I went through almost the exact problem a couple months ago. My 3hp was overheating. I though the water ports around the cylinder where plugged. I broke 3 of 6 head bolts. For future reference get a reverse twist or left hand twist drill bit. Drilling the bolts out one backed out on its own. I...
I have a 1972 lowboy that I have used very little in the last 20 years that I would trade for a 3hp ducktwin in decent shape. If interested send a pm.

There was a great flow out it was going strait from the pump into the exhaust port and out. Without the grommet there was not enough pressure to circulate water around the cylinders.
I guess I am old, I don't really think of a mid 90s motor as vintage.
It is still running hot and I noticed there is no water tube grommet. All this monkeying around and I bet the pressure with the grommet would have cleared the port.
Thanks guys. I know it is going to run like crap until I get all of the PB blaster out of it. I want to get it running tomorrow and take it out to the lake and run it wide open. That seems to get it cleaned out.
PB blaster worked on two with left a hand drill bit. I drilled and tapped the third. I got the motor back together. I will gas it up and give it a go tomorrow. I am waiting on a new head gasket but the old one was intact. Fingers are crossed and I think it will cool now. Does anyone know how hot...
I noticed my 1961 3hp evinrude was running hot. I was getting good flow up to the check screw but the water wasn't making it around the cylinder. I decided to clean the path. While attempting to remove the head, I backed three bolts out with ease the other three had no temper left. I put little...
A couple changes in the carving comp this year. We have moved it to Sunday at 11 am in the high school gym. We are also still taking vendors at this time if interested. The dates are as follows Sept. 20-21. http://www.pymatuningexpo.com/
x2 on the Benelli and breakfree CLP, I had the exact same problem with my SBE 2. That was two years ago. This winter was way colder here and no issues.
I dug out an old burlap bag and am going to give it a try. I have several sheets of camo clad also. That will be my second option. I have thought of repainting in the old ducktwin colors but again I hate to paint it. I really paid next to nothing for the motor$80 +$20 for a carb kit. It didnt...
