Customer ReviewsWrite a review
I have a 25' power cruiser which is a full Deep Vee fore and aft. On plane it tracks fine but at no-wake speeds it wanders 20 degrees or more when using my Honda 9.9. I recently bought the Dolphin Fin with the clamp-on kit and was amazed at the difference. On a recent 25 mile trip on the lower Columbia River, I enjoyed a comfortable cruise down stream with an ebb tide. Cruising was now a breeze making it a pleasure to use the out-drive as my rudder. This allowed a speed of 7+ mph at 1 gph, as opposed to using the 350 V-8, at 14 gph. And best of all, tracking was no longer an annoying issue! Now that this invention exceeded my expectations, I painted it silver to match my Honda as it will definitely remain mounted and ready to enjoy anytime I desire to slow bell for whatever reason. BRAVO-ZULU Uncle Mike, and Thank YOU!
BTW, I ordered it directly via phone and it arrived at my home in just 2 days time...
