When To Check Your Water Pump on your Bradenton Boat
Waiting to check that your Bradenton boat is up to date on maintenance may mean that you are actually too late. It seems the water pump on his 30-year-old Universal diesel had a bearing failure. What happens when this occurs is that the impeller inside the pump housing begins to scrape on the inside of the pump housing and, depending upon the design, maybe even the front of your engine block.
When you are looking at your Bradenton boat and see “black fairy dust” all over the front of your engine, it may be due to the fact that it is being caused by alternator pulley alignment due to missing shims on the alternator mount. The fairy dust is actually the fan belt on your engine slowly grinding away due to the misalignment situation. It’s powered rubber. This particular observation about your Bradenton boat might not always be caused by alternator misalignment. And that is right! It could also be water pump pulley misalignment. The bottom line here is that this sort of failure can really spoil an otherwise great cruise if it happens when you are far from home.
You should grab this pulley and see if it rocks from side to side at all, checking for any radial run-out in the bearing. You may also want to remove the belt temporarily and give the pulley a few spins so you can feel for any roughness in the bearing. Better to find these things out earlier rather than later. If you do feel roughness, or there is a lot of radial run-out of the pulley, you should order a new water pump as soon as possible. That way, you’ll be ready when it does fail. If you are already seeing the fairy dust, get some new belts, too. Pro tip: Don’t try to cheap out here. It is not cost effective to try and rebuild these pumps.
