The trim system with the hollow bolt were a pain, try to keep the silicone sealer out of them, and when they galled, good luck getting them out. We made a puller to jack them out with a slide hammer, because we changed engines all the time. We also used regular nuts so we would not stick them. The steering system was also not cool, as the tilt tube was over the top of the transom. When we needed dual cable steering, there was some engineering involved, which was not simple or effective. You needed dual cable because the engine had a LOT of steering torque because we started using the Alpha 1 gearcase, after a while we had to change the gearcase quite a lot. JFL
