I must say that I have the same engine and when I realized I never got the proper RPMs, I checked the main shaft with a tachometer and found my tach was reading half the RPMs. I made a change on a selector on the Tach to get it closer to actual RPMs.
1) Loose Belt? The indicated RPM is generated by the alternator. The engine may be running fine while a loose belt will indicate low RPMs. If the engine runs and no RPMs indicated, the belt is broke. Check the belt to be sure it is tight. The sheaves are pretty close so no more than a belt width of flex is acceptable. Make sure the sheaves themselves are clean, no slippery surface.
2) Throttle lever blocked? With the engine stopped, check the throttle lever at the engine for full movement. It is remotely possible that something is jambing the lever. Look along the starboard side front of engine, above the water pump, for a lever with a control cable attached. You should be able to move the lever fairly easily. Next, start the engine and operate the throttle lever manually and increase speed from idle to full speed.

The saga continues and I am once again in need of advice from the group. When last we discussed my engine I was having starting problems. That seems to have been fixed by cleaning the grounds. Since that fix, the boat has been at anchor while I was away. Two weeks later, I returned to the boat for a beautiful day of sailing. When I started the engine on the way in, it started up reasonably quickly, but sounded rough at idle. Then I noticed that I could not accelerate. When I pushed the throttle all the way forward, there was only a small increase in revs or speed. It topped out well under 2000 rpm. Then I noticed black smoke coming from the exhaust. I backed off the throttle and slowly made my way to the anchorage and shut down. I am hard pressed to come up with an explanation for what could have happened while the boat was sitting at anchor to cause this problem. Suggestions? THanks- Dave
