Hello,
I am new to this forum and pretty new to the wonderful world of boating. I have switched from cars to the water and am so far loving it. I purchased my new boat, well new to me that it, a 1982 Sea Ray with a 120 Mercruiser Serial number 6028915. I do have a small concern, I think. I have read that wide open throttle on this machine is 4200-4600. Out on the water I can only get 3500 on a good day normally I will only see 3200. Wayyyy below. But it seems to be running its little heart out. I have replaced all of the fuel filters, it is a brand new tank of gas, checked to make sure linkage was allowing it to go to full throttle. Now the tricky part of this equation, I bought a timing light today and checked it, it is WAYYYYYYY off. The mark on the crank pulley, if it were a clock is WAYYYYY over at about 11 o'clock and the stationary timing marks are at about two o'clock. Now the boat runs pretty smooth, NOTHING like what it is telling me it SHOULD run like with the timing sooooo far off, OTHER than not getting to the WOT. It also bogs down alot when first starting out. Not sure if that helps or not. I checked to make sure that my wires were on correct by pacing the number one cylinder at TDC or close to and then verifying that my distributer thing that makes the spark, excuse me, I think it is called the rotor? is pointing towards the number one post, and it agrees with what the timing light told me. The mark on the crankshaft pulley is right at the eight degree mark and the rotor is almost already half way between the number one cylinder post and the next cylinder post. So is it possible that the boat is running SOOOOOO far advanced? I also TRIED to put the timing mark at the eight degree BTDC mark by rotating the whole distributer and it did NOT want to run AT ALL!!!! until I took it back to where it was before. What is happening to my baby!!!!!! Any help would be GREATLY appreciated!!!!!
