Fits my 1985 Evinrude (120hp) with yellow fitting… other fitting fits other enginesOnly thing I wished for was a swivel at the fitting … hard to unscrew from plug (I’ll deal with it .. as this is a bag for the Buck )And only change bottom end oil … a few times

Saw the you tube video on how to use it. Changed lower unit lube on my 9 HP 4 stroke Mercury outboard. Worked perfect, a few minutes and the job was done with no mess. Made exactly for the job and we'll worth the cost.

This is a perfect tool to help you change your two stroke engines lower unit oil.Each off season I winterize my engine and this is a quick and easy task to check off my off season maintenance list.I’ve used this tool for two seasons and there’s no reason why I can’t see it lasting for a few more.It’s definitely a job that can be done by a DIYer, rather than paying someone to do it.Check you engines specs and make sure you pick up two washers for the two bolts that need to be taken out to get the gear oil out of the lower unit. It’s a cheap insurance policy that you get a good seal when you tighten the bolts back up.Also, put the old gear oil in a plastic container for a day and see if there is any separation of the old oil...if you see a layer of water, then water has intruded into the lower unit- which is something you want to get fixed by a pro right away or yourself if you are comfortable enough with changing gaskets.This tool is a terrific help and needs to be part of your off season boat maintenance tool box.I hope this review was helpful.Happy and safe boating.

Absolute must have for any boater. If you change your lower unit lube regularly (which you should), this pump will save you alot of time and frustration. It is just plastic, probably cost about 10 cents to manufacture, but still the best $6 I've spent this year. It was SO nice to just screw in the pump to the lower unit and into the gear lube bottle and pump away. To be done correctly, it should be pumped in from the bottom drain hole. I have only used it once so far, and it performed as it should. No issues.

This unit fits the OMC drain thread on a Mercury perfectly. Another unit I have fits with only 1/2 thread engaged. Not desirable.No leaks. No mess. All plastic, yet works just fine. Takes only a few minutes to pump oil into the lower unit and the pump tubes spring return time is acceptable for this units price point. Thank-you, Shoreline Marine.

I have a 20hp Mercury outboard. I did not need the adapter that came with the kit but being a bit of a pack rat saved it in the back of the toolbox. This pump works great no leaks and it allows very precise delivery of the lube with little waste. I set the pump and quart of oil up so i could see the oil level in the bottle. Then I pumped oil into the lower unit until I was close to the 12 oz. capacity the owners manual listed. At this point I pumped slower until the oil just came out of the upper vent hole.I found this process more efficient that using a tube or squeeze bottle of gear oil.Best of luck.

Don't think about using one of those squeeze bottles to fill your lower unit - it will be a mess! Since lower units get filled from the bottom (drain) plug to avoid trapping air, it makes sense to buy this pump. The pump screws on to the threads of quart size necks that most oil manufactureres use. The threaded fitting at the end of the hose fits your lower unit, use the adapter if you have a Yamaha......NEVER USE A WRENCH - if it is the right thread, the fitting should screw in smoothly with just your fingers.Be sure and use the exact weight of GEAR OIL/LOWER UNIT LUBE that your manufacturer recommends. After draining all the oil old oil out, replace the washers that should be on the drain plugs. My Yamaha's bottom plug has a magnet built in to it so I can check for any metal filings. After all the old oil is out, attach the fitting from the pump on to the bottom drain. Your lower unit should be in the VERTICAL POSITION. Attach a new bottle of lubricant and pump away until you see the new oil start exiting the upper (vent) plug. At this point you'll want to install the drain plug into the upper vent drain and the unscrew the lubricant supply hose from the bottom drain plug. Because the vent plug is sealed when you take the hose out you won't lose too much new oil, but i still use my finger to seal it while I line up and install the lower drain plug. Make sure both plugs were placed with fresh washers/crush plugs and that they are tight. There, you are done!

I bought this item in preparation for winterizing my boat for the first time. There isn't much to this pump ... the body of the pump threads onto your gear lube bottle. The pump is connected to a length of clear vinyl tubing and on the other end of the tubing is a yellow fitting that threads into the DRAIN plug hole on your lower unit.It would be nice if the yellow fitting were able to twist as this would make it easier to thread into and out of the drain plug hole. As it is, the entire pump (and attached bottle) needs to turn as you thread it into your lower unit. This isn't a big deal, though it makes getting the whole assembly removed quickly to allow replacing the drain plug a bit of a balancing act. You'll understand what I mean the first time you use the pump, and it's not a problem. I have seen other, more expensive, pumps that have this feature.The pump did a perfectly fine job of pumping two quarts of 90W gear lube into the lower unit on my boat. However, before I was even halfway through the first quart bottle, the pump was leaking around the shaft of the pump. It didn't leak much, and it didn't seem to introduce air into the oil being pumped, so I didn't worry too much about it. However, it makes using the pump messier than it needs to be and definitely makes me question how many uses I'll get out of this pump before it's time to buy a new one.So, one star lost for the leaky pump and one star lost for the fact that the lower unit fitting doesn't swivel. Overall, though, a solid pump for very little money that will do what you need it to ... at least a couple of times.
