Took my 1987 Carver Aft Cabin out this weekend and noticed that the Starboard Engine Temp gets real warmer (i.e. about 200F) when I run it in idle in and out of my Marina. When I get the engine up to over 1000 RPM, the temp comes back down to 150-160, normal. I have looked at the exhaust and water is being flushed out at both Idle and Higher RPM, little less water than at idle. I believe it is time to change the impeller as I haven't noticed any blockage in the strainer.

Are there any good tips/videos out there regarding changing an impeller on a Crusader Engine? I looked on You Tube, didn't find anything specific to my type of engine. Access to the pump looks kind of tough, cover has a belt on it.

Any advice would be appreciated.

Thanks.
Scott
