Just wondering what boat you have and what props your running. I'm doing a re-power starting Monday with 150's. I have a 2509 Trophy with a hard top. 4400# bare boat. Add top, fuel, gear, full ice chests, 3 guys, camp, ect. and she may be getting up to 9000#++ The best all around props on my 130's are a pair of 13 1/2 x 13 4 blade SS. Lost cruise speed, but have great hole shot when loaded. Also use her at sea level, and at 3000 Ft. to make an all around prop hard to find.
My 2002 225 has only 310 hours and I was dismayed to see minor scoring on the driveshaft and the rubber around the bronze (?) bushing cold flowed into the 7/8" gap in the bushing housing. When I removed the bushing, the housing was caked with salt deposits, and I have been flushing faithfully with Salt Away since new! This thing is WATER LUBRICATED and the rubber surrounding the bushing has grooves in it so water flows between the rubber bushing and the housing. When this area builds up salt deposits, it distorts the rubber into the 7/8" gap and the bronze bushing starts wearing on the driveshaft. So far, this is the poorest design I have seen on my Honda. Some say to lubricate the bushing but I don't think any kind of grease will last very long in that area. Only thing I know to do is check that bearing, maybe yearly and if the the rubber is distorted into that 7/8 gap, pull it and replace it before it trashes your shaft or case. As for the Salt Away , ( I used it according to directions) I'm going to stop using it because of the oily, almost greasy salt deposits I found around the thermostats and other accessible passages in the motor.Happened with my 2003 200hp motor...
I only meant I'm not sure what the bushing is made of. Bronze colored, most likely a softer metal than the shaft.
