I replaced a volvo penta engine witha Indmar 5.7L engine. Nightmare experience with installer. Enough said. No other marine dealers nearby. My problem is I am worried about timing. The installer said it was timed. I look at the TDC number under the flywheel and the notch is near 50-60. Am I looking at the wrong guage? The owners manual said it should be set at 10. It is carburated. Maybe the factory set it there. I am afraid to try it. What do I look for? The gauge numbers area is scuffed pretty good probably from Installation Help! |

The marks I read are on the lower front of ther motor just below and behind the belts. The marks go in a semi-circle from 0-60. The notch tool sticks out just between 50-60. I read the manual and it states the timing should be set at 8 or 10 DTC. What would be the symptoms if ran as set? I jsut can't find anyone to help. If I got a auto mechanic with a timing light, would it show everything is okay? Thanks Bondo |

Can I purchase a auto timing light or does it have to be a marine motor type. My motor is a 5.7L Indmar engine, 315HP, 4BL Holley either 600 or 650 CFM. Thanks. I really appreciate all the help. I am disabled and the motor installer really took me to the cleaners and was in over his head but didn't know it. He is a marine dealer but now I know why there are a lot of boats in his lot, he can't fix them! I changed from a 190hp 5.0 to a 5.7L 315hp. I will change the props once the motor is running right. My old motor block cracked. |
