A hook, drives tucked in, the tabs all the way down and 4 fat chicks (I'm talking huge) won't scrub 15 mph off the boat.

Well there was, past tense, a 1/4" hook in the last 18" of the boats bottom. AT told him it was nothing to be concerened with. I convinced him to remove it and the rest is history.

Yes 15 mph differnece. Can't argue with facts.

Well, if that was the only adjustment made I am amazed. If the engine and prop remained exactly the same then I retract the fat chicks remark.

Perhaps the surface drive changes charecteristics. I know on the Pulse Drive the 22 had a small hook but it was the DDC bottom and it scrubbed a little less than 5.

I know someone who had a 32 baja about 15 yrs. ago and they took the hook out and it sped up but what a sh*tty ride ...the faster you went the more it porpoised and needed more and more tab to keep the bow somewhere near level..so there went your speed gain..so it's best not to f*ck with the designers design..but you can feel free to argue the factories x demensions sometimes:p

Yeah but the newer 28 is the old 32 hull so it doesn't need the hook to ride.

But I have to say the older 28 hull with twins got my attention a few times! :eek:

Yea, two guys, one guy empty on fuel went 69 no matter what propeller he tried. Jess put every cleaver combination, rake, diameter, pitch, # of blades. Then I made a new thrust tube to put a Bravo 1 propeller and a Maximus and the boat was stuck at 69. Utter failure.

Then I asked about the bottom, he was very reluctant to touch it as he has never done anything to fiberglass before. All he did was take a grinder and take the hook out and the last 18" of the boat it put a smile on his face "Full of Fuel" with two people!!

Now the 22' you refer to. If its the same one a father and son run I think out of the Mid West, then that boat does not like the Shoel drive according to them. Had the 28' been made with a step or Rocker, then things would have been a lot faster a lot sooner as far as a Surface Drive application is concerned.

Looks like it runs well. :evilb:

Rik said the target was 90 mph, did he make it? Doug

Have you made it in the water yet Doug?

1/4 of hook alone was worth 15 mph!:bsflag:
