We bought Toucan Dream in 1997, a Passage 450 (Hull #20). It is our understanding that the engine room was originally designed for the Volvo/Perkins engine. Not many Hunter customers wanted that engine (including us) so they changed over to the Yanmar 4JH2 series. That put the raw water pump in a very difficult place to access (on the port side) and also put the oil filter in a position (on the starboard side) that when changing, all the oil would drain out of the filter before the filter could be turned vertical. Other things were also very difficult to access, such as the starter motor and the alternator. We have just learned to put up with the poor access and also installed an access panel in the shower that helped, somewhat. All in all, though, it has been a very enjoyable boat as we still have her and she is now 12 years old. Next year, we'll put on new sails and she'll sail like a new boat!!
