sporte77 posted a topic in Centurion Boat Accessories, Electronics and ModificationsI wanted to start a thread for Fi21 owners who have upgraded their stock prop. I've got a 2018 Fi21 with the PCM L96 (409) engine. My stock prop is the ACME 1235 (14.5x14.25). At sea level, I'm seeing about 4100-4300 RPM surfing w/ full ballast & about 10.5-11mph. Top speed is about 33-34 at 4900 RPM. Also, the holeshot is just fine. Anyone gone with a bigger prop to get the RPMs down? Please share your actual experience.
2012 Enzo - Ok - this just happened yesterday. The MPH and RPM indicators (analog) will pop up on start, then fall all the way to below zero and don't function. Also the Oil Pressure and Water Temp (I think this was the other gauge) on the display don't show any measurements (these are the two vertical "bar graphs" on the display). PLUS my ballast tanks won't fill... I've had my MPH gauge not function in past, but it was the large breaker just above the front battery, however this didn't resolve issue this time. I've checked the breakers under the helm as well as above the batteries - any other location these might be in? I did replace both batteries this past week, but the boat was working just fine since then (just one day). Any ideas??
Have a 2010 falcon v 353. It came with a 537 prop. I can only get 4900 rpm and 40mph. Our lake is at 2800 ft. Thinking of going to a 1433 prop as that is the one listed on the acme site for high elevation.. Anyone try this prop?
