Although I've read most all of the threads about replacing a Sherwood pump with a Oberdorfer I'm still a bit confused as to which pump to buy. The N202M-16 (1/2" ports) or the N202M-15 (3/8" ports). Most of the threads on this site say the -16 for the Universal 25XP but when I look for the pump on the Defender site they recommend the N202M-15. The Catalina site recommends the N202M-16 for the 25XP. (Yikes!) To add to the confusion the hoses that come off the Sherwood on my boat are 5/8". I'm not near my boat which is almost two hours away but I'd like to order the replacement pump. Maybe I need to wait till I get on board and take some measurements?
