FABULOUS!

Installing a late model 90 hp Evinrude ETEC outboard on my restored 1964 Evinrude Sweet 16 boat gave it great power - but added a lot of weight to the stern. This, combined with the rear mounted fuel cell and battery, caused the boat to "porpoise" whenever I trimmed the outboard anything more than full down. The power was there to go faster, but the propensity to "porpoise" wouldn't allow it.
The Hydro-Shield changed that! As advertised, "Sweet Thang" planes quicker, corners crisper, and, as promised, has a 25% increase in top speed! Money well spent - thank you!
