John, its a pusher, do you think as it runs accross the water it will pick up sufficient air to cool it? , I was running it on the ground in the middle of the day when it was getting hot.
Yup thats the reason it is getting hot. Yes it will cool when you run the boat but you do not just sit there and let it overheat you put it in the water and go.
Truck on down to the hobby shop and get the recommended size break in tractor prop and if you don,t have a test stand just install this prop on the boat and let it blow over the engine, just tie the boat down.
Do your break in process from square one as indicated in the manual for the engine. Only after doing this do you reinstall the pusher prop and maybe a click or two richer on the main needle and let her rip in the water.
The AX series are superb engines and very user friendly.
