As asked previously, does this model have a stepped hull? I had a Larson with a stepped hull and had the same problem you describe when trimming up the outdrive. I learned very quickly, stepped hulls do not need and should not be trimmed by raising the outdrive, only use the tabs. The stepped hull already raises the hull out of the water and trimming the outdrive is too much. I loved the stepped hull, better gas mileage, very little bow lift out of the hole, no need to use tabs to get out of the hole and very quick to get on plane.
