Request for new engine/prop firsthand data from 190 Nantucket owners

I am sure you guys all remember this:
The graph in that article depicted performance comparisons of the Nantucket with the following engines by Boston Whaler:
Mercury 115 2 stroke
We have on board members with each of those engines, as well as members with Yamaha F150, Honda BF135, Honda BF150 on their transoms. Soon the Verados will be out in the 150 range as well. I would like to propose that each Nantucket owner on board at CW mark their performance numbers over the rest of the summer, and maybe one of use compile the data to refresh that reference article. We all may learn something new and useful, and the data would be even better than in the reference article as it would be firsthand, independent data.
What do you think? We could all collect the data and try to mimic similar conditions (1/2 tank of gas, two 200lbs men(women), cooler of ice, an Ipod, etc.).

Good idea Sal. I think the data will prove to be useful for those who are trying to improve performance or decide what prop to install when repowering their Nantucket.
Tomorrow I am trying the third prop (15.25 X 18 Powertech OFS) on my BF135. The 14.25 X 17 Honda stainless provided great holeshot but overreved; the 14.25 X 19 Honda stainless took the boat to 46.7 mph but hole shot suffered a little. I am hoping the 18 pitch Powertech will be the one. I will compile the data from all 3 props.

Sal, sounds like a great idea....Ill be testing a 16p SS Veng. and a 18p SS Vengence with Kamie on Sat. morning if all goes well.........and comparing it to the 17p Black Max(aluminum) I have on there now........send me the spreed sheet also guys:) may help documenting how the 11-2 I have does with each:)

We have to many engineers and would be engineers here. Sure, graph it, do statistics and all that is fine but the "feel" of an engine boat combination cannot be reduced to a graph. The feel of the Opti 150 is effortless speed on demand, it never feels strained, it never feels pushed, it never feels like you could really need more (need vs want--but more is always better and if more was offered I would have gotten it).
I am running the stock prop on my Opti as supplied by BW. I plan a four blade unit in the future along with tabs.

That's great Mark. I will get mine official in the next two weeks, and perhaps even this weekend. Thanks to Henry as well (PS you want to be called Henry or Yiddil here?) Also, if anyone has any sugggestions on how to conduct the tests, please chime on in.
I found that whole initial discussion extremely enlightening; too bad I ignored the data and bought the dog. Gazing at that data though, any owner of a 115 4 stroke can improve their midrange cruising by using the aluminum black max instead of the stainless prop provided.
I know the feeling you are talking about. I feel it often as I pass Nantuckets running Optis (wink). Seriously, putting this together would be valuable to other prospective new and used Nantucket owners, and a way for us to contribute something back to the forum, from which we have all taken much.

Perry , the Honda stainless 14.25x17 yields real nice top end. Is that with your bimini up?

Sal, the 14.25 X 19 propeller provides the 46.7 MPH top end. The 17 pitch prop provides the great holeshot. I'm giving the 18 pitch a try this afternoon. Speed was recorded via gps with no bimini.

There is an article in TRAILER BOAT MAGAZINE this month on the topic of 300 props that may be of interest to some here. I was just looking at it at Barns and Nobel last night.

Guys, you have me perplexed...my dealer owes me a free stainless steel prop for my 2005 Nantucket with a 150 Opti...what should I select?...I am clearly not an engineer just a novice. Thanks in advance. Best and thanks again to Mr. Jim (the owner of many boats, but especially of the nicest restored Montuak on Lake Erie, all done in 6 weeks!!

JoJo - check Whaler.com and see what prop they tested your rig with. I think you will want either a Mirage Plus or a Revolution 4, either fitted with medium vent plugs. He may try to give a less expensive Vengeance or even aftermarket prop?

I tryed a 14P SS Vengence one day on mine and she would not plane....now have the 18P and 16 P to try maybe this weekend..I belive LHG said in a prior post the 18P would give me 42.60 or something...Cant remember what you said bud....Sal, Either works for me...Ive been called worse:)hehe. My WHaler dealer thinks the 16P may work better, but they were the ones that recommended the 14P...maybe they misread from the 115-4...:)

I finally got around to testing some SS Vengence Props on My 115-2 Nantucket and Im very confused about the results. Kamie helped, but what I found was very puzzling!
The 16P prop went on first(thanks Kamie) and with a slight wind, Bow dodger and Bimimi all open, she did pretty much the same WOT speed as the Aluminium Black Max 17P...maybe 3 MPH faster, but she jumped up on plane real quick...puzzeling was the WOT was the same as the Black Max...5270-5300!!! Id there a Lock out so it cant go higher???? Top speed as I said was maybe three miles per hour faster, but no 42...more like the mid 30's, just like the Black Max???? I have repainted the bottom a few times and Im wondering if to much paint could add to the confusion Im having???? The 18 P...did exactly the same...except it clunked in Iddle, so I went back to the 16P...anyone out there help me understand why this is happening????? I thought I was going to get 37-42 Did LHG say that in another post???? I forget... If your out there give me e a buzz:) Full tank of gas and just me on "Das Boat"...Kamie did all the heavet lifting ...thanks, one bad hand...Thanks

I sent my data, as well as Mark's (150 Optimax) , in an email to our moderater. When you get the chance perhaps you can do the same?
Or if Jim is busy (and he probably is), and on his command, I would be happy to put it together in one sheet/graph.
I did not mimic the numbers CaptReils and I attained on a 50 degree dry day this past December. Nevertheless I am happy with the performance of the combination. My top end speed was 47mph, and not 50mph, probably due to (1) the bimini being attached, albeit folded forward, (2) the temperature being 82 degrees and humid, and (3) a good chop to the bay, as compared to that December day where the water was like glass.
Hope you all are enjoying your summer weekend.

Sal, can you send me that e-mail too? I'd like to compare the data to what I have recorded.

I did send the emails; hope you guys got them. Anyway... here is typical summer performance for me.
