Troubleshooting & FAQ

How do I confirm this impeller fits my Bravo sterndrive?

This impeller fits Mercruiser Bravo models up to 1999 that use an engine-mounted sea water pump with a plastic housing. Please check your engine's year and pump housing type. You can also cross-reference your existing part number with the numbers listed in our Part Number Cross-Reference table.

What are the signs of a failing water pump impeller?

Common signs include engine overheating at idle or low speeds, a weak or no water stream from the tell-tale outlet, and visible cracks, stiffness, or missing blades on the impeller upon inspection.

How often should I replace my water pump impeller?

For preventative maintenance, we recommend inspecting the impeller annually and replacing it every 1-2 years or every 100-200 hours of operation, depending on usage conditions (e.g., saltwater vs. freshwater).

Works great as advertised
Style: Printer & Inks, Style: Printer & Inks
Working great so far! Enjoying starting doing sublimation work. A rookie a few weeks in and it's going well. Print quality is decent. Not having paper jam issues. Was easy to setup. I had to goto Epson and download a current print driver to get all the print properties and printer settings I needed. Was easy. After I installed the 2nd driver and saw it worked better, then I uninstalled the 1st epson driver. Helped allow for 8.5 x 14 page size and high quality. Just a few options needed that were not showing on the original print driver. Took me a few days to figure out what was going on. It helped with the quality of the prints after I got the better driver. So the end product is better also.

Prints great, wifi was an issue

Got the printer a week ago and have printed something every day so far and the quality of the prints have been fantastic. Arrived and set up without any major issues, other than not being able to connect to my local wifi. Had to get an Ethernet cable to connect to it.
