sea water circulating pump and other ?

[dave250boater]

2002 Mercruiser 260hp Alpha- raw water cooled- in regards to the sea water pump (on the block)- are they typically metal impeller or rubber like the outdrive?<br /><br />Also- going to change plugs in this engine- any replacement type (AC Delco, Champion, etc) - recommended more than others?<br /><br />Are remote oil filter kits worth it? With the inverted filter they seem like they make more mess when changing..

Re: sea water circulating pump and other ?

the water pump (on the block)is metal but it uses marine grade metals inside like bronze and SS to stand up to raw water<br /><br />i here great things about AC plugs and nothing good about Champion<br /><br />remote filter depends on if you motor install allows the filter to be changed some do some dont<br /><br />tommays

Re: sea water circulating pump and other ?

To further clarify the pumps. The sea water pump (aka raw water pump) is a rubber impeller pump in the outdrive, the pump on the front of the engine is known as a circulating pump, and only circulates water through the engine, not into the manifolds.<br />Like tommays said on the plugs, AC, NGK, Bosch plugs are all great plugs.....avoid Champions,
