Not sure if this helps but I have a 5.2m aluminium C/C with a standard 90 Merc 2 strk (new 23 hrs) that does about 36 knts @ 5600 rpm. :-/

My Haines Hunter 510 Breeze with 90hp Johnson 4 stroke gets 30.5 knots (or 56 klmph) @ 5600rpm with 4 people and normal gear plus 120ltr fuel.

Hi John,

I'm running the 115 Opti on a 5.4m Cyclone (Glass) for about 39 knots with 70l fuel and light load.

So your running a bigger/Heavier Boat ?, with more weight on board ? and a smaller motor. 32 knots sounds about right :-/
Whats the max Horse Power for your Sea-Jay ?

Cheers
Craigie.

hi craigie, it's only rated to a 90,they say the boat weighs 550kg what prop are you running on the cyclon.

cheers john.

John,

The Cyclone is running a 3 blade "Vengance" (spelt wrong for sure :P), not sure of the pitch etc, but will have a look for you. Was told the boat weighs 450 kg's approx.

Regards
Craig.
