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.
THIS ADVERT HAS EXPIRED!
ACME 1235 prop. Used. Good condition. 14.5x14.25. 1-1/8” Left. Stock prop on all 409 engine Fi & Ri. Also stock in some Malibu VLX with 350 monsoon. Would make a good spare or cheaper than new replacement. Asking $400. May ship if you want to pay for shipping. Located in 98685. Vancouver/Portland area.

sporte77 posted a topic in Centurion Boat Accessories, Electronics and ModificationsJust got the Fi21 yesterday. I got the optional PNP transom bag with it. I found that I don't need it. When I was using the quicksurf profile settings (surf left, etc.) - I had the transom bag set to zero - but it kept filling anyway! So my question is this - I am going to remove the transom bag. Can I somehow deactivate the pump through programming - or do I have to unplug wiring? Or, do I just attach/join the fill and overflow hoses? Obviously, if it's set to zero & keeps trying to fill anyway, it's going to pump water in the transom locker. There is one other BIG DEAL I am worried about with the Fi boats: Centurion has not come up with a "recall" style dealer fix for the fact that if you sit with the engine shut off, while full of ballast, water is going to go up the exhaust into the engine. That's a pretty big deal to me. I don't think I'll forget - but how many engines have gotten - or will get water inside the oil. Sure, after a hydro-lock, the dealer will drain the oil and get out some water - but it will never get it all out. It's definitely going to reduce engine internal component life. Factory guys - are you listening?
I have a garage door opening of 7'10" (8 foot door). While shopping for boats last year (I wanted an Ri217 then) - I found that NOTHING fit. My 2012 Malibu VLX's board rack on the tower actually touches the rubber seal on the top of my door now as it passes under. I've since taken some drywall off the area above my garage door that covers the beam. I found that the framing was done so that you could accommodate a close to a 9' door if you wanted to when the house was built. My builder installed 8' doors. It's tight - but for $1700 I found a garage door company that will add a panel & one of those low clearance jackshaft openers & hardware to bring my clearance up to 8'9" (limited by the structural beam". After I found this out - I decided to measure the Fi21 thoroughly to make sure it will fit - both in height and length. I park the boat in the DOUBLE side. I have a single 8x8 door and a double 16x8 door now. The trailers (and now boats) won't fit through the single door (they're wider than 8'). Here are the measurements I took of the Centurion Fi21 for garage fit purposes... Height will vary depending on trailer wheel size, hitch height, trailer brand. My dealer, Northwest Boat Sports, has lowered trailers before & said they have some "quick release" knobs for the bimini. Their not really quick release - but they are faster than the bolts that come stock. 8'3" - Tower Height when folded - measured on the tower frame itself. 15" wheels. Add about an inch for 18" - but you can lower the Extreme trailers an inch or so (don't know about boatmate). Note: The bimini frame sticks up above the tower higher than the 8'3". You can get some knobs that will allow the bimini to be removed. I measured the height of it - but forgot to write it down. 23'0" - Length with trailer tongue folded - to silent stinger (Swim Platform removed/Extreme brand trailer). 24'0" - Length with trailer tongue folded - to swim platform. 8'6" - Width of trailer tires. Outside to outside of tire. I'll have 1" of clearance with the platform off. My garage is 23'11" door to wall. If I cut out the drywall behind the platform & notch the bottom frame on the garage door I don't have to take off the platform - woohoo.... My VLX has one inch right now of clearance with the platform on. Since the Fi21 model is relatively new (about a year at this point) - I'll try to post as many mods and info as I can after I get mine in mid-july. Anyone know how to get to the impeller? That engine - sunk way down low makes me nervous for do it yourself maint. I've always done my own - but these deep hulls are quite a challenge to reach stuff.
