Does anyone have or have a hook or had one removed on their hull. My mechanic discovered a substantial hook right under each trim tab on both sides of the boat and while this looks klike it was put there intentionally, it sure seems to account for the reason that I can't get to 5,000 rpm's and am not able to break the 70 mph mark.
I was advised to have it taken out and should probably see a 10% gain in speed since it would loosen up the bow, relieve drag and probably bring up the rpm's.

Any advice out there?

My 97' didn't have the hook
your talking about.
My 98' has the hook your talking
about.

This "wedge" I'm going to call it
is between the chine and outer strake,
probably not more than a foot long.

My 97' would porpose slightly at cruise,
my 98' doesn't.

I have seen photos of my boat running
at full speed, the area in question is
out of the water, the water is breaking
at the outer chine.

If you can focus in on my avitar, you'll
see what I mean.

So, I doubt that's the problem.

What's the power ?
( usually, 454 mag's will get you over 70)

I have 502's in it and on the best day, barely hit 70mph with 26" Bravo's. The 25 Mirage's are annoying as hell as they blow out. I was advised to get the wedge removed. It just feels like the bow plows water right now even when I'm completely trimmed out and my RPM's are at 4600 at best with less than 1/4 of tank of fuel. Were you able to correct the porposing with your trim tabs? Anyway, it will not cost me anything to get this done as I have a friend at a performance shop.
Thoughts?

I have a 30' Checkmate that had about .125 of hook. I had all the hook removed with nothing but good results. Would do it again without hesitation.

Where was the hook? Was it toward the keel or between the chine and the outer strake. both side, or one? What kind of results did you get?

The boat had hook across most of the bottom from one side to the other. The boat is a single engine with a #6 and there were other setup issues as well. We made more than one change all of which resulted in more bow lift and more speed.

I have a 97 model 29 outlaw with 454mag mpi's in it, no hook like you talk about, has a slight porpose at cruise if you trim it up to much, a touch of tab are trim will take care of it, if the hook was the same on both side I would leave it along, they will have to cut into the hull past the gel to get it out then regel that area , might hurt resale, try some different props, maybe some hydomotives are lab your props, I would get the speed somewere else if it were me, and 10% is on the high side, i would think 5 are 6% to be about right, my boat will run 71 to 72 on gps with 25 mirage plus props

Outlaw, I've felt your pain. My 25' Martini had a substantial hook built into the hull. It always seemed to plow water and I could never get it to 'free up'. After filling/fairing that hook it was nothing but good things. PM or e-mail or call if you would like some more info on the procedure.

My old boat had a significant hook (3/8") on the outside next to the chine. Removing it did nothing for the speed of the boat. I did find several mph by going to a 2" shortened lower unit. The boat did become a handful to drive though.

Is the power original ?
502 MPI's I assume ?

What are the gear ratio's
of the drives ?
