A Missed Disaster

[HunterMP]

I have 3 .21 K&B outboards and all most had a disaster in the motor I normaly run. Since my cousin

recked his boat 30 seconds after he put in the water he wanted me to run his SS. Since I had my motor

off and its been a few runs since the internials were looked at I decided to check. When I pulled off

the top half with the crank the bushing for the connecting rod came off then I noticed the end of the

rod was cracked. I think this could have probably caused a little damage.

Throught all that I have a prop question. I currently have a prather 215 on a K&B 3.5 with a Irwin

quite pipe is a octura x440 a better prop for this situation since I don't get the rpm's on a full tank

of fuel? It the best with a 3/4 on down. I now the prather has more pitch and dia.

Re: A better prop

I think the X440 would be a much better prop for that application. I run the X440 or even X438 on my mod motors. Another prop that works well is a X640 that had been reduced in diameter to 37mm.
