1 just wondering what all the fuss is about marine water
pumps? a car one costs about $50, a marine
one 10x as much. why do i 'need' an expensive impeller when a car-style metal paddle wheel
would work as well? (the thing really irking me is that my existing 40yr old jabsco
has an impeller driven by a 3/4in drive from the engine
, and the seal for the shaft is proving very difficult to find. it appears to come as a kit from jabsco
, costing nearly $100 . quite an expensive annual cost...
2 query the second, is if i choose to marry a spare if antiquated jabsco pump to the 3/4in gear
driven shaft from the engine
, how would i join both shafts 'male to male'? i assume i could use a propeller
shaft style boss?.
any thoughts people?
thnx in advance
