O/B Question

[CaptMarc]

I have a 35' boat with twin diesel inboard, don't get gas inboards. To winterize my motors, I run 5 gallons of Freezeban through each engine and put a bottle of diesel stabilizer in each tank, thats it for the engines. I usually change my oil before I put it away for the winter, a mechanic told me if the oil has more than 25 hours of running time, it is good idea. During the summer, you have to check your stuffing boxes to make sure they are ok, change oil when you are suppose to. With a diesel, there is no ignition system, so it is only fuel and air to make it run. Newer engines are mostly electronically controlled, they are a different animal. Not sure the logistics of what problems they can run into, if any.
