    4/3 blade bravo props

    Rpms are the same from 3/4 to full throttle

    I'm sure they are. Not paying $1000 for props right now though.

    How long should I allow my boat to reach it's true WOT RPM? A minute or 2, a mile? Previously when I was out the boat was only reaching 4300rpm, with a lot of throttle left. Should I be giving it longer time or distance to reach it's true wot? I just want to make sure my top speed and rpms are accurate before I go changing props.

    I found these on craigslist for $400. Props are dirty but straight. Obviously I wouldn't be able to try them out before buying.

    The blades I'm looking at are mercruiser. I should have mentioned that.

    So regardless of the rear blade being a 4, I should still expect the same increase in rpms even if it was a 3 blade.

    Most efficient rpm...

    Totally get that. OP was asking for his most efficient cruising speed. I'm just saying there are too many variables to hand calculate that. And a fuel flow meter (cheap) or vessel view is likely the only way he'll know for his specific boat. For example, you always hear, or at least I do that most boats are most efficient at 3krpms. My vessel view not only told me that was incorrect, but I also found out that my dash gauge is not accurate at all.

    True to some degree but a vessel view can tell you your specific mileage range or gph at a specific speed or RPM. So the advantage is significant. Hand calculating can give your averages but it can't tell you specifics. And it cannot tell you your most efficient RPM for cruising.

    Thanks Paul. Here's my current numbers 2:20 ratio 26p props 4300 wot GPS 43mph Will dropping down to the 24p 3/4 still increase rpms or keep them the same as what I'm seeing with 26p.

    I'm thinking about going from 26p prop on my bravo 3 to a 4blade/3blade 24p combo. The goal is to increase wot RPMs. I know the drop in pitch will usually accomplish this, but I'm interested in what effect a 4blade rear prop will have. Anyone with this setup? My b3 is paired with a 5.0mpi.

    Look into getting the vessel view mobile module. It will tell you accurate fuel usage.

    Dead speaker

    How do I check output? Voltmeter?

    Dead speaker

    I have a dead speaker behind port drivers chair. Speaker is very faint. Confirmed speaker actually works by switching with another speaker. All connections are good and I can't find damage to the speaker wires, granted they are wrapped in conduit. How difficult is it to run new speaker wire? What else can I check? I verified all settings on head unit are correct. Possibly a dead channel on head unit or amp? All are JL Audio.

    B3 gear ratio

    You might have a point...

    Vessel view mobile on 5.0mpi

    Their website also shows which serial numbers will work. On mine the engine cover also says "smart craft" equipped. Had a #$^% of a time finding the port to plug into on my engine, as it was dangling off the back of the portside. My 04 engine only had the weather cap on the plug, so you will have to buy a yellow terminator cap, as the earlier engines didn't have the terminator cap.
