after pulling my engine for a 2nd time with a starter problem I finially resolved it after 2 years it turned out to be the wrong starter /old owner did not replace a 9 tooth starter w/ another 9 tooth instead used an 11 tooth starter which sits 1/8 in farther away from the flywheel. However my question is this should I be concerned about the engine coupler due to age ? The boat & engine is a 1996 and the last thing I want to do is pull the engine again I was very careful not to change the allignment when we pulled the motor I did run it in the drive way w/ a hose but not under any load yet , I am having the allignment rechecked tomorrow by a dealer the right way Up to this point it has not given me any problems .
