Good day to all,<br /><br />I just purchased a 1983 50 Hp Merc (4 cylinder). It starts and runs well. When I go to full throttle, it bogs a little. I think that may be a timing issue. I have a new gas line and connectors and I replaced the plugs with L78V instead of the L76V that were in it. According to the new Teleflex tach I installed (I used the Merc wire harness from the remote box), it runs up to 4000 RPM. My book said it should be 5000-5500 RPM. I have noticed that when it takes off the prop spins out and acts like it has a second gear. I have moved the motor all the way in and a couple holes out and it still does it. My Ski boat acts this way when I take off and have it trimmed up. The prop is stainless and it has a ding or two in it. I was wondering how to check the hub or maybe move to another pitch prop. I can see a 14 on the prop hub but I can't not find the pitch. Where do I look for it?<br /><br />Thanks,<br /><br />Terry G.
