If anyone can offer some advice I would really appreciate it.
I have a 23' 1995 sea ray sundancer with a 5.0 merc/ alpha one second gen outdrive. stainless rapture prop
Problem: I have no thrust in higher rpm's and I am not able to get on plane
Possible reasons: 1) I keep the boat in the bay in wildwood without bottom paint, about 4 weeks of algae and barnacles grew on the bottom. Could this slow the boat down from 40 mph to 15? BTW I did pull it out and in the process of cleaning and bottom painting.
2) I also hit some fishing line that was tangled around the prop shaft. I removed prop and cut it out, the shaft seals looked fine without any oil leaking out.
3) Another possible reason is during mid tide near 15th st in north wildwood (needless to say how shallow and screwed up the channel is) I ran into some muc. I tilted the outdrive up a bit and pushed through only about 100ft.
After hitting the fishing line and also having the algae on bottom I was trying to get on plane by pushing the rpms up and the engine overheated. The buzzer came on and after a few boggs I was finally able to shut it off. I originally thought Something was preventing water to be sucked into the engine to cool it. After letting it cool down I removed the hose going to the thermostat and water was pumping through it so water pump is fine. I drove the boat back to my slip at about 1500 rpms, it seems to over heat only in high rpms.
The boat was running perfect about 3 weeks ago now all the sudden it won't move in high rpms?
Things it could be:
I took the prop to a specialist, he tested it said the hub inside prob is not spun. So it can't be the prop itself.
I heard theres a good possibility it could be the engine cupler. If engine is pushing 4000rpms and coupler is bad causing the cupler to slip then the engine will overheat because its not getting enough water to cool it, which had happened.
Or maybe it has something to do with the prop shaft?
Or could the outdrive need a rebuild?
What I will do first is clean and paint the bottom, put the prop back on and test it out.
If anyone has ever run into a problem like this can you please help me out with some advice.
Thank you
