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.

        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.
