    trim switch-mercruiser alpha 1

    I noticed that the up trim doesn't seem to work. It will move up by using the "trailor" switch so I know that the trim drive is working. The down mode works OK. Could cleaning the switch fix it or is there something simple I missed?

    Fuel-Water Separater

    A really dumb question-but-when I winterized my Mercruiser 3.0 this fall, I didn't do anything to the separater. Am I in deep trouble? I followed the rest of the procedure OK but probably won't know for sure until spring.

    starter won,t engage sometimes. I thought the trouble was in the ignition switch but jumpering it was no help. Battery good. thought I heard a whirring sound when trying to start. Could it be a loose wire? (I hope)

    A suggestion about the missing plug

    To help prevent me from forgetting to put the plug in before launch-I made a plastic tag in red and wired it to the bow hook. It is the last thing you remove before launching. It just has the word PLUG ?? on it. As forgetful as I am it has worked well so far.

    Running in salt water

    I often hear about salt water being hard on boats. I have an 18' bowrider I/O that I enjoy running in salt water a lot more than fresh water. I am careful to flush the engine when we get back and hose the boat down with fresh water. Is salt water hard on the boat?

    bent prop

    I managed to hit something in shallow water and bent the prop- a small bend of about an inch. It is an aluminum prop. Can I straighten this myself or should it be sent off for rebuild? I haven't noticed any vibration.
