Engines dont like to be idle, even for three or four months over the winter. And lets face it, all of us boat enthusiasts would rather be on the water than watching our investment sit quietly in the garage. Unfortunately, since this is Indiana, a majority of us must pull the boat out of the water by the end of October or early November if youre a risk taker!
Generally, engine blocks that freeze and crack are not covered by a boats insurance policy, so its important to take the steps to winterize your boat adequately.
Unless it is winterized properly, moisture, acids and corrosion will continue unabated. Winterizing the engine is one job that is truly critical. A small investment now can save you thousands of dollars later.
HAVE YOU CHANGED YOUR WATER PUMP IMPELLER LATELY?
According to Just Add Water Boats in Indianapolis, one of the most overlooked items during winterization is replacing the water impeller on your engine. The manufacturers recommend that you replace them every 2-3 years. The water impeller draws outside water to cool your engine. Unfortunately damage caused by a worn impeller can be quite extensive. It will usually cause the engine to overheat which can lead to problems with the cylinder valves, pistons, and even crack the block, leading to a large repair bill. These repairs are generally not covered by warranties or service contract.
The average cost to replace the impeller is around $250.00 versus a repair cost of $4000 - $5000 or more. If you havent ever changed your impeller or are not sure when it was replaced last, it is probably time. The easiest time to change it is during winterization, so you may want to consider changing the impeller this year.
