hello i have a blown 250 verado serial # 1B530488 and i seen a post where someone has a 275 verado serial # 1B289203 power head ect.I am wanting to know if they are compatible if i can take the motor and supercharger off of his a put on mine to give me a working motor. i did call mercury and they said it won't but I'm not sure I'm believing that seems they where more just to push a new power head through them for much more$ any thoughts on this from someone that might know that has been down this road already. thread title to other post> Verado 275 long block/midsection http://www.bbcboards.net/motors/6085...idsection.html
