Breaking : For the last time - if you have a prop larger than 15inches diameter, you are most apt to get hull buffeting!!

Your boat, your choice

A thought
No repetition needed. I have no intention to buy a different diameter prop, and don't recall ever saying I would.

I just want to know what other people have on their boats so I can request an adjustment by Atlantis. They're very reluctant to increase pitch by more than 1" in one shot, so if PropScan says I have the factory default 15"x9" prop, I'm going to have to push him a little to increase it to 15"x11". If there's clear experience from multiple people that 15"x10" is still too little pitch for an M35B, it will help raise my confidence to push him to go to 11" pitch.

Last I checked, most prop shops don't have the technology to increase the diameter of someone's existing prop.  :D  But if by some chance someone here has a smaller or larger diameter,  I want to know about it.

Breaking : It's the process "Prop Scan" that is important - measuring multiple zones of the prop.  I have no reason that Atlantis shouldn't use it as well as BlackDog does.   :D

My thought
Thanks, Ron. I found your 1991 Tech Note where you took it to your local shop, but having a hard time finding the article from several years later where you went to Black Dog. Do you have a link?

I'm also interested in hearing from anyone else with a M35B motor. What diameter/pitch do you have on your props? What is your maximum RPMs?

I'll be taking my prop to Atlantis sometime this week, so would like to know other owner experiences.

Thanks, Ron. That's EXACTLY the type of advice I'm looking for. I'll also check out your articles, but it sounds like my M35B should easily handle 15"x 11" without lugging the motor. I'll probably request this to start, and maybe request further tweaks next off-season.

Atlantis Prop is about the only shop within 40 minutes of my home. Their website also says they have prop scan. Are you aware of any reason not to use them instead of Black Dog?

Breakin Away, try it now.
I tried again. Same result - it says no user by that name. I still think that someone should try creating a new userID to see if you can replicate the issue.

The website is also still not secure.

Thanks, Stu, I look forward to trying it. But I'm going to hold off on entering any credentials until the website security issue has been explained: http://c34.org/bbs/index.php/topic,10100.0.html

Since this thread is dedicated to tech issues with the website, I'll also point out that email notifications of new posts has stopped working for me in the past day. Not sure if this is also connected to the other problems.

I noticed the same thing that last couple days. Not sure when it started, but pretty concerned that I may have been entering login credentials to an unsecure site. I'll continue to use it as long as I don't have to log in again, but going to be real reluctant to enter my credentials again if I get logged out.

Also, I have been having severe login problems for editing the Tech Wiki, and it has been insecure as well. Is is possible that something has gotten hacked and is causing these issues?

I called Ray at Atlantis Propeller today and had a talk about my prop. Like Noah, he expressed some skepticism that my motor could have been actually revving at 3800 RPM, noting that the governor should prevent this. I'm so clueless about this stuff that I didn't even know that my engine has a governor, but after reviewing the service manual I know it has one, but I'm still pretty clueless about how it actually works. It seems it has to do something with springs interacting with the centrifugal force of the governor shaft to increase/decrease fuel flow if centrifugal force decreases/increases when load increases/decreases. But I digress.

I told him I'd do some homework and bring the prop by next week when I'm back home near Philly . In the meantime, I need to decide whether I should request any modifications to the prop. I assume that I have the standard 15"x9" three-blade prop (with pretty narrow blades) that Catalina supplied, and I'm sure he'll verify dimensions and pitch and tell me if it's something other than 15"x9". Since the boat is winterized on the hard, and I do not want to do multiple short hauls to seek perfection, I'd like to take the long-term view and get the prop little better for the coming season (i.e., RPMs closer to 3000), then verify top RPM after launch in the spring, then have him do a final prop adjustment (or replacement) while hauled out a year from now.

I'm always inclined to leave well enough alone, especially since Mainesail says too little pitch is better than too much. But knowing that I have the more powerful M35B engine, and reading here that there are people with M25XPBs who upped their pitch to 15"x10", I wonder if I shouldn't have him up the pitch on my prop to 10" (assuming, of course, that it hasn't already been increased). Then I'd check my max RPMs next spring, verify it with the strobe (since I haven't used the strobe above 2400 RPM), and do the final adjustment while on the hard in a year.

What do you guys think? Of those of you who have the MkII/M35B combination with 3-blade prop, what prop size and dimension do you have? Have you verified that it achieves a max RPM of 3000?

My profile says Breakin Away is both display and sign in.

Your experiment with changing your password is a huge red flag that the credentials are no longer connected to each other. Credentials seem to be the same for legacy users merely because they haven’t changed them.

All you guys need to do to replicate this is log out and create a new (temporary) userid for yourselves. Then I suspect you’ll have the same problem. If not, the problem may be unique to me.

Ditto for me, I've always had the same problem. There must be some piece of the puzzle that we're missing.

Did that process change at some point?

No.
Please let me know when you've figured this out. I clearly cannot log on with my credentials, even though I've followed them exactly. The screenshots pretty much tell it all. Since there's never been a change to the process, then something must have broken in the back end. Meanwhile, I'm sitting on some nice contributions that should go into the wiki.

Thanks!

Check you tachometer for accuracy before you make you decision to repitch based upon an assumed RPM of 3800.
I checked it a few weeks after survey (and annually since). Spot on.

EDIT: To be clear, I've only tested up to about 2400 RPM, but everything is accurate and linear. I'm not sure I want to be around the motor when it's spinning at 3800 RPM.

Oh, one other thing.

Ken's userid on the forum is KWKloeber.

Ken's userid on the wiki is Kloebereng. Not the same credentials.

You might want to check out some of these facts before yelling at people.

I tried Stu's method again, which was the same thing I had already done before trying Ken's method. Since this is the third time I've tried the same thing, I also decided to yell at my computer.

It didn't work.

Since you clearly don't believe me, I've attached screenshots. I think you have a problem, and hope you come to realize it.
