    Ford 302 spark plug read

    I found it helpful as I had a lean spot after hitting the throttle due to slop in accelerator pump circuit then I was too fat on the step up rods. I assume you have log not center riser exhaust manifolds? Not sure if these 02 adapters will fit your manifold and elbow configuration...

    on a gen two unless housing is scored there is no need. The stainless housing is much more robust than the earlier plastic ones. Merc has a kit with impeller baseplate and gaskets for about $55. Unless it was run dry forever thats all you need. Many places to buy but this is the oem kit merc...

    Since there is no water coming up from drive would back flush down that hose to see if u get water flow in reverse direction. If you dont there is a clogg somewhere. get the merc manual for your drive will see if i can do s9me screen shots of impeller work.

    4.3 mercrusier wires go to??

    Do you still have a TKS carb or do you have a mercarb with a choke? Possible someone swapped out a TKS for a electric choke carb. I think the execution of the tks carb was not one of Mercs shining moments... wouldn't surprise me if someone disconnected it.

    Revolution 14.6x19P vs 3-B something?

    The rev 4 s are crazy expensive now. different application but i run one on my 21 ft sea ray And really love it. Biggest advantage in my application was being able to use full trim with out blowing out. Gave me slightly higher top end and lower slip than an enertia ( standard enertia not eco)...

    Is my Mercruiser fuel injected or carb?

    The mercruiser 2 bbl intake is low rise and tame from a perf standpoint. The stock VP manifold Jimbo mentions is a performance design like the edlebrock and the no name cast iron one i use. i bought my engine as a partial from michigan motorz (“Silver Package”). Came with the cast iron intake...

    Power steering cooler is a shell and tube heat exchanger bout 8-10" long black tube hoses on either end back on the flywheel cover. Water supply comes up from outdrive to PS cooler, then up to thermostat housing. That's why if you check water flow there you can narrow issue down. if the water...
