    83 gt150 fuel pump hose routing

    I have a omc manual, the picture of the routing is too dark for me to see, but in some if the drawn pictures it shows the hose connecting the 2 pumps to be going straight, meaning it's really short. When I got my boat they had a long hose looped down from the top pump, coming down and going back...

    operating range question 83gt150

    I have a new to me 83 gt150, J150STLCTE on a 83 ranger 372v. I noticed the factory stamped operating range on my motor is 4500-5500 rpm. My question is, does this mean operating it below 4500 is considered 'lugging' the motor? I understand that of course running the boat for instance where its...

    83 johnson gt150 lake test #2 may have made serious mistake! UPDATE and TRIVIA

    J150STLCTE Well I got all my fuel lines replaced, cleaned carbs again after sucking bad gas (already rebuilt them), and rebuilt the fuel pumps. Motor was idling better than it ever has, and the 'dead' spot at low rpms was reduced as well. Still a little rough idle but smooth once on plane. Seems...

    83 gt150 charging volts too high?

    I put my motor on muffs today and fired it up, I'm trying to get the idle set right, and checked some ignition components on the way. Rectifier checked out ok before starting. I had 12.6 v at battery before starting, and 14.3 while at idle (1100-1200rpm) is this indication of faulty regulator? I...

    83 johnson gt150 compression test results, and need advice please

    Ok, the short re-cap so far: on my last lake test after rebuilding carbs I discovered that I had rotten fuel in at least one of my tanks. Up until the point I switched fuel tanks (ok fuel to rotten) the motor ran decent in neutral and once up on plane, but it still had a dead spot around 2000...
