    Ford 302 pinging

    That looks like it might have been a hot air choke instead of the well type choke common on Rochesters, there was a little piston inside that under vacuum pulled the choke plate open after the engine starts. https://www.carburetor-parts.com/rochester-2-jet-choke-system looky here. was it...

    Lower unit oil

    I’ve been using those for years on my Cobra they are much easier to deal with than the old slot style. The hex head Allen style won’t strip as long as you use the right size….keep in mind there are US size Allen fittings and Metric… Also ALWAYS replace those white fiber sealing gaskets! They get...

    3.8 OMC replacement motors?

    The decision of what to do all depends on how long you intend to keep the boat. If just a few years start searching for the older style GM V6 that used a 2 piece main seal that will work with your drive system. However if keeping it indefinitely rebuilding the transom to take a late model Merc...

    Ford 302 pinging

    Well go they this one & see if you can get it dialed in better. If not & you want to keep your 2 bbl intake you can use a Holley 2bbl 500 CFM marine carb; if not opposed to changing the intake to a 4 bbl, Holley or Edelbrock both can be bought new. The problem with all Rochesters is production...

    Ford 302 pinging

    Might want to read up on how the enrichment system works on the Rochester 2bbl. If you're getting pinging at WOT then if it is a carb related problem, adjusting the idle system won't have much if any effect on that problem. We had a Rochester 2GV on our '72 Chev Impala 350 and I always thought...

    Leaf Springs

    EPA regs? What a bunch of micromanaging hypocrites!! Why? Well they legislated all kinds of expensive to meet standards for cars trucks & now boats greatly increasing costs and complexity; yet they did nothing about one of the biggest environmental problems in NY State, affecting the drinking...

    Ford 302 pinging

    The caps for my Prestolite look better than that, after a year or 2 on my salt water mooring! The caps for mine do come with a gasket.

    Leaf Springs

    I've always greased my rollers and springs and never left a sheen. Now when that power steering actuator leaked and the bilge pump kicked on after it rained, that was a sheen. Fixed that one right away, was not a fun job but had to be done.

    Winterizing 4.3

    The 5th plug is only on '96 and up Vortec engines, the pre-Vortec did not have a drain there. Make sure to poke all the drains esp in the cast iron block and manifolds because they can get rust clogged and might not drain. Here's a pic of the 5th drain plug....

    Exhaust component inspection due to slight overheating

    If you have a 160 stat, anytime there is a load on the engine it should run slightly hotter than 160. The hottest I ever get on mine (raw water cooled in salt) is approx 175 and that's after coming off plane, it will cool down to about 165 after idling for a few min. Judging by the flappers you...

    I have that same style on mine very common style. I coat em with Evinrude triple guard grease when installing & spray with corrosion x 2 times a year keeps away the rust from salt water…

    Exhaust component inspection due to slight overheating

    Looking closer at pix flappers look overheated & warped but Elbows look good however I’d hook ‘em up to a water hose to see how they flow make sure they aren’t clogged. Lastly check for bubbles in the AF use clear hose to see if exhaust gas is getting into the coolant (leaky head gaskets). If...

    Exhaust component inspection due to slight overheating

    WAG=Wild a-s-s guess Flappers don’t cause overheats they get damaged due to running too hot (not enough water exiting to keep them cool). Do the clear hose test also if the elbows are more that 5 seasons used I’d change them. Is the boat kept in salt water? If so your water intakes might be...

    Old I/Os = Money Pits?

    This has the fume cartridges and N95 inserts but for grinding glass I'd use the big pink P-100 cartridges. I use it mostly when prepping the outdrive for anti fouling paint and painting it. I don't do the bottom, that's where I draw the line.

    Old I/Os = Money Pits?

    And that respirator should be a 3M full face shield with P-100 cartirdges. NOT a KN95 Covid mask, that ain't a respirator!

    Ford 302 pinging

    Look at your plugs first they can tell you a lot. Pinging can be tough to solve because it can be too much advance, lean fuel mix or even a slow to open auto choke that causes carbon build up which will cause chronic pinging. We had this very same problem on a ‘70 Ford with a 302. The choke...
