I'm already bringing it in for a different issue.
Whats the OB's preference?

I change mine. It’s just important that whoever does it that they know how. Adding from the wrong hole and you will damage your gears.

I followed the instructions on the manual, it was pretty step by step down to the ounces required for each, only they didn't mention changing the oil filter.

It’s best to let some anyways so you did no harm there. You don’t want it slap full.
I service all my own stuff, outboards included. Changing the water pump and a few other things on my small boat this evening.

I'm not sure if all motors have them but Yamaha's have a little "paper" washer for each of the two lower unit bolts that they recommend replacing with each change. At the least just make sure they didnt fall off unknowingly when you took the bolts out because they are important.

I think it’s just the opposite. A little is always going to leak in the time it takes to remove the pump and put the bottom screw in. That extra pump probably got you about right.

I've changed my own with no issues so far.

You are correct. I checked mine, however I did not replace them. I ran it for about 10 minutes with the muffs once I was done, to check for leaks anywhere, or for the oil light to come on, and all was good. I will pay close attention this weekend to make sure there is no seepage.

Good point.

You may see a little sheen when you first put her in the water just from oil that may still be on the outside of the motor...I would check once you get back to the dock on your first day if you see any sheen. But it sounds like you are in top of things, it was just my .02

Thanks, I will pay very close attention.

Done my own for 30 years.
Drain.
Fill from the bottom.
Put in the top screw (it will help keep it from draining when you unhook the pump or pull out the tube.
Put in the bottom screw.
If yours has washers / o rings that need replacing do so in the process.
20 mins to let it fully drain, less than 5 to refill.

Do mine. Just buy the maintenance kit. Includes the washers, water pumo, oil filter, anodes, plugs etc. I have a Suzuki. Pretty sure Yamaha has one also. That and a PDF service manual and you're good to go.

Where might i purchase said kit?
Posted on 5/18/18 at 4:24 pm to Homey the Clown
Amazon, or anywhere that sells / services your brand of motor.

Did mine today as well, pretty much do all my own maintenance work. Get a hand pump that had the threaded insert to screw into drain/fill hole on lower unit.

Yall hand tighten yall oil filter or use a tool? I used a tool this time. Prolly put it on too tight.
Posted on 5/18/18 at 5:19 pm to LEASTBAY
Anodes are probably the most overlooked maintenance item and are of extreme importance
Posted on 5/18/18 at 7:01 pm to Homey the Clown
My suzuki service manual says use a filter wrench to tighten filter. I notice the suzuki filter has an O-Ring type seal on it and one for a car usually has a flat type rubber gasket. Not sure if that is the reason they recommend a wrench to tighten. Heres where I usually order my suzuki kit.

Hand tighten and agree on anodes

Well my filter is tight as shite, put a few little crimp dents in the filter when installing. Just figured since i couldnt take the existing one off w my hands, the new one needed to be tight too. Then i read online most people tighten by hand only.
