Trim tabs and turn fin height

[Brushless01]

Hi guys,

Today im going to install trim tabs and turn fins on my HOR Prince 25 and was wondering how high from the bottom of the transom should the tabs be mounted ? Also should the fins be mounted at the angle of the vee of the hull ?

Thanks

Mount the tabs around 1.5-2mm up from the hull bottom, Dont mount them level. Turn fins should be at 90 degress to the hull bottom, So looking at the transome of the boat straight on both fins are angled out whilst rudder is upright to give some idea as to what i mean by angled out. Looking from the side of the boat swivel them on the bolt to around 45 degrees as a starting point. Or simply look at pictures on this site of boats rear end shots, Its allways easier than explaining what you mean. Martin.

Martin, does the 1.5-2mm up from the hull bottom apply to all trim tabs on any boat?

I believe most fit tabs above hull bottom, You get less drag.
