Is FWC a significant advantage vs RWC? Seems to me it is...I remember
seeing the Chesapeake being sucked into my engine at low tide on the Elk River. Although this would happen to a heat exchanger in a FWC engine, the long term damage of corrosion, etc. seems much less. Is it worth making a decision regarding 2 comparable boats if 1 is FWC vs RWC? |

I would go for the FWC, and inspect or have someone inspect theheat exchanger and pipes very carefully. Some years ago, when I was looking at a center console boat with a an FWC inboard, I noticed it was equipped with a hose connection to flush the heat exchanger. I don't remember the details, but it wasn't very complicated. -- Whatever moral rules you have proposed, abide by them as they were laws, and as if you would be guilty of impiety by violating any of them, *unless* you are a conservative Republican office holder or minister. If that is your position in life, then anything goes. |

FWC is always a plus. The engine can be run at better operating temps, giving better fuel consumption numbers. RWC engines, in salt have to run below designed operation temps as salt will precipitate out at the higher temps. Plus lots less corrosion problems and easier to winterize. I do not drain my engine for cold weather, just check the antifreeze. |

Yes. Generally speaking. Also pay attention to everything about the boat. Look for signs of neglect or shoddy maintenance. If everything looks ship shape, chances are the running gear is well taken care of also. |

I don't remember the details, but it wasn't very complicated. That may have been MST, but they went Tango Uniform. Then, again....... maybe not. http://www.mstguardian.com/ Maybe. I didn't look close enough to pick up the details. The salesman pointed out the hose connection and said it was to fresh-water flush the heat exchanger. If memory serves, it was on a Shamrock boat. -- Whatever moral rules you have proposed, abide by them as they were laws, and as if you would be guilty of impiety by violating any of them, *unless* you are a conservative Republican office holder or minister.

RWC engines, in salt have to run below designed operation temps as salt will precipitate out at the higher temps. Plus lots less corrosion problems and easier to winterize. I do not drain my engine for cold weather, just check the antifreeze. To nitpick just a little: It isn't salt that precipitates out inside the cooling passages in the block. It's carbonates, notably calcium. And it isn't really antifreeze, its function in all cases is to raise the boiling point, while freezing is often not an issue. I just call it glycol. A trivia note: 90% glycol freezes at -90 F while the pure stuff freezes at 8 above. However it wouldn't matter if it did, it isn't water, and doesn't expand when it freezes. 50/50 will get you all the boiling point you need, while the pure stuff is a lofty 410. You can't get away with pure water in a modern car, you would boil it all out in no time. Coolant, not antifreeze. Not that it matters. You ask for antifreeze when you need some glycol to raise the boiling point. At one time they used methanol/water mix in the winter, and plain water in the summer, when all the alcohol would boil away. You used to have a 140 F thermostat for winter, 180 for summer. Casady |
