Just got induction tach so WOT / pitch games can begin. May also try raising motor (want 40km just cause).
Here is a hint for induction tachs - before leave home take them apart and seal them properly... was non-functional for this attempt.
However, on the water boat + motor + 300 pounds passenger & gear saw 41.5 km/hr. Max speed on GPS once home shows 45km/hr but it may not have turned off before being put away thus could have picked up speed on way home. So this means just have to try again
Can say got a little bouncy above 40... good fun.
