i have just purchased two 90 hp two stroke Tohatsu outboards.
is fast displacement
(6ton) and max speed so for is 12 knots.
However I am only getting 4,500 rpm
max out of each motor
, when they should max out at 5,500rpm
The problem is that Tohatsu do not make a smaller pitch
prop than 11inch pitch
(props are 14 X 11)
What should I do,
One suggestion was to grind down the diamater from 14 to 13.75"???
