Re: Speed of a Force 120
Bouyr20,<br /><br />There are 4 basic things that impact performance.<br />If one is off, it will impact the other 3...<br /><br />1. When you mount the engine, make sure the antiventilation plate is flush with the bottom of the hull. Too high and you will suck air and have a "blowout", too low and you'll create excessive drag.<br /><br />2. Next, when you take her out, trim the engine up as high as it will go without causing the boat to "porpoise" and pound. Trimmed too low and you will not get the proper angle for maximum efficiency.<br /><br />3. Make sure when its wide open, you are getting the engine into the proper WOT RPM range. (the range is usually stamped on the ID plate on the engine. If not, just ask on the force forum and someone will tell you) Too High and you could over-rev the engine, too low and you will lug it and cause carbon buildup eventually damaging the cylinders. The RPM is controlled by the prop pitch at WOT.<br /><br />4. Make sure the boat is loaded evenly so the weight distribution is equal front and rear. Too much weight in the rear and it will take a long time to plane. too much in the front and the boat will plow and have terrible bow steer.<br /><br />These 4 things will give you the max performance out of the engine. Try these out and let us know the results. There are fixes for each area if one is off
