:welcome: sapper28id to iboats. Great to have you aboard...
I have to say that I don't think you will find an actual manual for your tri-hull boat. Most boat manufacturers actually didn't make manuals for their boats. So if you manage to locate the brochure, that would be probably all there is... Now engines are a different issue... However, post some picture and we can help you out with whatever your issues may be. JMHO!
