[QUOTE="FuzzyGrub, post: 213481, member: 3438"] That has the same gear ratio as mine: 2.25 The only way that works out, is you are way over the 6Krpm max. At 6K, theoretical top speed is only 30mph. At 31mph you are going faster than the prop is spinning??? With a reasonable slip of 10%, says the engine must be turning 6800rpms. [url]https://go-fast.com/Prop_Slip_Calculator.htm[/url] [/QUOTE]
