Awesome day out yesterday. Speeds were well up.
Not sure then what was the issue before but with the same set-up as before we were back to 16kts+
Then did some runs to test various.
Timmed right in (hole 1) 16.2 kts
hole 2 16.3 kts
hole3 16.8 kts
Then with 18mm wooden raiser under engine:
hole 1 16.5 kts
hole 2 16.8 kts
hole 3 17.2 kts*
*briefly hit 17.8 as absolute max recorded.
Not bad for a little 3.4m rubber boat and 9.8 horses.
It drove best on hole 2 with as usual some weight in the front (Pelicase with gear and anchor).
But with the wooden raiser the set-up was so much better, quicker take off, splashing eliminated but still no cavitations or issues in sharp turns.
Loco - where's that post/pic you posted of water flow over the cav plate etc - I am sure mine was just as it should be but cannot find the pic now to compare?
