Hi! I am thinking about purchasing a 1986 tiller steer 18XD for running around our smaller lakes. Is this motor a lot heavier than a 9.9(1989). Are the motors reliable. I already have a 50 on the boat, but a lot of the local lakes were upped from a 9.9 limit to 20 hp.<br /><br />Thanks,<br /><br />Rick
