I am new to boating. Bought a 290 SLX with twin engines and love it. However, when I get up on plane and try to trim it even a little, it begins to cavitate. Also, it goes great at about 3000 rpm and 30 mph but if I try to go more slowly it will gradually lose speed and basically stop. How do I maintain it in the 20 to 25 mph range?
