I finally have the engine running great after having fuel and ignition problems were overcome. Now it's overheating when I apply power. At first start the engine comes up to temperature slowly and stays in the normal range (180 - 200 deg) until I apply power. Then it starts to rise slowly for about 15 minutes until it looks like it's going to overheat and I throttle back. I keep it a few RPMs above idle idle for a bit while it cools down. Then I try again only this time it overheats after 5 minutes at power.
I checked the impeller, back flushed the oil cooler, lines and outdrive intake. Pulled the plugs out of the backside of the manifold and flushed out the crud. All with same result. Ideas please.
