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.
