Hello to everyone, this forum looks really great. I have been reading and searching for the past few weeks and this forum is really awesome. Just recently my wife and I just bought our first boat, a 1984 Bayliner Capri 19ft. It needed alot of cleaning and care, and we are working on it whenever we can afford to.hhehehe <br />At any rate, I had it in this winter for storage and when when I got it out, I wanted the marina people to tune up the motor and clean it up. Well I think they turned up the idle and left it at that, cause the motor is dirty and has a few issues. I am ordering a clymer manual for this motor, as I don't know anything about outboard boat motors. I have worked on car engines before, but never outboards, and not point/magneto ignitions. <br />My problems are that the motor has low and mid rpm shakes, like it is missing most likely. I would like to add a tach to this motor, so if anyone knows where I can get one, that would be great. Also, when I got the boat out of service/storage, I lost about 10mph of top speed, so I am wondering if they did something to the linkage, (which looks like it controls throttle and timing advance). Also, I bought a new prop, as the one on the motor was really chewed up, and I went from a 15 to a 17, (learning what the pitches mean finally), and the engine does not whine out nearly as much as before and it is even slower with the 17, which is backwards I think. The boat still planes out, but keeps getting slower and slower. So now with the 17 pitch I am running about 25mph with two people and full tank, which is much slower than it should be.<br />Any suggestions?
