Does anyone know what would be in the way of getting a socket or wrench
on the starter bolts ?

Thanks for telling me what sizes to try. The two bolts are too close to
the rear block or bell housing to get a socket on them. A wrench does
not have enough "bite" on the bolt to losen them.

The boat is stuck at the dock and needs to get started, taken out of
the water and trailer/winterized.

Thanks
