In forward gear the temp would reach 160 and then drop to 158 and sometimes go over 160. Idle under bridges it would go a little over 170. A...

    Attempted Sabatoge?

    What do you fellow boaters think of this: We pull up to a large usually active cove for a swim. There are a good many homes that ring this cove. We are anchored in the center(40 to 60 ft of water?). I am swimming and feel something hitting my side. Look down and just under the waterline is...

He cruised around like that for awhile and then the boat jumped out of the water and sat way above the water line. I have always wondered how these boats keep from...

    Used Doghouse?

    The previous owner was a Home builder and built a cedar doghouse for the i/o merc cruiser I now own.<br />The freakin thing is heavy! On the good side it does keep the sound down. I would say it weighs 40 to 50 lbs. I would think less weight would lead to a speedier boat etc. Anyway is it hard...

    Keil Covers

    I was thinking of buying a Keil(sp?) strip to go down from front to back of my 18ft boat. The ad says it protects the body of the boat when mooring it on the shoreline and docking. Just enough to cover the bottom part of the V and most of the way up the front. Lifetime warrenty comes with it...
