    Vibration because of long exhaust pipes ?

    I have made my own thru-hull exhaust. It has been re-designed a few times. The way it is now, is silent outside the boat, at low speed. So I don't annoy any fellow boaters, when warming up the engine(4.3 V6) and leaving the dock. But inside the boat, is sounds like someone is holding a grinder...

    165 hp Stringer, dies when warm

    My friend has a 25 feet boat with twin OMC 165 electric stringers. I take it for a spin now and then. I never go beyond 1500 rpm, since it's not my boat. (I don't take any chances with this fragile old setup). We clean the thermostats now and then, since a small piece of rust hinders the...
