New Owner with questions
Just bought 1978 V20 Steplift with Mercruiser 470 I/O.
Does anybody know where to get a manual? Also what is the normal operating temperature of the Merc 470? I took mine out on the water and it was running at around 160 at idle and 200 on plane. And how do I replace the raw water impeller/where is it located? Any answers will help. Any tips on care or what to expect to break would be appreciated. Thanks!

Any Mercruiser dealer or online you can get the manual of that motor, it will run around 100 bucks if not mistaken. The impeller is inside the lower unit, you have to lower/remove it in order to get to the impeller.

Yeah the impeller change is next on the list once I get the part. It's getting good raw water flow from what I can tell. Of course this is a new boat to me and I cannot tell what's typical. I think there might be a buncha junk in the fresh water system. I'm going to flush it out today and see if that helps. When I come off plane, the temperature climbs dramatically. Any ideas? I'm thinking possible blockage in the fresh water system.

If you are getting good raw water flow, then it may not be your impeller. Is there enough antifreeze in it? Maybe its the thermostat.
Word of advice: If someone else chirps in, they will probably be more knowledgeable than myself. I am not a mechanic and a relative newbie. However I am not just taking a break from changing my oil pan. rkc
