Cutting Edge prop should be interesting. On the Turbo Fusion4 do you feel that you just needed a bigger wheel than 27? Here is another 28 Offshore with a single. I have not seen a single since yours.

Greg,
I am just guessing that the Fusion 4 diameter was the problem since I had gone up in pitch. After trying the Cutting Edge, I might consider a Hydromotive or even a Mirage Plus 3 blade since the drive is definitely low enough that cavitation should not be an issue. I probably should have gone with the Bblades prop trying service which is not out of the question after the Cutting Edge trial if I don't like the performance. It was a perfect day today with no chop, but I did get to take a large cruiser wake which the Warlock ate like a hot knife through butter. I intentionally did not slow down since I wanted to see how it could take something decent sized.
I am a little surprised that another 28 came available with a tranny setup - there would not be enough room in mine.

There is a guy running 700hp in a Team Warlock 24. He is running a labbed Bravo I four blade from bblades on his Team Warlock as a point of comparison for you Bill.

Here is one of the 2 access holes I drilled with a hole saw - one on the other side, too. You can see the steering arm bolt that needs to be loosened along with the top retaining nut which you can't see.

84 and 85 on GPS Bill. Here is a blurb on props that might be a help to you as you dial the TW 28 in ............
It depends what you are starting with. Bravo 1's are a little smaller than advertised, starting with a 32 you are at 30 1/2 to 31 true pitch. Labbing removes material and blade area so even if a little "cup" was added, you are in that general area. Cutting Edge props act slightly larger than advertised due to their additional "cup" so Bravo 1 and CE are not exactly the same as advertised. In an apples to apples comparison of the same brand, same pitch, same blade style you would normally drop a number of pitch for an additional blade (going 4 blade to 5 blade). CE has two different blade styles available, the Bravo style round ear and the Hydromotive style semi clever. With the round ear I'd go down at least a full pitch going from one on their 4 blades to one of their 5 blades. On the Hydromotive style, its less than half a pitch difference compared to one of their 4 blades due to less blade area.
I have a CE 29p 4 blade with extra cup, a 32P 4 blade and a 32p 5 blade hydro style. I've found that my boat likes the diffuser removed, added cup and a diameter of 15 1/4" or less.

I would have thought that a cored hull was also lighter in total weight, but I guess that is not the case.

Once I discovered it was a cored hull and I saw some of the glass work that was visable, I realized that it was a very well made boat. I have never had a cored hull before (deck only), but I always thought it had to be heavier than a comparable non-cored boat. How much heavier I figured was how much the extra coring and glass work added. The added bonus of knowing the hull is stronger is how quiet the boat rides. It is like adding sound deadening materials in a car - huge difference in splashing noise.
I finished installing a Mercury 4000 throttle instead of the Lavorsi I had bought yesterday afternoon since I liked the feel of the ergonomic handle on the 4000 better. The rubber grip handle fits comfortably in your hand. It does not feel cheaply made like the 3000 did, plus it does not have the separate trailer button. The thumb operated tilt button takes the drive all the way up or down. In my case, I did not have to use the throttle kill switch since the Warlock came with a kill switch on the lower dash. It looks just like this one. http://www.ebay.com/itm/MERCURY-8837...ht_3578wt_1170
I now have to get the steering arm and swivel pin replaced and I'll be ready to rumble.

I see the number 75 in your future Bill. One other thought I had regarding your 28 was the strake design. You said the 10' straight edge showed the hull and strake running lengths to be dead flat, which is pretty amazing for a boat that old. On the strakes however, are they flat port to starboard? Team Warlock was experimenting with slightly different reverse angles on there lifting strakes early on, and I do not know if they ended up turning them down a few degrees in there production hulls to provide better lift to those rascals.

The strakes appear to be flat with no angle to them, and the bottom of the hull is very straight with less than 1/8" deflection over the 8' straight edge I held on various areas of the bottom from the transom forward. Here is the throttle I installed last week. It feels great in your hand and has no trailer button to push - the one switch does all the trimming.

Bill,
If you want to try both right and left I still have my Cutting Edge 30" set...

Marshall,
Thank you so much for the offer. I don't think my boat will spin anything over a 26 or 27 pitch. In addition to finding the best overall prop, I am also trying to figure out why the boat leans so much to the left which might be related to the style prop or to other hull/drive factors. Thanks again. Bill

A narrow beam hull with a deep V and zero pad will sometimes demonstrate this tendency and it can almost always be corrected with prop dial in. Hell my 16 would do it depending on what prop I was running at any given time. Curious though to be more specific, are you seeing it lean left as you are coming up on plane? At cruise say 3000-3500 RPM? Does it go away at a certain RPM and Speed?
