One thing I had not thought about with the engine conversion, was the steering, guages, shifter, and electrical. This slowed me down while I did research on the electrical for the Yamaha system. Also, the original dash board had so many holes that I had to figure on some way of mounting all my guages that I wanted, and still make it look decent. White plexiglass answered the call. I cut out all the offending fiberglass from the dash board and fitted white plexiglass to the top half. I arranged the guages and water-tight switches, then had to figure out how to make it water-tight. I used 3M 4200 sealant. I placed a bead all around on the original fiberglass; placed a piece of waxed paper over the entire dash area, then placed the plexiglass on top, and gently screwed it down, squeezing out the excess 4200. I allowed this to cure for 3 days, then removed the plexiglass, trimmed the edges, and low and behold, a custom fit, water tight gasket for the dashboard.
The hydraulic steering was another problem. The helm pump sticks out about 6 inches, which now placed the steering wheel in interference with my new Yamaha throttle and shift lever. I wanted to recess the helm pump into the dashboard. I built a woooden brace to mount the pump to about 4 inches into the dash board. This wood was sealed with West epoxy, then screwed into place. The helm pump now only sticks out about 2 inches, thus giving me the shifter clearance needed. Once the pump was installed, I cut another piece of plexiglass to fit over the helm pump and cover all the offending holes. I could now locate the ignition switch and begin all wire runs.
