Hello All! Just did My Impeller a couple weeks ago. Took it out to the River and Everything was good when I was under power at low and high speeds. But when I just idled in neutral, it overheated. I believe that when I mated the Lower Unit to the Upper Unit perhaps the Hose did not couple properly??? My question is: Can I lower the Lower Unit just enough to re-align the Hose to the Sea Water Pump without draining the Gear Oil? Will I be able to see in there to do this? Going out again tomorrow so I hope to get this fixed Today! Thanks in Advance! By the Way, it is a 2006 Mercruiser 4.3 with the Alpha One Outdrive.
