Hello, I need some help. I have a 1981 mercruiser 470 and I finally thought I had her fixed. Got the reverse lock valve fixed, the linkage adjusted and the timing adjusted. So I took it today on the water and she fired right up backed it off the trailer and took off ran it for 20 mins and she ran like a top. I got up to about 190 degrees. Turned her off and she would not fire back up until it cooled down to 150 degrees. It did this every time once it cooled off would start right up until the last time I shut her off. I let it cool like I had been all day but when I tried to start it the crank would not turn over. I tried to do it with a screwdriver and it would barly turn I got it to turn finally and it soundlike compression being released eventually would turn alright. Well I turned the key and it fired up er a few cranks but while it was running I noticed oil spitting out the hose going to the carb from the valve cover I guess it is. Anybody know what may be wrong why it will only start cool? Every motor I have ever seen usually starts better warm. What would be the reason for the oil coming out of that hose and the crank sticking like that? When I get it started it runs great? Make no since to me. Thanks
