You are absolutely correct. Went back and reread the original post and realized my brain saw 300R even though it never existed! Thanks for the correction.

You are absolutely correct. Went back and reread the original post and realized my brain saw 300R even though it never existed! Thanks for the correction.
I believe the 300R has the higher 6400 rpm rev limit, short runner intake and different intake camshaft.
I think I read the same oil wear test reports to ifishinxs and was also surprised at how the 10W-30 Mercury synthetic blend excelled in wear tests against almost any oil available. Better than most...
I believe Don had a post on 4 stroke break-in, in the frequently asked questions on the 4 stroke forum. I think the manual meant to run it at 6000 rpm for no longer than 1 minute, every 10 minutes or...
Definitely does not look like a surfacing prop. Most tests I have seen showed a bit better efficiency but not quite as fast as current go fast props on lightweight boats.
The center round piece is the anode and it is easily replaced, just unbolt it and install the new one but there is water behind that anyway. The other scratches are on the cavitation plate or the top...
Another member posted that he removed the cowl on a fast Bullet that ran in the 90's and there was less than 0.5mph difference with and without the cowl.
I just opened the access door today (never removed the cowl or air inlet ducting. It was definitely noisier and both my wife and I thought we were going faster. However the GPS recall settled that,...
The soft limiter won't allow it to exceed that rpm (on a Pro XS). If that was the case, you would likely move up in pitch so that you could turn the higher pitch prop close to 6200 rpm.
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...
No, my first name is Glenn
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)...

The link above explains how to check the sending unit.
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...
Yes, but replace the wing nut with a stainless nylock nut. See the FAQ sections on batteries for more info.
