hi,I'm in a bit of quandry on what model engine I have.according to the old spec manual my bore should read 3"3/16" but my engine reads 3"7/16+-.I know it could not bore that far,so, my 620 could be four 162? my engine number is:blockF400A5020 g60wc trans:g2603 5/11/55.Any help would be appreciated. |

Looks like a 162 block with a 620 reverse gear on it.
There is some Graymarine info posted at http://www.finewoodboats.com/Gray.htm |
