buddy just purchased an 05 38 slingshot w illmor 550's n arnesons didnt get any water coming into the strainers unless engines were 1500 rpms or higher. my question is regarding the raw water pumps on the v-10's. do they use the same impellers as merc ? once run dry and over heated are they shot ? any assistence would be helpful.
