[QUOTE="jeffh1973, post: 303234, member: 10842"] I have the same boat, a 1996 1872MV with a 90 Johnson. It would porpoise at high speed if I tried to trim it even with the whaletail on the motor. I called SeaArk and talked to a engineer that told me to get rid of the tail and put trim tabs on the transom. He said to put 2 inch aluminum angle between the first and second outside rakes. This is what I did: I put a 21 gallon fuel tank and all the batteries up front like your fuel tank, removed the whaletail, and installed the gas charged automatic adjusting smart tabs. I now can run 45 mph with gear and two men trimmed up out of the water. I plan on posting my project when time and money allow me to purchase other materials. My tank and batteries are temporaried in and I can't make up my mind between wood floor or coughing up the greenbacks for aluminum. I wish the trim tabs could have been welded on, but the smart tabs were well worth the $150. [/QUOTE]
