Seafury surface piercing drive setup

[ralphfdill]

Anyone here got in-depth knowledge about the fine tuning and setup of Seafury drives? Would like to know how sensative the system is to hull shape, exhaust line diameter, installation angle and more...

We could help as we know that product well.
What size SF drive do you have ?
What is the hull ?

Hello Hydro,

The vessel is a 42 ft hydofoil supported catamaran. If I have it right, the model drive is the SF 26. We beleive the props may be a touch too high.... Any idea how critical the 8 degree angle is?

Hope you can help.

The angle is not the most important issue.
Propeller hight or emersion is more important.
Hull shape and speed will effect this.
every boat will have a different requirment.
