I have a 97 Volvo/Penta 5.7GL, with an SX Cobra Drive. I am looking
for the instructions or diagram to replace the impeller. At idle and
low speeds temp remains at about 140 -160 but once we run it the temp
spikes and returns to normal once we idle it again. I have noticed
that while on the hose with the flush ears not much water is
exhuasting thru the prop????
