I just put on a brand new 13 1/4D 17P hustler prop,<br /> I now have what feels like a slip when I'm almost full throttle. If I do not cut back a hair it would most likley go to 6000 rpm's but will just as quick go back to 5000 rpm' and stay there as long as I'm full throttle.<br /> So to be carefull I go 3/4 throttle and resume to full very slow. And It will stay at 5000 rpm all day.<br /> The only difference is the new prop has three ventalation holes on it and the old prop has none.<br /> I'm not even sure why I can not get 5500 rpm's out of it. But one thing at a time.
