My outboard engine repair expertise are nil.
Dad and I took the boat out on the river after having sat for 3-4 months. Tested everything before we left the house, idled fine, started right up, revved up just fine. He had the engine serviced after last time it was used.
In the water in the no wake zone, idled fine about 5 mph, dont have a tach so I dont know what rpm. When we tried to gun it out of the hole, it just died. Over and over. We had to limp back, it wouldn't go over 5-7 mph back and stalled out frequently.
I'm not 100% on this, but when we got back to the house, this evening I was looking the lower unit over. Found two problems.
1) wasp nest in what I THINK is the exhaust port above the prop.
2) a small hole below the fill plug for lower unit oil that was leaking a small stream of milky water contaminated oil out of it. (I found a crack in the lower unit by the prop that is probably the source of that.
My question's are
a) is this the exhaust port, if it is, would this wasp nest cause it not to accelerate under load, in the water, vs. on the trailer out of the water?
b) can a lower unit be repaid with a couple inch corroded crack, or repaired some other way?
c) where would these leaks be coming from to contaminate the oil, a prop shaft seal, or something else?
Edit: I removed the prop and the crack revealed the inner surface was an area where there is water inside anyway, so the crack is just a crack, I don't think its critical of operation. I also got a hook tool and pulled the wasp nest out. It was about 3" across and 1 1/2" thick.. on the upper area of what the picture shows. It was a lot of material.
