I have a 19' glass boat as well as a pontoon. I don't have any trouble at the ski jump landing.
I have not launched in Sayner proper in years...
When I was a kid a buddy at the woodlands resort took out the Jon boat and the motor somehow ended up in the lake. They hired a scuba diver to look for/retrieve it. The scuba diver said that he saw a few muskies where the motor went in that were so big it scared him. He found the motor and got out as fast as he could.
I've caught a few skis out of Plum up to 45 but I've seen some super tankers. Biggest musky I've ever encountered is swimming in Plum right now. No joke, 50lber. So yes, by all means musky fish Plum. You may strike out but you may also land the musky of a life time.
That whole area is the best. I spent many hours in the Star Lake Sayner Area. I had hoped to retire in that area, but it didn’t work out.
I remember several years ago one of the local guides caught a 50+ inch Musky out of Plum.
