Indigo Radial Winglet prop?

[ndutton]

Spencer's = standard 2 blade, yours = Indigo?

[sastanley]

Neil, Affirmative..the survey confirmed his boat still has the standard issue 12x7 two blade.

I was aware of the throttle differences, I just didn't realize how pronounced they were until I stepped on his boat..one issue is his boat goes too fast in gear at idle..I think it is set a little high, but I was constantly trying to slow him down during docking area maneuvers.

[Bold Rascal]

It's the old standard (and probably original) 2 bladed 12-7
Will I invest the time to install a tach and plot a performance curve on my current setup to compare to the new? Probably not.

Being on the Chesapeake, we have to be very careful where we venture given our notoriously shallow water depths, especially here on the eastern shore. A plastic prop would be a last choice for me given the shallows, Not to mention scad's of crab pots and always keep an eye out for other floatsum like tree branches and floating timbers.

Neil, You should also add: Increased motor RPM and HP to your list of significant changes.

Also included in this theoretical prop testing, should be sailing performance.

I would've thought that Indigo would have had to do exactly this type of testing during their development phase. Anyone know?

Lets compare apples to oranges, would be a lot easier!

BR - this was my main reason for NOT getting a CDI prop.

RC - I am with you 100%. Everyone here knows I do a lot of sailboat racing too and I do not want to be dragging a big wheel under the boat. If I recall, the 3 blade Indigo only adds 17% of blade area over a 2-blade prop & I haven't really noticed the difference. I know it is there, but...what are you gonna do?? I also know that you can 'hide' a 2 blade prop behind the keel&strut better than a 3 blade...but I've also decided that this is a cruising boat..they give me 6 seconds per mile in PHRF for my fixed prop when I do informal races. - IF I were racing the boat, I'd probably have a 2-blade Martec folding prop at 12 x 6, or even 12 x 5.

[ndutton]

If you were as serious as some of your brethren you'd have a 3 blade prop for the handicap advantage. I've even seen racers widen the strut with Bondo for handicap reasons. The handicap advantage exceeds the drag loss.

STARBOARD!!

[sastanley]

Neil, I am sure that the 6 second credit I get in PHRF overtakes the drag.

Max Munger, the class secretary in #2276 with his tall rig, owes me 21 seconds a mile (he rates 177, my boat currently would rate 198 if I had a valid PHRF cert.) I cannot imagine that the sail area from 2 more feet of mast height plus bow sprit is worth that..

As we all know, one bad tack, or missing one shift, and none of that matters.

[romantic comedy]

It is all about money!!

If we had lots of money, we could test all sorts of props. but in the real world, we do the beat we can.

As I like to say, It is a sail boat. The prop is a big compromise.

I am sure that Tom, and Indigo, has limited funds too. He has a Tartan 34, and says that he tested the prop on the boat. I have no idea how many trial props he made. My guess is, not many.

Either way, I like the prop.

[sastanley]

RC, I do too...

[Ajax]

Whoa...this Indigo prop is plastic??
Hm, I'd have to think long and hard about putting that on the boat.

My boat came with a Martec prop. It's awfully hard to give up that feature, especially because I do race informally. If I was running my fixed two-blade prop, I might jump to the Indigo prop more easily.

[romantic comedy]

Indigo prop is not plastic. SS I think. Mine works great.

we get lost in the discussions, lol.

[ndutton]

Pretty generous of MMI to provide and pay for a forum that includes the extensive discussion of the competition's product line, don't you think?

Applies to more threads than just this one.

edit:
Thanks Jerry (two posts after this one). I'm Okay with standing alone on this but it's nice to know I'm not.

[edwardc]

Indigo prop comes standard as silicon-bronze, with 316 Stainless available as a special order.

Bump...

+10 on what Neil said!

[joe_db]

I too love the ability to discuss the "competition" on here. Truth is they are only partly in competition. Moyer has done a lot to keep the A4 fleet alive and thus give Indigo a customer base. Indigo has some things Moyer does not, like the prop, PCV, and oil filter. I have products from both and could not be happier with customer service in all cases

[ndutton]

The Indigo product line would be better discussed on the Indigo forum that THEY pay for.

Look, I have no problem with their product line, their innovations or their position in the marketplace but this is like putting an ad on someone else's billboard.

[Bold Rascal]

Yet again, Why Moyer Marine gets my highest rating.
I called our good friend Ken at Moyer parts yesterday. As always he was extremely helpful and I ordered some parts (including a much desired dipstick extension, yeah!). Well, the ordered parts have just been delivered. Less than 24 hours standard UPS ground. AMAZING!

Thanks Ken and Moyer Marine for such a great forum, support, parts and Excellent service..

[joe_db]

AFAIK Indigo has no forum and Moyer sells no props

Exactly to Neil's point

[Bold Rascal]

Moyer Marine does have a forum discussion category specifically for "Drive Train / Propellers".

Speaking only for myself, I'm extremely pleased and appreciative that MM supports this kind of group discussion and edification.

[joe_db]

If we deleled all the posts about Indigo PCV systems that would be 1/3 of the forum total posts right there

[ndutton]

I'm not trying to deny Indigo's existence. As they offer A-4 specific products I would expect their name to pop up from time to time but this thread was specifically about a product of theirs and went for 38 posts before I'd heard enough.

MMI has extended considerable effort and expense to establish a customer base and this forum plays a major role in that effort. It seems to me it deserves a little more consideration and respect than I'm seeing recently.

Okay, end of rant.

[joe_db]

If Moyer was selling a prop your rant would have a point. But they don't and the Indigo prop makes the A4 a better engine and thus makes people want to keep them more and thus gives Moyer a bigger customer base and thus everyone wins here
