PHP Warning: Use of undefined constant VBA_SCRIPT - assumed 'VBA_SCRIPT' (this will throw an Error in a future version of PHP) in ..../includes/functions_navigation.php(802) : eval()'d code on line 1 Prop for 90hp vs 70 hp
I have 2 x 70hp 4 stroke Suzukis running a 15inch pitch OEM Suzuki prop. Im not unhappy with it.
If I upgrade the engines to 90hp Suzukis what size prop would you guess will be the right place to start?
Note the 70 and 90 hp engines have identical gearing.
