    Kawasaki 750 engine: Repair or Toss

    I have a 94 JT750 jet ski engine that needs a piston, sleeve (or bore out), connecting rod and crank pin kit. I've never worked on one of these "repairable" crank shafts before and I don't know if I should bore the cylinder or have a sleeve installed, or perhaps purchase a cylinder housing. Is...

    94 Johnson 150 popped into neutral - will not shift

    My 1994 150 Johnson Ocean Runner popped into neutral under power and left me floating on the calm waters of Matlacha Pass in SW Florida today.

    1995 Johnson 150 over oiled & smokes

    After ebuilding my 150 Johnson it smoked excessively when cold but when warmed up it ran reat. Now, a few weeks later it has become almost impossible to start unless I prime the carbs with straight gasoline. Very rich oil/gas is flooding out the carbs during cranking and it appears that the...
