**Warning**
By no means am I any kind of mechanical or naval engineering expert... but I think know a little more than my nearest Yamaha Service Location...
Had some issues with my 2016 AR240 a four years back where my port impeller started scoring the impeller housing. Brought it to my local service location to have it replaced. Next Summer the boat worked great. What I didn't know at the time, is that the local shop used cheap gasket caulking to re-seal the thing up. Overtime I noted while getting to plane, my port engine would lose thrust around 14mph. It got so bad I was nearly fully dependent on my starboard engine to get to plane and get going. Thinking this was a cavitation issue I invested in some Lucky Cones which didn't help.
I finally had enough. After scouring through the threads, a few Youtube videos, and some IPAs for courage I took apart the port impeller drive. There was almost no seal left between the Transom Plate and the intake duct. The the cheap gasket sealant that was left behind was easy to pull off. Due to the corrosion, the air gap that was left was rather large and alarming. This is mainly due to the previous owner having the boat primarily in salt water and improper cleaning (I know, I know, it was a steal though).
After sealing the gap with 4200 (semi-permanent since ill have to replace the transom plate soon) and putting her back together, I was able to enjoy the rest of the summer with NO issues whatsoever. Hope this helps for those who are still scratching their heads. If someone actually knowledgeable thinks I did something incorrect please let me know....
