Hello all: This is my first post after some searching for the answer.<br /><br />I got my first boat last week. It's a 1975 Chrysler courier 154. It has a 75 HP engine. I took it out to the lake to have a look at it, and we had a little accident. It appears that I should have removed the motor lock before we put it in the water. It slipped out my hands and sunk to the bottom of the lake. I don't know what the real name for it is, and I need to know where to get another one. I tied the motor up so that I could trailor it back home. Can anyone shed some light on the subject please?<br /><br />Thanks in advance.
