I'm starting on YEAR II of my 1992 Celebrity GM350/Yamaha Sterndrive run. Last year it worked out surprisingly well and trouble free despite the fear-mongering on the forums, lol, but I digress. My question has to do with the propeller availability. I know the Yamaha has a 15-spline output...
When I look up parts for my Yamaha stern drive, I can choose 5.7EST or 5.7YEMS. What does that mean? Does it have something to do with instrumentation? I ask because my depth finder & fuel gauge as the only ones that are accurate. The tach reads 2000 rpm low, temp is 85? cooler, and oil pressure...

Now I have another issue...when you start the engine, you can go forward or into reverse, but when transitioning from one to the...
OK, well my wife and I recently purchased my first boat. A 1992 Celebrity 190BR with a Yamaha 5.7L I/O engine. My question is as follows:
While pressure testing the cooling system, a core "freeze" plug behind the right engine mount popped out. What is the best way to support the engine while...
