Skippy J started the thought but I need to close in on the concern. This boat, these engines have never had an easy day. Next to impossible to idle around (Arneson drives can not drive a line at low speeds), when you find clear water, you have to open them up and run hard to keep on plane and make a straight line. So, just about every hour has been under a load. This is also going to make da wife mad. Real slow wallowing around or going fast and not see anything while burning fuel.
