basis method for pulp chips and fuel, where it is used for a one-time point estimate of what fraction of the whole is usable fiber (or fuel) and what fraction is wa-ter. As you will note, in the example provided above, the OD basis moisture content can (and will) exceed 100% on occasion â this is NOT an error â it simply re-
Shapers spin slower than routers, usually in the 7-14,000 rpm area and their power demand starts where routers leave off, (around 3 HP). Router tables are welter weights by comparison. It takes two routers to equal one shaper.
Check the ownerâs manual, the manufacturerâs website, or a dealer can look it up for you. The WOT rpm range is determined by the outboard manufacturer, and is where you want to motor to be under full throttle and optimal trim. A 2.6-liter Evinrude E-TEC, for example, has a WOT range of 4850 to 5850 rpm. For older two-stroke motors the WOT range is typically 4500 to 5500 rpm. On newer four-strokes and direct-injected two-strokes, the range is often at higher rpm and is narrower, 800 to 600 rpm rather than 1000 rpm. Ideally, youâll prop for an rpm right in the middle to upper part of that range.
