    I would keep a spare HD solid hub with the Delrin strips that just slides in by hand. It can be used for prop testing and as a spare if you have to change props on the water. Let's see what Don...

    That would be an excellent question to ask to several prop shops that have accurate measuring equipment and many years of experience with various props.

    Perhaps the following is easier to understand. If you could weigh 1 cubic foot of air, it would be denser and weigh more in the winter conditions. So at the same rpm, the engine would breathe in more...

    When the temperature and humidity increases and the barometric pressure drops, the "density altitude" of the air decreases (less oxygen). A hot humid summer day might have a density altitude of 3000...

    On my boat the Bravo 1 has much better holeshot than the Bravo FS. A 26P Bravo 1 planed every bit as quick as a 24P Bravo FS. However the Bravo 1 had more stern lift and required more trim to lift...

    I think they meant that the Clean Power Harness (small gauge red and black wires from the engine) must be directly connected to the battery posts not to any switch. The heavy gauge main battery...

    I think you should have 3 washers, the large thickest one goes on first, then the thin smaller diameter cupped Belleville washer and then the remaining washer which is a bit thinner than the first...

    Can you remove the fuel sending unit and siphon it out of there? Or can you remove the fuel line and attach a hose to the barb fitting and siphon it out that way (you might have to remove the...

    I waited until my 300R told me it needed plugs. It started to have a misfire that felt more like a speed change up and down. There was about 80 hours on those plugs, and when I removed them they all...

    Someone with an identical set up might chime in and give you some good advice. I would at least consider running the same Tempest prop you had on the Optimax (you might need a new 1.25" hub for it)...

    If it slips coming on the plane, I would try the solid plugs, since that is quick and easy to change. I don't think the solid plugs will do anything about the slip in turns. I would be inclined to...

    The needle shouldn't move when you use the trim switch (at least mine doesn't). When I use my trim switch, the voltage drops due to the current draw, so I would check your wiring and grounds on the...

    Not sure to what extent your fuel gauge needle is moving. If the sending unit is near the back of the tank, and the tank is not completely full, when you trim up, all the gas runs to the back of the...

    Not sure what your max rpm is but I would think that going from a 16 to 15P of the exact same style of prop would only raise you WOT rpm to about 5200. However if you stopped trimming at 4800 due to...

    I'm sure Mercury engineers have calculated all of this. I doubt they would supply an intake grate that was a restriction to the point that you would lose 1 mph at WOT. Of course that is purely my...

    Is it possibly "prop rattle" from a worn hub or incorrectly installed prop washers or torque? Does your prop have a pressed in hub?
