    3.0 timing

    That number isn't quite right. There should be a serial number plate with something like 0C856451 or 7 numerals If that's missing, then the engine code is stamped on the block by the distributor.

    Battery low alarm

    Try wiring the Humminbird directly to the battery if it isn't already. If that solves the problem, you have a wiring issue.

    91 stingray 536 zpx tune up

    If it is the points type distributor how do the points etc. differ from the auto ones? I've been using that type for 40 years. No explosions so far!

    91 stingray 536 zpx tune up

    Can I install a newer outdrive?

    Looks like it goes to 14 lbs so that should work fine. Here's a link from the stickies. https://forums.iboats.com/threads/drive-pressure-vacuum-check.230980/

    Can You Make Up For Different Gear Ratio With a Different Pitch Prop?

    With your 140 it would be difficult to find a prop small enough to work with the 1.50 drive. You should put your engine and boat info in your signature.

    Hole shot, or up easy?

    I always advance the throttle to full in about 1 second and then once I know it's about to plane I start backing it off to my cruise setting. I don't like the bow up any longer than necessary.

    Causes for concern?
