I recently purchased a 88 28.5 Hunter that has an inoperative head. To the best of my research its a Sealander 752. Ive read many posts by the host of this forum (The knowledgeable Peggie Hall) stating the uselessness of rebuilding these units due to costs, reliability, and availability. I'm considering the Raritan PHC conversion recommended but the boat is currently stored 4 hours from my home, long haul just to measure the base. Has anyone done this conversion? Will the bowl fit? If it doesn't fit, is the bowl available separately? Thanks in advance!
