I have a 1986 50 hp. Yamaha, it well run fine out of the water, but when I put the boat in the water and take off, it well take off fine but about 200' it well drop from 4000 rpm to 2500 rpm, it well not die, it idles fine, but when I take off again it well not get over 3000 rpm. I just got it out of the shop and he rebuilt the carbs he said
