I am replacing the 20 KW Kohler generator (model ROP 63) from my 56 MY. I am having a little discussion/debate with my generator fellow who is reluctant to remove the old unit without a forklift coming through my pilothouse door. In order to avoid any damage to my boat, I have told him that I am willing to pay more in labor time to have someone strip the unit down (I know the rear end comes off because I replaced it already) and take it out in pieces if necessary. The new one can be put in in two pieces no big deal. The issue is the weight of the block after the rear end is removed (and even after the head is removed). Does any one have any thoughts on this and the pros/cons of having a forklift involved. Thanks.
