Are Speedmaster elec fuel pumps any good ??

vane style can get mucked up over sitting. The vanes get stuck and prevent the electric motor from even starting. I bought a pair of Mercedes 560SEC pumps for nothing as they were both stuck. 18V applied about 10 times and some WD40 freed them right up. So many EFI boats out there getting new fuel pumps when theirs are found to be locked up after the winter. A boater I know knew a young man who was smart enough to advertise "boat starting service" for the marina he lived next to. He would start stored boats on a sliding scale once a week or month for 5-30 minutes (or just cycle the pumps) for a small fee. He got so many customers that he had to hire 2 other guys. Dont know what type of liability insurance he had but that would be tough today...running a boat without oil or something...
