It's been a while but I'm back!
I need some help with a boat I have always wanted, and finally was able to buy. She's wearing twin evinrude 110's, model numbers E110TXCCA.
It sat for two years, but had been running prior to that point. So I decided to do some maintenance before getting it in the water. I changed both impeller/water pumps, gear lube, spark plugs, fresh gas. I also have an original OMC service manual on the way. Should be here on Friday.
Both motors fire right up, but the port side is giving me some issues. On muffs, it ran about 5 minutes, strong telltale stream, lots of water out the prop then I got an overheat alarm. With the amount of water its pumping and the new impeller I'm positive that isn't the problem.
I did notice once I ran the starboard engine, the exhaust cover stays cold to the touch. The port did not. Also, the starboard engine has a little water exiting the prop, but a ton of water coming out vents at the top rear of the cavitation plate. The overheating port had none. It seems to me this is where the water that cools the motor should exit, and I'm not getting flow through the engine.
After some reading I am now thinking thermostats, diverters, poppet valves should be addressed and while I'm in there check for any debris that would impeade any water flow or bleeding of air. It seems there are some common issues with these motors involving those parts.
I want to do both motors while I'm at it, so I believe that's 8 thermostats, 8 diverters, 8 poppets and springs?, 4 head gaskets. Finding these parts is a pain, but it seems most everything is available I just cant find it in the exploded views.
Is there any gaskets i will need besides head gaskets? I'm trying to get an order together ahead of time so i can knock it out and get on the water.
Any other words of wisdom that may be of use?
Thank you very much for the help!
