Hello everyone! My name is Eddie and I am brand new to the forum and just purchased a 1989 Sea Ray 280 Sundancer with 4.3l Mercruiser V6s and bravo 1 out drives. I took my maiden voyage over the weekend to move the boat from one marina to another and ran into a few issues that the seller had made me aware of prior to purchase. 1. The starboard engine tachometer bounces around and just overall does not read anything close to the port engine tach. Both motors cranked and ran fine from what I could hear the entire 30-40 minute trip duration. 2. The starboard engine temperature gauge is also not reading correctly. It was not bouncing around or reading high, rather it was not registering any temperature at all which made me very anxious the entire trip to say the least. 3. The starboard engine throttle/shift cable seems to be stiff and is clunky when shifting into gear. I noticed that the engine RPMs also seemed to be a bit higher immediately after going into gear and it was hard to shift it back to neutral compared to the port engine. Could all 3 issues be somewhat related since they are all connected to the starboard engine? Should I start with the instrument panel first? Do I need the throttle cable to be replaced? Any and all help is most appreciated!
