Author Topic:   can this pitch be right?

OutrageMan posted 05-31-2003 08:49 PM ET (US)
I just came back from the Mercury Prop selctor (I had to use my windoze machine because it uses a non-standard version of java that will not run on anything but MS - WAKE UP MERC).
Anyway, I wanted to find out what they would say would be the best prop for overall prefomance on a Montauk with a 90 Mercury Classic on it.
It regurgitated that a 24" Laser II was the right choice. While I do not argue with the model of prop, I certainly think that 24" is pretty tall. I was expecting to see something in the 19-21" range.
Am I being wacky, or is the prop selector all knowing?
Thanks,
Brian

Not a chance, theres no way a 90 Merc can twist a 24 pitch prop on a Montuak, unless it's about 10" in diameter.

What Sal said.
What weight did you use?
Red sky at night. . .

I didn't use a weight, I used length and boat type.

Brian,
I find the lack of compatibility with non-MS platforms that is unfortunately seen in epidemic proportions on the world wide web to be particularly annoying and especially ironic when you consider that the creator of the JAVA language is a user of the Apple Macintosh computer and Macintosh operating software.
See http://www.apple.com/pro/science/gosling/
The underlying premise of JAVA was to write-once/use-everywhere.
Of course, this was immediately corrupted by Microsoft, who invented their own, non-compatbile implementation of JAVA, and bifurcated the JAVA environment.
Of course, this is a strategic move designed to squash non-Microsoft platforms and force users to an inferior, proprietary, Microsoft-controlled product.
I have found JAVA programming that is developed for Microsoft platforms to be useless on other platforms at an alarming rate.
While I have defended Brunswick in the past for what I thought were unfounded attacks on them and their products, in this case I feel that their website is diminished by the inclusion of this cheese-ball Java applet.

Brian - I have found the Mercury prop selector to be just a little high on pitch.
However, there is a very recent thread where someone is running is the 24" Laser with same combination boat/engine. It would have to be jacked up 1 1/2" or so to acheive the top rated 52 MPH from that prop on a 90. A 22" will give top speed of 49 which sounds more like it. I would think the 22 would be best all around, but I would still run the engine up in the third hole.
For a 20" Laser II on a Merc 90, Mercury shows total load range of 1400-2300 lb, top boat speed of 45 mph. I don't think the load would be that high under most conditions, so a 20 would not be enough.
New Whaler in the works?

I tend to agree with you, Larry. I think that a 22" might be the way to go.
The boat in question is a friends, and he has a manual jack-plate on it.
