HI, I have a 20 cajun bullet rigger with a k&b 7.5 in it. This boat humps really fast, when it is running. Since I replaced the picco 20 with the 7.5 I have gone through 4 sets of bearings!
History on the motor..
I bought it new from a hobby store ,It was new never run and saved in oil for years.
I broke the engine in on 15% with 4 tanks and 2 tanks of 30%.
This motor had alot of compression and when it got "loose" I started running 60.
She blew the first set after 3/4 of a gallon of 60%.
Second and third set came 8-16 oz later, now I'm on the 4th, and I would like to find out why before I blow them. If anyone has any tips on why please help.
Thanks in advance, I'm OUT or parts!
