Does anyone know what size bilge blower is in a 2010 Sundancer 390? My starboard side blower is tripping the circuit breaker, and I was trying to order a new one before heading back to the bilge. the parts manual says 4”, #250M. Does that indicate a 250cfm 4” fan?
I've had this guy in my Amazon list for years as a reminder of what I think I need if/when mine fails. Someone around here must have linked it at some point. Seems to match with what you saw in your manual.
If his is original he has intermittent duty axial fans probable made by Rule and probably 7 amp circuit breakers through the blower control module. I upgraded to the continuous duty centrifugal Jabsco units but had to change the circuit breakers to 10 amp.
Oh... you might also try spraying some PB Blaster or silicone spray into the shaft/motor and then giving it a kick start. It might last for a week... it might last for a couple years that way (especially if it's used regularly). Or it might not work at all
Nothing caught in the blower. I sprayed some lube in there and will give it one more shot. This is the factory unit. https://www.amazon.com/SEACHOICE-Exhaust-Blower-Flange-Mount/dp/B0773SHZTS/
Mine were both replaced last year with oem replacements. One kept tripping the breaker and figured might as well swap both. Much quieter.
Had I known it was a $40 fan I would’ve purchased two of them and just swapped them. At this point I’m going to see if the lube does the trick, if not I’ll buy two of them and replace. 13 yrs out of a $40 part is perfectly acceptable to me.
