Hey guys some help would be great. I have a Yamaha 15hp 4 stroke. I've been having some problems with it. First I changed the impeller, that was shredded!! Then I changed the oil because the little red oil light was on. Well the light is still on and I'm afraid to use it because I don't want to damage it. Does anyone have any ideas or recommend a place in the south towns that is fair and honest to take it to? Thank you for all the help and it's much appreciated
