I finally was able to work on my Ryan, I wanted to go 4 stroke, settle on a Magnun XL 91, I used a Dave Brown mount 90FS-9004.
manufacture recomended a 5 ply for firewall. and I moved the firewall back 15/16". I ended up installing some of the front blocking on the bottom, out of step of the directions. was having trouble centering firewall. this made it easier for me. it should be dead center now.
I need to fasten gas tank, I am using 14 ounce DU-Bro manufacture says 12 or 14 ounce. not sure on how, I saw a thread that talk about fuel foaming, will use some foam around tank. and velcro. (any suggestions). need to run line for throttle, then I can close fuse[ up with sheeting. I I'm going to try to list pic's.
