Hello all,

I have a 1997 johnson 150 (60 degree) that I am rebuilding myself. When I installed the first rod and piston on the crankshaft and spun it by hand, I noticed a very tight spot at one point of the rotation. I then put four more in and it felt the same. After I put the last one in, it got worse. Does anyone have any suggestions about what I can do to correct this issue? Another thing I have noticed is that the crank bearing housings do not line up perfectly where they are broke even though I am positive that I have them on the locating pins properly. Is this a big issue or will they seat properly when the crankcase is torqued down? Thanks.

Did you mark the conrod caps so they went back the same way around?
Ive had those crankbearing housings off line before and nothing untoward has happened after many years. I suppose it depends how off line yours are, mine have being about 1mm
