The project is a 1980 sleekcraft junior executive tunnel hull. Now the question is how to install these motor mounts? Can we use lags and resin? Also how do you install a rail kit in a tunnel hull do you have to through bolt the rail or can you lag it because if you through bol them it will have to go through the hull? Any suggestion or advice or pictures would be helpfull this is my buddies boat and i will be helping him build this boat its his first jet boat so we will be asking for a lot of advice and posting pics of the build.
