Do you have to drill holes in your motor to mount it? That's the only thing that scares me away from using plates. Last thing I need is a hole gone bad in my motors lower unit.
Yes. You need to drill four 1/4" holes fastened with stainless steel bolts and lock nuts on the anti-cavitation plate. If it doesn't work out you can remove the unit and just leave the bolts in place. I've done it in the past with a hydrofoil that I didn't care for. I removed it and left the bolts on and had no negative effect on steering, performance, etc. I'll post this weekend on how it works out installation and performance wise.
