Modding os lower unit

[Jack Brady]

Hello, I was wondering if you guys are cutting the skeg on the os lower unit, I am talking about narrowing it. I have read something about this a while ago but cant find it. Also if you are cutting it do you cut it from the back,prop side or the front side and how much do you narrow it to? Thanks.

I don't change the shape of the skeg, but I do taper the trailing edge.

I only know of K&B lowers that are modded, not Os lowers...

There must be info on this on the forum.

Look at the link and Bill has cut the rear of the skeg which allows water to converge in front of the prop with hopefully less disturbance. Also steering takes less effort cut from the back.

pay close attention to what was said about kentley's skeg. he holds MANY world records B) . i also remember a full scale jet powered boat in australia going after the speed record. ken warby (sp) was the man's name, i think. he was quite a few mph short of it. he removed 1/4" of length/depth off his rudder, & promptly set a new record. trimming a skeg on the front or rear has advantages, no doubt, but it still presents the same frontal area to the water for drag. shortening it reduces drag...........
