Im asking this for my brother again. He had a used 1999or2000? 300 promax put on his Lavey 20.8 sebring by Lakeland last month. The question is, IS SOMETHING WRONG? It is a dog out of the hole! He started with a 26 Bravo with big releaf holes, that didnt work. He has also tried a 22 Bravo(still sucked). Bro has tried the jack plate up and down on take off, Ive allways dropped my motors all the way down on take off, then trimmed it up. Richie has said that he is trying to push to much water??????? I would think a 300promax on that little hull should fly out of the hole. It has a sportmaster lower with 1:62 gearing(which is over heating with a brand new impeller neet) Any ideas?
