Quality product and great value but marginal fit on my motor
by James from Huntington, West Virginia on October 19, 2015
Ordered this for a 2004 Mercury 9.9 4-stroke. The quality of construction is good and delivery was fast. Had difficult time lining up and attaching to cavitation plate. The bolt holes are just a little too wide for the Mercury and setting the tail further back leaves a gap at the rear of the notch. It took some modification to make it fit. However, once installed it performed as expected on a limited horsepower motor. But one does what one has to do to fish on 10hp max lakes. The product would rate a 5 if it were not stated it fit all outboards.
