Been running a 25 Fury on my 275 Verado and has been working well. Good hole shot and acceptable top end. Ran across a gravel bar and bent the tips of the blades on the Furry and had to put my spare on for the first time. It is a 26 pitch Tempest with all plugs removed. Trimmed the motor down and floored the hot foot. As soon as I hit 4,000 rpms the prop must have sucked air as the rmps immediately went up to 6,000. I am getting the 25 repaired but now am questening whether my spare is of any use. I tried all kinds of different things to get it on pad but with no luck. The fury has all plugs removed. Puma was loaded normal , just the same as when I run the Furry. Any help or comments would be appreciated.ThanksJohn
