With 20% slip as is I don't believe raising the drive height would be a good idea.

I think I would find someone with some scuba equipment to go down and get that prop if I were you. What was the water depth, and did you have a GPS available so you could mark your location? I have had a friend who is a diver go down and get lost anchors for me in the past for beer money.

Hey AllDodge, any updates or more testing? I have tried a few times to email Chad Hill with no response, I am not content with locking it in as the best I can get because with being able to get to run the top end a bit finally that the bay wasn't too snotty I lost some mph from the Merc 4x3s I had on there. Boat comes up on plane really quick, with some to trade off for sure but waiting on a response. I guess I have to try calling again. I called once and they said he wasn't in but after I said I haven't heard back from him in weeks via email they said oh wait let me transfer you and he was in the building but couldn't talk long because he was leaving.

I do like the way the boat comes out of the water, the Hill 4x4 props are great. Still no more top end but I can live with how it comes up now. Thinking I might pull it out and winterize next week and put my Rinker in for the remainder of the season. Once it comes out I'll have a closer look at how the drive sits and see if there has been some kind of change I over looked.

Bought one of Hill's Bravo 3 prop wrenches, another nice piece of work. Only issue is the 1 7/16 socket is not deep enough to use with the newer style nut that also holds a zinc. Called them up and they are going to make me another and swap it out. The longer nuts would only be used by folks that leave their boats in the water so I guess that's why they haven't come across the issue. They have a 1/2 dive hole on the end so someone could use a torque wrench. I just use the torque wrench setting on my elbow

If you zoom in to the right on this pic you can see what I use. My prop shaft is drilled and tapped for the bullet zinc. I found a 3/4" impact socket that I have a 3/4" to 1/2" adapter on for the outer nut and the Merc socket for the inner nut. 100 ft. lbs. for the inner nut and 60 ft. lbs. for the outer.

I almost went the two socket direction and have the 1 7/16 socket (3/4 drive) using an adapter. Just after seeing the quality Hill puts into their goods, just went that way

Got a reply from Chad late yesterday and he is going to try doing some work on them to get me some more rpm and speed. They are on their way back to cali currently.

Sure is taking a while to get a response from OSO on a reply. I'm starting to look into pulling the motor and getting another dyno done. I just cannot get past the thought of adding 120 HP and gain nothing. Yes I have better hole shot, but for years my motor was running rich and the rebuild did fix it. So now it is running efficiently but I just cannot get past the extra power and no gain.

I would have had it out already if it was a 2 hour pull, but this is a 4 to 6 hour pull because I have to take a bunch of stuff off just to get it out. Don't want to want another couple years and finally get around to doing it and then if its less HP then the statement will be, it was but now its not.

Got to talk to my help and see if he is up for it, looking at to dyno shops in KY, so if it happens I'll post up

Were you sent any pics or otherwise told how it was dyno'd as far as what accessories were installed or what exhaust was used?

No, only told used a smaller belt so the PS pump wasn't used and it used dry headers.
