    marine growth on outboards / outdrives?

    Since my motors are always sitting in the water, they always have lots of alge and other crud caked on them. Do you guys clean this stuff off or what? Does this stuff grow up inside the engine as well? I'm wondering if it'll choke off my water passages and burn up the engine. I aways get a healthy stream of water coming off both my outboards when they're running, but I still worry about this.

    I brush it off the outdrive on my runabout a couple times a year. The outdrives on my houseboat do not see the sunshine because they are tucked way under the swim platform, so I do not get any growth on them.

    My outboards can get caked with it. I'll probably start pressure washing them once a month during the boating season.

    I cleaned mine with muriatic acid. I tried lime away first but it didn't get it all off. Now that they're clean I'll use lime away this year.

    I also keep mine raised up during the summer when not being used.

    when i had houseboats with outboards i power washed them every month ,then to get them really clean i would spray them with tidy bowl and leave it sit about 5 minutes then power wash it off. it always came spotless clean.we even used it to clean the bottoms.

    All of the fishermen that like to cast under my houseboat are not safe for the fish either.

    Oh that irks me too EastTN. I'll be sitting on my front porch and hear one of those fisherman hit someones boat with their lure. I read them the riot act. I've requested the marina to hang signs about not fishing near docked boats, but they have yet to comply.

    Several years ago, my neighbor had to have his boat pulled one year because something was wrong with his lower unit. Upon inspection, they found a lure was stuck in it and had ripped the boot open allowing water to get in it. It was a $3.5K repair bill!
