Tohatsu Outboards

Much more effective to pumo oil out than squeezing a 1/4 gear oil bottle specially with low oil levels, only con, hose should have a screwable end cap to seal unwanted oil spills...Read complete review

Higher horsepower Hondas need adaptor

The packaging states that adaoptor Model 8704756 is needed for Honda 2-50hp models; however, I found that my 130hp Honda BF130A also required the adaptor.

      This is the same product as name brand except cheaper and it works just as well. Don't waste money by buying the same thing for more $$. Just get this West Marine Brand and it works the same and will save a few bucks.

        Comments about Lower Unit Quart Pump & Lube Tube:

        Tried to use a pump without the lower unit screw and it was a messy disaster. This product has the screw in needed for a much less messy lower unit oil change, and not that expensive! A must have!

              Worked great for changing the lubricant in the lower unit of my outboard. Had to purchase an adaptor in order to use the pump on my Yamaha motor.

                    Comments about Lower Unit Quart Pump & Lube Tube:

                    I have several of these pumps so I can devote each type of fluid I'm transferring to a specific pump and avoid cross contamination. The last one I bought was to fill a rear differential on my vehicle. My others have worked great for outdrive lower units, etc.
