FCS II H4 PC Carbon Tri Fin SetDie FCS II H4 Finne tritt die Nachfolge der lange vermissten H2 und H3 an. Waren die H2 Finnen noch ultraschnell aber nur schwer zu kontrollieren, haben sich die H3 mehr an traditionellen Finnen Shapes orientiert. Mit der H4 geht FCS jetzt einen neuen Weg, der irgendwo dazwischen liegt. Radikal ist das H4 Thrusterset schon alleine, weil die Seitenfinnen und die Center Finne komplett verschiedene Shapes haben.

Die FCS II H4 Finne tritt die Nachfolge der lange vermissten H2 und H3 an. Waren die H2 Finnen noch ultraschnell aber nur schwer zu kontrollieren, haben sich die H3 mehr an traditionellen Finnen Shapes orientiert. Mit der H4 geht FCS jetzt einen neuen Weg, der irgendwo dazwischen liegt.
Radikal ist das H4 Thrusterset schon alleine, weil die Seitenfinnen und die Center Finne komplett verschiedene Shapes haben. Die Idee dabei ist, dass die Seitenfinne maximalen Drive und Kontrolle für Railturns geben sollen, während die Mittelfinne auf Reduzierung der Reibung und maximalen Release optimiert ist. Dazu kommt noch ein dreidimensional optimierter Foil für minimalen Drag und maximale direkte Kraftübertragung plus Schweizer High Tech Produktion mit unidirektionalem Carbon.
In der Summe bietet das H4 Thrusterset eine gelungene Kombination aus Power, Drive und Hold. Wodurch es sich aber vor allem vom Surf Feeling traditioneller Finnen Shapes abhebt ist: Speed - mit Sicherheit wird das H4 Thruster Set die Geschwindigkeit Eures Surfens deutlich erhöhen.
Das FCS II Finnensystem kommt ohne Schrauben und Werkzeuge aus. Einfach die Finne vorne einstecken und hinten einklicken - fertig! Die Plugs sind gleichzeitig kompatibel mit dem klassischen FCS System, sodass alle "normalen" FCS und FCS-kompatible Two Tab Finnen eingesetzt werden können. Hierzu braucht man lediglich das FCS II Tab Infill Kit, das FCS Schrauben, Fin Key und Tabs zum Schließen der Lücke vor den Finnen beinhaltet.

Helped to improve combustion in 12 year old Mercruiser 3.0L engine
Color: Blue, Number of Items: 1
I used the whole bottle in 1/2 tank of questionable gasoline from used boat from dealership, with no idea what mixture of gas water and particulates was in the gas tank in this 12 year old boat. The dealer started up the boat, and it was taking a minute to get the idle going. He mentioned that the gas was a few months old, but I am guessing that is was more like 6 months old. This is the TKS engine, self priming. I think some water / condensate was in the tank. Before taking out to first trip, I added bottle and 5 gallons fresh gas. That trip to the lake, I still has some issues getting it to start easily. Ran OK, not great that day, went home, changed cap and rotor and wires. Next trip, 1 week later, the 3.0L started great, ran great, I am not sure if it took some hours to fully mix and interact with the old gas, neutralize the water, and perform it's reactions, before it made existing gas more combustible, but that is what it seemed like to me. ***UPDATE**** - I had strange fuel issues the next season after using this product. I had to replace the fuel pump and many other fuel delivery components including the carburetor. Not sure if this contributed to the fuel system failing, the long term effects outweigh the short term gains.
