Except one problem neither the merc or the crusader comes in RH rotation only LH rotation, so what do you add in the price of Bi Direct V drives and re-engineer the whole engine compartment? I still say go with the 5.7. Crusader will sell you both LH and RH in that model either as bobtails for about 15k or with reduction transmission for less than 20k as compared to 6.0 with Bi Direct V drives will set you back 25k plus the whole mess of re doing the commander to fit them in. I'm trying to base this on what Dave Mehl posted originally not just the apples to whatever comparison of the 2 different motors. I am thinking how I would do it based on his post given overall costs and ease of installation. I would not want to have to re-engineer the boat to make a motor work and I am not a big fan of V Drives. I understand their application for smaller express cruisers and the added savings of room they provide but room isnt an issue and I would take straight inboards over v drives any day (just my opinion). Now I know you will find some one making the 6.0 in a RH roatation but for how much? And is it worth the additional cost? He is talking about resale value down the road and ease of someone else posssibly replacing with big blocks. I'm not saying the 6.0 isnt a great motor I just feel the 5.7 is a better choice in this instance.
